CVE-2023-6531

Summary

CVE-2023-6531 is a newly identified vulnerability in the Linux Kernel. This issue arises due to a race condition in the unix garbage collector, specifically during the deletion of SKB (Socket Buffer) races. The unix_stream_read_generic() function on the socket that the SKB is queued on is affected. A use-after-free flaw occurs when a memory block is freed but is still referenced, potentially leading to memory corruption or other unintended behavior. This vulnerability could allow an attacker to execute arbitrary code with kernel privileges, posing a serious security risk. System administrators are strongly encouraged to apply the appropriate patches as soon as possible to mitigate this threat.
