In the Linux kernel, the following vulnerability has been resolved: net: bridge: vlan: fix memory leak in __allowed_ingress When using per-vlan state, if vlan snooping and stats are disabled, untagged or priority-tagged ingress frame will go to check pvid state. If the port state is forwarding and the pvid state is not learning/forwarding, untagged or priority-tagged frame will be dropped but skb memory is not freed. Should free skb when __allowed_ingress returns false. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: net: bridge: vlan: corrige la pérdida de memoria en __allowed_ingress Cuando se usa el estado por VLAN, si la vigilancia de VLAN y las estadísticas están deshabilitadas, el marco de ingreso sin etiquetar o con etiqueta de prioridad irá a verificar pvid estado. • https://git.kernel.org/stable/c/a580c76d534c7360ba68042b19cb255e8420e987 https://git.kernel.org/stable/c/446ff1fc37c74093e81db40811a07b5a19f1d797 https://git.kernel.org/stable/c/c5e216e880fa6f2cd9d4a6541269377657163098 https://git.kernel.org/stable/c/14be8d448fca6fe7b2a413831eedd55aef6c6511 https://git.kernel.org/stable/c/fd20d9738395cf8e27d0a17eba34169699fccdff • CWE-400: Uncontrolled Resource Consumption •

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix handling of wrong devices during bond netevent Current implementation of bond netevent handler only check if the handled netdev is VF representor and it missing a check if the VF representor is on the same phys device of the bond handling the netevent. Fix by adding the missing check and optimizing the check if the netdev is VF representor so it will not access uninitialized private data and crashes.
