Description
A vulnerability in the Linux kernel's BPF subsystem caused invalid memory access when the update_effective_progs function failed due to fault injection. This led to the use of a dummy BPF program pointer, which triggered invalid access to program statistics during softirq processing. The issue was fixed by skipping stats updates when the stats pointer is NULL.
