Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftables – Release flowtable after the rcu grace period with an error. The function synchronizercu is called after unregistering the hooks from the error path. This is because a hook that already references this...

kernel: smc: Use __sk_dst_get() and dst_dev_rcu() in smc_clc_prfx_match()

A flaw was found in the Linux kernel’s SMC Shared Memory Communication module: in smcclcprfxmatch, the function is called from smclistenwork without proper RCU or RTNL protection. The code previously used skdstgetsk-dev, which can lead to a use-after-free UAF condition if the sk’s destination is...

kernel: smc: Fix use-after-free in __pnet_find_base_ndev()

In the Linux kernel, the following vulnerability has been resolved: smc: Fix use-after-free in pnetfindbasendev. syzbot reported use-after-free of netdevice in pnetfindbasendev, which was called during connect. 0 smcpnetfindismresource fetches skdstgetsk-dev and passes down to pnetfindbasendev,...

kernel: net: use dst_dev_rcu() in sk_setup_caps()

In the Linux kernel, the following vulnerability has been resolved: net: use dstdevrcu in sksetupcaps Use RCU to protect accesses to dst-dev from sksetupcaps and skdstgsomaxsize. Also use dstdevrcu in ip6dstmtumaybeforward, and ipdstmtumaybeforward. ip4dsthoplimit can use dstdevnetrcu...

CVE-2026-52910

The CVE-2026-52910 issue is in the Linux kernel where a cBPF reuseport program may be freed immediately when detached from a reuseport group, without waiting for an RCU grace period. This can lead to a use-after-free and potential memory corruption when a concurrent UDP send crosses the fast path...
