Title
ALSA: usb-audio: Cancel pending work at closing a MIDI substream
Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: Cancel pending work at closing a MIDI substream
At closing a USB MIDI output substream, there might be still a pending
work, which would eventually access the rawmidi runtime object that is
being released. For fixing the race, make sure to cancel the pending
work at closing.
Severity

Title
vc_screen: move load of struct vc_data pointer in vcs_read() to avoid UAF
Summary
In the Linux kernel, the following vulnerability has been resolved:
vc_screen: move load of struct vc_data pointer in vcs_read() to avoid UAF
After a call to console_unlock() in vcs_read() the vc_data struct can be
freed by vc_deallocate(). Because of that, the struct vc_data pointer
load must be done at the top of while loop in vcs_read() to avoid a UAF
when vcs_size() is called.
Syzkaller reported a UAF in vcs_size().
BUG: KASAN: use-after-free in vcs_size (drivers/tty/vt/vc_screen.c:215)

Title
scsi: iscsi_tcp: Fix UAF during login when accessing the shost ipaddress
Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: iscsi_tcp: Fix UAF during login when accessing the shost ipaddress
If during iscsi_sw_tcp_session_create() iscsi_tcp_r2tpool_alloc() fails,
userspace could be accessing the host's ipaddress attr. If we then free the
session via iscsi_session_teardown() while userspace is still accessing the
session we will hit a use after free bug.
Set the tcp_sw_host->session after we have completed session creation and
can no longer fail.

Title
netlink: prevent potential spectre v1 gadgets
Summary
In the Linux kernel, the following vulnerability has been resolved:
netlink: prevent potential spectre v1 gadgets
Most netlink attributes are parsed and validated from
__nla_validate_parse() or validate_nla()
u16 type = nla_type(nla);
if (type == 0 || type > maxtype) {
/* error or continue */
}
@type is then used as an array index and can be used
as a Spectre v1 gadget.
array_index_nospec() can be used to prevent leaking
content of kernel memory to malicious users.
This should take care of vast majority of netlink uses,
but an audit is needed to take care of others where
validation is not yet centralized in core netlink functions.
Severity
No CVSS data available.

Title
gve: Clear napi->skb before dev_kfree_skb_any()
Summary
In the Linux kernel, the following vulnerability has been resolved:
gve: Clear napi->skb before dev_kfree_skb_any()
gve_rx_free_skb incorrectly leaves napi->skb referencing an skb after it
is freed with dev_kfree_skb_any(). This can result in a subsequent call
to napi_get_frags returning a dangling pointer.
Fix this by clearing napi->skb before the skb is freed.

The error path can be provoked repeatedly at line rate until it lands.\nPR:N - There is no syscall, ioctl, socket, capability check or authentication anywhere on the path; the receive poll runs unconditionally on incoming frames. An entirely unauthenticated off-host attacker can reach it.\nUI:N - No victim action is required \u2014 the driver processes received packets automatically in softirq context. Simply having the interface up is sufficient.\nS:U - The corruption is confined to the kernel\u0027s own memory within the same security authority; there is no crossing of a VM, IOMMU or sandbox boundary. Standard kernel-level compromise is Unchanged.\nC:H - The stale napi-\u003eskb is a freed sk_buff on the heavily-sprayable skbuff_head_cache; the driver and the subsequent napi_gro_frags/GRO path read skb-\u003ehead, skb-\u003edata, skb_headlen and skb_shinfo from reallocated memory, so attacker-groomed or unrelated kernel data is parsed and can be leaked out via the receive path.\nI:H - The dangling pointer is written through \u2014 skb_add_rx_frag updates len/data_len/truesize and skb_shinfo, and gve_rx_complete_skb writes hash, ip_summed, gso_type and gso_size into freed memory \u2014 giving a write-after-free into a general-purpose slab plus a subsequent double free, which is the classic basis for control-flow hijack and privilege escalation.\nA:H - Use of the freed sk_buff reliably produces slab corruption, KASAN splats, list corruption and kernel panics, and the double free of the skb compounds this. A remote attacker can crash the host repeatedly."

Bluetooth radio proximity is required, matching the Adjacent classification.\nAC:L - The attacker controls both sides of the race: `SO_SNDTIMEO` sets `sk-\u003esk_sndtimeo`, which `iso_connect_cis()`/`iso_connect_bis()` pass verbatim to `iso_sock_set_timer()`, so the timeout work can be scheduled to fire at an arbitrarily chosen moment and raced against `close()`, and `iso_sock_clear_timer()` uses non-sync `cancel_delayed_work()` so an in-flight work item is never waited for. The sequence is freely repeatable until it wins.\nPR:L - There is no `capable()` or `CAP_NET_*` check anywhere in `bt_sock_create()`, `iso_sock_create()`, `iso_sock_bind()`, `iso_sock_listen()` or `iso_sock_connect()`, so any unprivileged local user can create BTPROTO_ISO sockets and drive the connect/close sequence that frees the socket. Only basic local account access is needed, not root.\nUI:N - The whole sequence \u2014 socket creation, `SO_SNDTIMEO`, connect/listen, close \u2014 is performed by the attacker\u0027s own process against the system Bluetooth adapter. No victim action is required.\nS:U - The use-after-free corrupts kernel heap memory within the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - `iso_proto` is registered with `proto_register(\u0026iso_proto, 0)`, so `struct iso_pinfo` is allocated from the generic kmalloc caches; the attacker can respray the freed object and read its contents back through subsequent socket operations, giving a path to arbitrary kernel memory disclosure.\nI:H - The stale pointer is written through \u2014 `sock_hold()` performs an atomic increment on freed memory and `sk-\u003esk_err = ETIMEDOUT` writes into it \u2014 and `sk-\u003esk_state_change(sk)` performs an indirect call through a function pointer read from the freed object, providing a control-flow hijack primitive.\nA:H - Even without successful exploitation the UAF produces a KASAN splat, oops, or panic inside `iso_sock_timeout()` running on the system workqueue, and it can be triggered repeatedly by an unprivileged process."
