CVE-2024-26732

CVE-2024-26732 affects the Linux kernel where SO_PEEK_OFF for sockets could cause a lockdep violation in af_unix, due to per-socket uio lock usage. The vulnerability arises because SO_PEEK_OFF was previously protected by kernel locks; a patch implemented lockless behavior for setsockopt(SO_PEEK_O...

CVE-2024-26732 net: implement lockless setsockopt(SO_PEEK_OFF)

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...
