CVE-2024-26780 af_unix: Fix task hung while purging oob_skb in GC.

In the Linux kernel, the following vulnerability has been resolved: afunix: Fix task hung while purging oobskb in GC. syzbot reported a task hung; at the same time, GC was looping infinitely in listforeachentrysafe for OOB skb. 0 syzbot demonstrated that the listforeachentrysafe was not actually...

CVE-2024-26780

CVE-2024-26780 | Linux kernel (af_unix) — The vulnerability centers on a task hang during purging oob_skb in GC. The root cause is that list_for_each_entry_safe() is not actually safe when a single skb has references from multiple sockets; freeing such an skb can unlink current and next sockets i...
