CVE-2025-38154

A flaw was found in the Linux kernel's BPF (Berkeley Packet Filter) sockmap subsystem. A race condition exists where the `sk_socket` is not properly locked or referenced during the `skb_send_sock()` function call, allowing for a use-after-free vulnerability. This can be exploited by a local attacker, leading to a system crash (Denial of Service) and potentially enabling information disclosure or privilege escalation.

CVE-2026-45898

A flaw was found in the Linux kernel's Remote Direct Memory Access (RDMA) Internet Wide Area RDMA Protocol (iWARP) subsystem. Incorrect work submission logic in the `iwcm` component can lead to multiple queueing of work items. This allows a work item to be processed and freed while still present in the workqueue, causing list corruption. A successful exploitation of this vulnerability can result in a kernel bug and system crash, leading to a Denial of Service (DoS).

CVE-2026-46227

A flaw was found in the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation. A race condition exists in the `SCTP_SENDALL` path where a cached list entry is not properly revalidated after the socket lock is temporarily released. This allows a local attacker or a remote attacker (via a network abort) to trigger a use-after-free or type confusion vulnerability. Successful exploitation can lead to a controlled indirect call, potentially resulting in arbitrary code execution.

CVE-2026-46323

A flaw was found in the Linux kernel's Generic Receive Offload (GRO) networking subsystem. This vulnerability occurs when `skb_gro_receive()` attempts to merge zerocopy socket buffers (skbs) without properly managing page reference counts, specifically when the `SKBFL_MANAGED_FRAG_REFS` flag is set. An attacker could potentially exploit this to trigger a Use-After-Free (UAF) condition, which is a memory corruption vulnerability that can lead to system instability or potentially arbitrary code execution.

7.8 (High)

CVE-2026-46331

A flaw was found in the Linux kernel's traffic control packet editing (pedit) subsystem. In tcf_pedit_act(), the copy-on-write (COW) range for skb_ensure_writable() is computed once before iterating over edit keys, but the calculation does not account for runtime header offsets added by typed keys. This can leave part of the target write region without a proper copy-on-write, leading to an out-of-bounds write that corrupts page cache memory. A local attacker with the ability to configure traffic control rules could exploit this to escalate privileges or crash the system.

6.7 (Medium)

Title

bpf, sockmap: Avoid using sk_socket after free when sending

Summary

In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Avoid using sk_socket after free when sending The sk->sk_socket is not locked or referenced in backlog thread, and during the call to skb_send_sock(), there is a race condition with the release of sk_socket. All types of sockets(tcp/udp/unix/vsock) will be affected. Race conditions: ''' CPU0 CPU1 backlog::skb_send_sock sendmsg_unlocked sock_sendmsg sock_sendmsg_nosec close(fd): ... ops->release() -> sock_map_close() sk_socket->ops = NULL free(socket) sock->ops->sendmsg ^ panic here ''' The ref of psock become 0 after sock_map_close() executed. ''' void sock_map_close() { ... if (likely(psock)) { ... // !! here we remove psock and the ref of psock become 0 sock_map_remove_links(sk, psock) psock = sk_psock_get(sk); if (unlikely(!psock)) goto no_psock; <=== Control jumps here via goto ... cancel_delayed_work_sync(&psock->work); <=== not executed sk_psock_put(sk, psock); ... } ''' Based on the fact that we already wait for the workqueue to finish in sock_map_close() if psock is held, we simply increase the psock reference count to avoid race conditions. With this patch, if the backlog thread is running, sock_map_close() will wait for the backlog thread to complete and cancel all pending work. If no backlog running, any pending work that hasn't started by then will fail when invoked by sk_psock_get(), as the psock reference count have been zeroed, and sk_psock_drop() will cancel all jobs via cancel_delayed_work_sync(). In summary, we require synchronization to coordinate the backlog thread and close() thread. The panic I catched: ''' Workqueue: events sk_psock_backlog RIP: 0010:sock_sendmsg+0x21d/0x440 RAX: 0000000000000000 RBX: ffffc9000521fad8 RCX: 0000000000000001 ...

No condition outside its influence is required.\nPR:L - An unprivileged local process suffices in the real deployments of this feature (Cilium/Istio sockops redirect, BPF-token-delegated containers), where a privileged agent enrols workload sockets into the sockmap and the attacker only needs to send/redirect data and close its own fd.\nUI:N - No victim action is needed; the attacker drives both the traffic and the close from its own process.\nS:U - The use-after-free and any resulting corruption remain within the kernel\u0027s own security authority, with no VM, IOMMU, or sandbox boundary crossed.\nC:H - Use-after-free on `struct socket` \u2014 the freed object can be resprayed from `sock_inode_cachep`, causing redirected payload to be transmitted through a stale/attacker-influenced socket and permitting kernel memory disclosure.\nI:H - `security_socket_sendmsg()` and `READ_ONCE(sock-\u003eops)-\u003esendmsg` dereference and indirect-call through a pointer loaded from freed memory, giving a control-flow hijack primitive once the freed `struct socket` is reclaimed with attacker-groomed contents.\nA:H - The maintainer reproduced a general-protection fault in `sock_sendmsg()` from the `sk_psock_backlog` workqueue; the NULLed `sock-\u003eops` alone guarantees a fatal kernel oops in worker context."

CVE-2026-23136 (GCVE-0-2026-23136)

Vulnerability from cvelistv5 – Published: 2026-02-14 15:22 – Updated: 2026-08-05 12:20

Title

libceph: reset sparse-read state in osd_fault()

Summary

In the Linux kernel, the following vulnerability has been resolved: libceph: reset sparse-read state in osd_fault() When a fault occurs, the connection is abandoned, reestablished, and any pending operations are retried. The OSD client tracks the progress of a sparse-read reply using a separate state machine, largely independent of the messenger's state. If a connection is lost mid-payload or the sparse-read state machine returns an error, the sparse-read state is not reset. The OSD client will then interpret the beginning of a new reply as the continuation of the old one. If this makes the sparse-read machinery enter a failure state, it may never recover, producing loops like: libceph: [0] got 0 extents libceph: data len 142248331 != extent len 0 libceph: osd0 (1)...:6801 socket error on read libceph: data len 142248331 != extent len 0 libceph: osd0 (1)...:6801 socket error on read Therefore, reset the sparse-read state in osd_fault(), ensuring retries start from a clean state.

CVE-2026-31474 (GCVE-0-2026-31474)

Vulnerability from cvelistv5 – Published: 2026-04-22 13:54 – Updated: 2026-08-05 12:22

Title

can: isotp: fix tx.buf use-after-free in isotp_sendmsg()

Summary

In the Linux kernel, the following vulnerability has been resolved: can: isotp: fix tx.buf use-after-free in isotp_sendmsg() isotp_sendmsg() uses only cmpxchg() on so->tx.state to serialize access to so->tx.buf. isotp_release() waits for ISOTP_IDLE via wait_event_interruptible() and then calls kfree(so->tx.buf). If a signal interrupts the wait_event_interruptible() inside close() while tx.state is ISOTP_SENDING, the loop exits early and release proceeds to force ISOTP_SHUTDOWN and continues to kfree(so->tx.buf) while sendmsg may still be reading so->tx.buf for the final CAN frame in isotp_fill_dataframe(). The so->tx.buf can be allocated once when the standard tx.buf length needs to be extended. Move the kfree() of this potentially extended tx.buf to sk_destruct time when either isotp_sendmsg() and isotp_release() are done.

Severity

7.8 (High)

CVE-2026-43116 (GCVE-0-2026-43116)

Vulnerability from cvelistv5 – Published: 2026-05-06 07:40 – Updated: 2026-09-08 08:48

Title

netfilter: ctnetlink: ensure safe access to master conntrack

Summary

In the Linux kernel, the following vulnerability has been resolved: netfilter: ctnetlink: ensure safe access to master conntrack Holding reference on the expectation is not sufficient, the master conntrack object can just go away, making exp->master invalid. To access exp->master safely: - Grab the nf_conntrack_expect_lock, this gets serialized with clean_from_lists() which also holds this lock when the master conntrack goes away. - Hold reference on master conntrack via nf_conntrack_find_get(). Not so easy since the master tuple to look up for the master conntrack is not available in the existing problematic paths. This patch goes for extending the nf_conntrack_expect_lock section to address this issue for simplicity, in the cases that are described below this is just slightly extending the lock section. The add expectation command already holds a reference to the master conntrack from ctnetlink_create_expect(). However, the delete expectation command needs to grab the spinlock before looking up for the expectation. Expand the existing spinlock section to address this to cover the expectation lookup. Note that, the nf_ct_expect_iterate_net() calls already grabs the spinlock while iterating over the expectation table, which is correct. The get expectation command needs to grab the spinlock to ensure master conntrack does not go away. This also expands the existing spinlock section to cover the expectation lookup too. I needed to move the netlink skb allocation out of the spinlock to keep it GFP_KERNEL. For the expectation events, the IPEXP_DESTROY event is already delivered under the spinlock, just move the delivery of IPEXP_NEW under the spinlock too because the master conntrack event cache is reached through exp->master. While at it, add lockdep notations to help identify what codepaths need to grab the spinlock.

Severity

7.8 (High)

Expand the existing spinlock\nsection to address this to cover the expectation lookup. Note that,\nthe nf_ct_expect_iterate_net() calls already grabs the spinlock while\niterating over the expectation table, which is correct.\n\nThe get expectation command needs to grab the spinlock to ensure master\nconntrack does not go away. This also expands the existing spinlock\nsection to cover the expectation lookup too. I needed to move the\nnetlink skb allocation out of the spinlock to keep it GFP_KERNEL.\n\nFor the expectation events, the IPEXP_DESTROY event is already delivered\nunder the spinlock, just move the delivery of IPEXP_NEW under the\nspinlock too because the master conntrack event cache is reached through\nexp-\u003emaster.\n\nWhile at it, add lockdep notations to help identify what codepaths need\nto grab the spinlock."

Title

ipv6: rpl: reserve mac_len headroom when recompressed SRH grows

Summary

In the Linux kernel, the following vulnerability has been resolved: ipv6: rpl: reserve mac_len headroom when recompressed SRH grows ipv6_rpl_srh_rcv() decompresses an RFC 6554 Source Routing Header, swaps the next segment into ipv6_hdr->daddr, recompresses, then pulls the old header and pushes the new one plus the IPv6 header back. The recompressed header can be larger than the received one when the swap reduces the common-prefix length the segments share with daddr (CmprI=0, CmprE>0, seg[0][0] != daddr[0] gives the maximum +8 bytes). pskb_expand_head() was gated on segments_left == 0, so on earlier segments the push consumed unchecked headroom. Once skb_push() leaves fewer than skb->mac_len bytes in front of data, skb_mac_header_rebuild()'s call to: skb_set_mac_header(skb, -skb->mac_len); will store (data - head) - mac_len into the u16 mac_header field, which wraps to ~65530, and the following memmove() writes mac_len bytes ~64KiB past skb->head. A single AF_INET6/SOCK_RAW/IPV6_HDRINCL packet over lo with a two segment type-3 SRH (CmprI=0, CmprE=15) reaches headroom 8 after one pass; KASAN reports a 14-byte OOB write in ipv6_rthdr_rcv. Fix this by expanding the head whenever the remaining room is less than the push size plus mac_len, and request that much extra so the rebuilt MAC header fits afterwards.

Title

RDMA/iwcm: Fix workqueue list corruption by removing work_list

Summary

In the Linux kernel, the following vulnerability has been resolved: RDMA/iwcm: Fix workqueue list corruption by removing work_list The commit e1168f0 ("RDMA/iwcm: Simplify cm_event_handler()") changed the work submission logic to unconditionally call queue_work() with the expectation that queue_work() would have no effect if work was already pending. The problem is that a free list of struct iwcm_work is used (for which struct work_struct is embedded), so each call to queue_work() is basically unique and therefore does indeed queue the work. This causes a problem in the work handler which walks the work_list until it's empty to process entries. This means that a single run of the work handler could process item N+1 and release it back to the free list while the actual workqueue entry is still queued. It could then get reused (INIT_WORK...) and lead to list corruption in the workqueue logic. Fix this by just removing the work_list. The workqueue already does this for us. This fixes the following error that was observed when stress testing with ucmatose on an Intel E830 in iWARP mode: [ 151.465780] list_del corruption. next->prev should be ffff9f0915c69c08, but was ffff9f0a1116be08.

The problem is\nthat a free list of struct iwcm_work is used (for which\nstruct work_struct is embedded), so each call to queue_work()\nis basically unique and therefore does indeed queue the work.\n\nThis causes a problem in the work handler which walks the work_list\nuntil it\u0027s empty to process entries. This means that a single\nrun of the work handler could process item N+1 and release it\nback to the free list while the actual workqueue entry is still\nqueued. It could then get reused (INIT_WORK...) and lead to\nlist corruption in the workqueue logic.\n\nFix this by just removing the work_list. The workqueue already\ndoes this for us.\n\nThis fixes the following error that was observed when stress\ntesting with ucmatose on an Intel E830 in iWARP mode:\n\n[  151.465780] list_del corruption. next-\u003eprev should be ffff9f0915c69c08, but was ffff9f0a1116be08.
