CVE-2026-53212

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfttunnel: fix use-after-free on object destroy nfttunnelobjdestroy calls metadatadstfree which directly kfrees the metadatadst, ignoring the dstentry refcount. Packets that took a reference via dsthold in...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: ipvs: Do not keep the destdst entry if the device is going down. There is a race between the netdevnotifier function ipvsdstevent and the code that caches the dst entry for devices that are going down. Since the FIB can be notifi...

EUVD-2026-32799

In the Linux kernel, the following vulnerability has been resolved: ipv6: xfrm6: release dst on error in xfrm6rcvencap xfrm6rcvencap performs an IPv6 route lookup when the skb does not already have a dst attached. ip6routeinputlookup returns a referenced dst entry even when the lookup resolves to...

PT-2026-44295

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A memory leak occurs in the Linux kernel within the xfrm6 rcv encap function. When performing an IPv6 route lookup, the ip6 route input lookup function returns a referenced destination d...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfreject: Do not leak the destination refcount for loopback packets. Recent patches that added a warning when replacing the skb dst entry fixed an old bug. WARNINGS: - include/linux/skbuff.h:1165: skbdstcheckunset →...

PT-2025-36262

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A flaw exists in the Linux kernel's netfilter module, specifically within the nf reject functionality. The issue involves a potential information leak of the destination reference count...

kernel: tipc: force a dst refcount before doing decryption

A vulnerability was found in the Linux kernel's TIPC module, where a reference count on the destination entry was not enforced before decryption. This issue arises due to potential asynchronous returns from crypto requests, which could lead to crash...

The vulnerability of the UDPv6 network protocol implementation in Linux operating systems allows attackers to cause service failures.

The vulnerability of the UDPv6 network protocol implementation in Linux operating systems is related to concurrent access to the dstentry structure during a race condition, due to the lack of synchronization in the sksetupcaps function within the net/core/sock.c module. Exploiting this...
