kernel: net/sched: act_ct: fix skb leak and crash on ooo frags

A memory leak flaw and potential kernel crash were found in the Linux kernel’s Conntrack module. This issue occurs when Conntrack is being used by a local user for a specific configuration, and both fragmented packets are received remotely and out of order. This flaw allows a local or remote user...

kernel: net: bridge: xmit: make sure we have at least eth header len bytes

A vulnerability was found in the Linux kernel in the net: bridge component, where the xmit function in the bridge device could trigger an uninitialized value error if a short skb less than the required ETHHLEN bytes is sent. This condition could cause unexpected behavior due to insufficient check...
