CVE-2026-98036

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. A local user with permission to run BPF programs can trigger a use-after-free condition, potentially leading to a system crash, denial of service DoS, or privilege escalation. This flaw occurs during the recycling of...

CVE-2026-93211

In the Linux kernel, the following vulnerability has been resolved: nfsd: initialize DRC hash table before registering shrinker shrinkerregister precedes the INITLISTHEAD loop and the drchashsize store. On weakly-ordered architectures arm64, ppc, a shrinker scan can observe drchashsize before the...

CVE-2026-93211

The Linux kernel contains a vulnerability in the nfsd component where the DRC hash table is not fully initialized before the shrinker is registered. On weakly-ordered architectures such as arm64 and ppc , a shrinker scan can observe the drc_hashsize before the bucket list heads are initialized, r...

kernel: ipvlan: Make the addrs_lock be per port

A race condition vulnerability was found in the Linux kernel's ipvlan driver. The per-device addrslock was incorrectly used instead of a per-port lock, and some code paths ipvlanopen/ipvlanclose failed to acquire the lock entirely. For IPv6 address changes that don't require RTNL lock, concurrent...
