kernel: ip6_tunnel: clear skb2->cb[] in ip4ip6_err()
A flaw was found in the Linux kernel's IPv6 tunnel implementation. A remote attacker could exploit this flaw by sending malicious ICMPv6 error messages to cause a stack-based buffer overflow in the kernel's IPv4-over-IPv6 tunnel error handling code. This could result in a kernel crash denial of...

CVE-2026-46303
A flaw was found in the Linux kernel's isofs filesystem. This vulnerability allows a local attacker, by mounting a specially crafted ISO image, to read data beyond the boundaries of the intended ISO 9660 volume. This out-of-bounds read could lead to information disclosure, potentially exposing...
CVE-2026-52911
A flaw was found in the ksmbd component of the Linux kernel. This vulnerability allows an attacker to gain unauthorized access to session information or resources by exploiting an improper scope in the session binding mechanism. This could potentially compromise the integrity or confidentiality o...
CVE-2026-52909
A flaw was found in the Linux kernel, specifically within the IPv6 Virtual Tunnel Interface ip6vti component. This vulnerability occurs because a critical flag, netnsimmutable, is not properly set on a specific network device ip6vti0 when it is initialized. This oversight could allow the device t...
CVE-2026-52908
A flaw was found in the Linux kernel. This vulnerability occurs during the re-registration of a Remote Direct Memory Access RDMA memory region. If the memory's access permissions are changed from read-only to read-write, the system may fail to properly update and secure the underlying user memory...
CVE-2026-52910
A flaw was found in the Linux kernel's Berkeley Packet Filter BPF reuseport mechanism. When a cBPF program is detached from a reuseport group, it is freed immediately without waiting for Read-Copy-Update RCU readers to complete. This can lead to a use-after-free condition, resulting in memory...
kernel: Linux kernel: Use-After-Free in net/gro due to improper handling of zerocopy skbs
A flaw was found in the Linux kernel's Generic Receive Offload GRO networking subsystem. This vulnerability occurs when skbgroreceive attempts to merge zerocopy socket buffers skbs without properly managing page reference counts, specifically when the SKBFLMANAGEDFRAGREFS flag is set. An attacker...
kernel: Linux kernel: smb: client: reject userspace cifs.spnego descriptions
A privilege escalation vulnerability was found in the Linux kernel's CIFS client implementation. This could allow a local attacker to impersonate other users, bypass authentication in SMB mount operations, and potentially gain unauthorized access to network file shares or escalate privileges...
kernel: xfs: fix freemap adjustments when adding xattrs to leaf blocks
A flaw was found in the Linux kernel's XFS filesystem. When adding extended attributes xattrs, which are metadata associated with files, to leaf blocks, incorrect adjustments to the freemap can occur. This inconsistency allows the entries array and free space to overlap, leading to an assertion...
kernel: mm/page_alloc: clear page->private in free_pages_prepare()
A flaw was found in the Linux kernel's memory management subsystem. When pages are freed, the page-private field is not properly cleared. If these pages are later reallocated as high-order pages and split, the tail pages can retain stale page-private values. This can lead to a use-after-free...
kernel: Linux kernel: Denial of Service in libceph OSD client due to unreset sparse-read state
A flaw was found in the Linux kernel's libceph OSD client. When a connection fault occurs during a sparse read, the sparse-read state is not properly reset. This allows a misbehaving or compromised Ceph OSD server, or a network adversary, to disrupt traffic. As a result, the client can misinterpr...
kernel: wifi: mac80211: use safe list iteration in radar detect work
A flaw was found in the Linux kernel's mac80211 wireless subsystem. This vulnerability arises from unsafe list iteration during radar detection work, where a channel context can be freed while still being processed. This can lead to a use-after-free memory error. A successful exploit could result...
kernel: net/sched: act_pedit: extend the writable skb range per key
A flaw was found in the Linux kernel's traffic control packet editing pedit subsystem. In tcfpeditact, the copy-on-write COW range for skbensurewritable is computed once before iterating over edit keys, but the calculation does not account for runtime header offsets added by typed keys. This can...
kernel: libceph: replace overzealous BUG_ON in osdmap_apply_incremental()
In the Linux kernel, the following vulnerability has been resolved: libceph: replace overzealous BUGON in osdmapapplyincremental If the osdmap is maliciously corrupted such that the incremental osdmap epoch is different from what is expected, there is no need to BUG. Instead, just declare the...
kernel: libceph: prevent potential out-of-bounds reads in handle_auth_done()
In the Linux kernel, the following vulnerability has been resolved: libceph: prevent potential out-of-bounds reads in handleauthdone Perform an explicit bounds check on payloadlen to avoid a possible out-of-bounds access in the callout. idryomov: changelog...

kernel: wifi: mac80211: remove station if connection prep fails
A flaw was found in the Linux kernel's mac80211 Wi-Fi subsystem. When Multi-Link Operation MLO connection preparation fails, the system may not correctly remove the associated station. This can lead to a use-after-free or double-free vulnerability in the debugfs component, potentially causing...
