CVE-2026-97963

The Linux kernel contains a vulnerability in the stmmac driver where the ptp_lock (an rwlock) is only initialized during __stmmac_open(). Because the lock is accessed by stmmac_get_time() during tc_taprio_configure() even when the interface is down and never opened, using the uninitialized lock r...

CVE-2026-97962

The Linux kernel contains a vulnerability in the net/mlx5e driver where the representor vnic devlink health reporter is created and destroyed along a path not serialized by the devlink instance lock. This lack of serialization triggers a devl_assert_locked() splat during driver unbind. The issue ...

CVE-2026-97959

In the Linux kernel, the following vulnerability has been resolved: net/sched: clsroute: free emptied bucket on filter move route4change can move an existing filter to a different top-level bucket: route4setparms recomputes the handle from TCAROUTE4TO/ FROM/IIF, and the handle-mismatch check is...

CVE-2026-97959 net/sched: cls_route: free emptied bucket on filter move

In the Linux kernel, the following vulnerability has been resolved: net/sched: clsroute: free emptied bucket on filter move route4change can move an existing filter to a different top-level bucket: route4setparms recomputes the handle from TCAROUTE4TO/ FROM/IIF, and the handle-mismatch check is...

CVE-2026-97959

The Linux kernel contains a memory leak vulnerability in the net/sched: cls_route component. When an existing filter is moved to a different top-level bucket via route4_change, the filter is unlinked from the old bucket, but the bucket is never freed. This results in stale empty buckets remaining...
