Description

A flaw was found in the Linux kernel's af_unix component. This use-after-free vulnerability arises from incorrect handling of Out-Of-Band (OOB) socket buffers (skb). A local attacker could exploit this by manipulating OOB data transmission and reception, causing the system to attempt to use memory that has already been freed. This could lead to a denial of service or potentially allow for privilege escalation.
