kernel: GC's deletion of an SKB races with unix_stream_read_generic() leading to UAF

A use-after-free flaw was found in the Linux Kernel due to a race problem in the unix garbage collector's deletion of SKB races with unixstreamreadgeneric on the socket that the SKB is queued on...

kernel: Bluetooth: L2CAP: Fix potential user-after-free

A use-after-free flaw was identified in the Linux kernel’s Bluetooth L2CAP implementation. In certain conditions, when allocating a socket buffer via allocskb, the kernel may release and later reacquire the channel lock; if the channel is disconnected in the meantime, a subsequent reference to th...
