CyberRota Analysis

AI-Generated

The vulnerability in the unix socket implementation allows an unprivileged local user to exploit a use-after-free condition in the SOCK_STREAM receive path, potentially leading to privilege escalation. This issue arises from the failure to properly detach control messages from the socket buffer, resulting in freed data mbufs remaining accessible. Organizations with systems using unix sockets should prioritize patching this vulnerability to mitigate the risk of unauthorized privilege escalation.

Original NVD Description

The SOCK_STREAM receive path in the unix socket implementation failed to fully detach control messages from the socket buffer before processing them. Some error paths would free those messages, leaving freed data mbufs in the receive socket buffer. An unprivileged local user can exploit this use-after-free to escalate privileges.
