UBUNTU-CVE-2024-26780

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...

DEBIAN-CVE-2024-26732

In the Linux kernel, the following vulnerability has been resolved: net: implement lockless setsockoptSOPEEKOFF syzbot reported a lockdep violation 1 involving afunix support of SOPEEKOFF. Since SOPEEKOFF is inherently not thread safe it uses a per-socket skpeekoff field, there is really no point...

kernel: use after free in unix_stream_sendpage

A use-after-free flaw was found in the Linux kernel's afunix component that allows local privilege escalation. The unixstreamsendpage function tries to add data to the last skb in the peer's recv queue without locking the queue. This issue leads to a race condition where the unixstreamsendpage...
