CVE-2026-43112 (GCVE-0-2026-43112)

Vulnerability from cvelistv5 – Published: 2026-05-06 07:40 – Updated: 2026-07-07 12:05

Title

fs/smb/client: fix out-of-bounds read in cifs_sanitize_prepath

Summary

In the Linux kernel, the following vulnerability has been resolved: fs/smb/client: fix out-of-bounds read in cifs_sanitize_prepath When cifs_sanitize_prepath is called with an empty string or a string containing only delimiters (e.g., "/"), the current logic attempts to check *(cursor2 - 1) before cursor2 has advanced. This results in an out-of-bounds read. This patch adds an early exit check after stripping prepended delimiters. If no path content remains, the function returns NULL. The bug was identified via manual audit and verified using a standalone test case compiled with AddressSanitizer, which triggered a SEGV on affected inputs.

CVE-2026-45998 (GCVE-0-2026-45998)

Vulnerability from cvelistv5 – Published: 2026-05-27 12:55 – Updated: 2026-07-03 12:05

Title

rxrpc: Fix potential UAF after skb_unshare() failure

Summary

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix potential UAF after skb_unshare() failure If skb_unshare() fails to unshare a packet due to allocation failure in rxrpc_input_packet(), the skb pointer in the parent (rxrpc_io_thread()) will be NULL'd out. This will likely cause the call to trace_rxrpc_rx_done() to oops. Fix this by moving the unsharing down to where rxrpc_input_call_event() calls rxrpc_input_call_packet(). There are a number of places prior to that where we ignore DATA packets for a variety of reasons (such as the call already being complete) for which an unshare is then avoided. And with that, rxrpc_input_packet() doesn't need to take a pointer to the pointer to the packet, so change that to just a pointer.

Severity

7 (High)

CVE-2026-46209 (GCVE-0-2026-46209)

Vulnerability from cvelistv5 – Published: 2026-05-28 09:40 – Updated: 2026-06-14 18:02

Title

drm/gem: Fix inconsistent plane dimension calculation in drm_gem_fb_init_with_funcs()

Summary

In the Linux kernel, the following vulnerability has been resolved: drm/gem: Fix inconsistent plane dimension calculation in drm_gem_fb_init_with_funcs() drm_gem_fb_init_with_funcs() computes sub-sampled plane dimensions using plain integer division: unsigned int width = mode_cmd->width / (i ? info->hsub : 1); unsigned int height = mode_cmd->height / (i ? info->vsub : 1); However, the ioctl-level framebuffer_check() in drm_framebuffer.c uses drm_format_info_plane_width/height() which round up dimensions via DIV_ROUND_UP(). This inconsistency corrupts the subsequent GEM object size check for certain pixel format and dimension combinations. For example, with NV12 (vsub=2) and a 1-pixel-tall framebuffer the GEM size validation path sees height=0 instead of height=1. The expression (height - 1) then wraps to UINT_MAX as an unsigned int, causing min_size to overflow and wrap back to a small value. A tiny GEM object therefore passes the size guard, yet when the GPU accesses the chroma plane it will read or write memory beyond the object's bounds. Fix by replacing the open-coded divisions with drm_format_info_plane_width() and drm_format_info_plane_height(), which use DIV_ROUND_UP() and match the calculation already used in framebuffer_check().

CVE-2026-46244 (GCVE-0-2026-46244)

Vulnerability from cvelistv5 – Published: 2026-06-03 15:48 – Updated: 2026-07-07 12:04

Title

netfilter: nft_inner: Fix IPv6 inner_thoff desync

Summary

In the Linux kernel, the following vulnerability has been resolved: netfilter: nft_inner: Fix IPv6 inner_thoff desync In nft_inner_parse_l2l3(), when processing inner IPv6 packets, ipv6_find_hdr() correctly computes the transport header offset traversing all extension headers, but the result is immediately overwritten with nhoff + sizeof(_ip6h) (40 bytes), which only accounts for the IPv6 base header. This creates a desync between inner_thoff (wrong — points to extension header start) and l4proto (correct — e.g., IPPROTO_TCP), enabling transport header forgery and potential firewall bypass. This issue affects stable versions from Linux 6.2. For comparison, the normal (non-inner) IPv6 path correctly preserves ipv6_find_hdr()'s result. Removing the incorrect overwrite ensures that ipv6_find_hdr()'s calculated transport header offset is preserved, thereby fixing the desynchronization.

This creates a desync between\ninner_thoff (wrong \u2014 points to extension header start) and l4proto\n(correct \u2014 e.g., IPPROTO_TCP), enabling transport header forgery\nand potential firewall bypass. This issue affects stable versions\nfrom Linux 6.2.\n\nFor comparison, the normal (non-inner) IPv6 path correctly\npreserves ipv6_find_hdr()\u0027s result.

CVE-2026-46316 (GCVE-0-2026-46316)

Vulnerability from cvelistv5 – Published: 2026-06-09 11:52 – Updated: 2026-07-07 12:04

Title

KVM: arm64: vgic-its: Drop the translation cache reference only for the erased entry

Summary

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: vgic-its: Drop the translation cache reference only for the erased entry vgic_its_invalidate_cache() walks the per-ITS translation cache with xa_for_each() and drops the cache's reference on each entry with vgic_put_irq(). It puts the iterated pointer, though, rather than the value returned by xa_erase(). The function is called from contexts that do not exclude one another: the ITS command handlers hold its_lock, the GITS_CTLR write path holds cmd_lock, and the path that clears EnableLPIs in a redistributor's GICR_CTLR holds neither. Two or more of them can drain the same cache concurrently, and if each one observes the same entry, erases it and then puts it, the single reference the cache holds on that entry is dropped more than once. The entry can then be freed while an ITE still maps it. xa_erase() is atomic and returns the previous entry, so put only the entry that this context actually removed. The cache reference is then dropped exactly once per entry even when the invalidations run concurrently, and the behavior is unchanged when only one context runs.

It puts the iterated pointer, though, rather than the\nvalue returned by xa_erase().\n\nThe function is called from contexts that do not exclude one another: the\nITS command handlers hold its_lock, the GITS_CTLR write path holds\ncmd_lock, and the path that clears EnableLPIs in a redistributor\u0027s\nGICR_CTLR holds neither. Two or more of them can drain the same cache\nconcurrently, and if each one observes the same entry, erases it and then\nputs it, the single reference the cache holds on that entry is dropped\nmore than once. The entry can then be freed while an ITE still maps it.\n\nxa_erase() is atomic and returns the previous entry, so put only the entry\nthat this context actually removed. The cache reference is then dropped\nexactly once per entry even when the invalidations run concurrently, and\nthe behavior is unchanged when only one context runs."
