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...

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...

CVE-2024-26750

CVE-2024-26750 affects the Linux kernel. The vulnerability was in af_unix garbage collection: a self-referencing oob_skb/FD scenario could cause __unix_gc() to hang due to a loop that fails to purge inflight sockets. The fix drops the oob_skb reference before purging the queue, allowing __skb_que...
