Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: xfrm: esp: avoid in-place decrypt on shared skb frags The MSGSPLICEPAGES function can attach pages from a pipe directly to an skb. TCP marks such skbs with SKBFLSHAREDFRAG after skbsplicefromiter, so later processes that may modi...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net: skbuff: Preserve the shared-frag marker during coalescing The skbtrycoalesce function can attach paged fragments from @from to @to. If @from has the SKBFLSHAREDFRAG flag set, the resulting @to skb can contain the same...

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: Linux kernel: Use-after-free in bonding driver leads to denial of service

A flaw was found in the Linux kernel's bonding driver. A local attacker with low privileges could exploit a use-after-free vulnerability in the bondxmitbroadcast function. This occurs due to a race condition during concurrent slave enslave/release operations, which can lead to the original socket...

CVE-2026-46322

In the Linux kernel, the following vulnerability has been resolved: tun: free page on buildskb failure in tunxdpone When buildskb fails in tunxdpone, the function sets ret to -ENOMEM and jumps to the out label, which returns without freeing the page that vhostnetbuildxdp allocated for the frame. ...
