kernel: macvlan: fix error recovery in macvlan_common_newlink()

A use-after-free vulnerability was found in the macvlan driver. When creating a macvlan interface in source mode fails after the source MAC has been added to the hash table e.g., due to an invalid interface name, the hash entry still references the freed netdevice structure. Subsequent packets...

CVE-2026-31409

A flaw was found in ksmbd, a component of the Linux kernel. This vulnerability occurs when a multichannel Server Message Block SMB2 session setup request, specifically one with a binding flag, fails. Due to an error in handling this failure, ksmbd incorrectly retains a binding state for the...

kernel: Linux kernel (net/mlx5): Use-after-free in ECVF vports unload leads to denial of service

A flaw was found in the Linux kernel's net/mlx5 component. A local user could exploit a use-after-free vulnerability during the shutdown process when embedded chip virtual function ECVF vports are unloaded. This occurs because the vport access control list ACL ingress table is not properly...
