AZL-48759 CVE-2024-36972 affecting package kernel for versions less than 6.6.64.2-9

In the Linux kernel, the following vulnerability has been resolved: afunix: Update unixsksk-oobskb under skreceivequeue lock. Billy Jheng Bing-Jhong reported a race between unixgc and queueoob. unixgc tries to garbage-collect closed inflight sockets, and then if the socket has MSGOOB in...

CVE-2024-35970

A vulnerability was found in the Linux kernel's Unix domain socket afunix implementation, where stale Out-of-Band OOB data is not cleared from the receive queue. This issue arises when OOB data is dequeued but the associated oobskb is not cleared, leading to incorrect behavior in subsequent recv...

SUSE CVE-2024-26676

In the Linux kernel, the following vulnerability has been resolved: afunix: Call kfreeskb for dead unixsk-oobskb in GC. syzbot reported a warning 0 in unixgc with a repro, which creates a socketpair and sends one socket's fd to itself using the peer. socketpairAFUNIX, SOCKSTREAM, 0, 3, 4 = 0...

CVE-2024-26780

A flaw was found in the Linux kernel's afunix subsystem where tasks could hang while purging out-of-bounds sockets during garbage collection. This issue could potentially lead to system instability. Mitigation Mitigation for this issue is either not available or the currently available options do...
