CVE-2026-43029

A flaw was found in the Linux kernel's Multipath TCP mptcp implementation. When an attacker sends data with MSGPEEK | MSGWAITALL flags, the system can enter a soft lockup state. This occurs because the skreceivequeue is not properly cleared, causing the system to continuously find available data...

SUSE CVE-2026-23394

In the Linux kernel, the following vulnerability has been resolved: afunix: Give up GC if MSGPEEK intervened. Igor Ushakov reported that GC purged the receive queue of an alive socket due to a race with MSGPEEK with a nice repro. This is the exact same issue previously fixed by commit cbcf01128d0...
