CVE-2026-80994

A flaw was found in the Open vSwitch component of the Linux kernel. A local attacker could exploit a use-after-free vulnerability during flow deletion. This occurs due to a race condition where the flow mask is freed prematurely, allowing subsequent operations to access deallocated memory...

CVE-2026-23173 net/mlx5e: TC, delete flows only for existing peers

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: TC, delete flows only for existing peers When deleting TC steering flows, iterate only over actual devcom peers instead of assuming all possible ports exist. This avoids touching non-existent peers and ensures cleanup ...

kernel: net/mlx5e: Check for NOT_READY flag state after locking

A race condition was found in the Linux kernel Mellanox mlx5 network driver's traffic control offload flow management. A local user with privileges to configure traffic control flower filters can trigger concurrent flow deletion operations where the NOTREADY flag is checked before acquiring the...
