A race condition in the IPV6_2292PKTOPTIONS socket option handler allows a malicious application to modify freed memory, potentially leading to remote code execution. With a CVSS score of 8.1 (HIGH), this vulnerability is remotely exploitable with high impact on confidentiality, integrity, and availability, though attack complexity is also high. While not observed in active exploitation, a Metasploit module exists for privilege escalation, indicating exploitability. Community discussion and media coverage are minimal.
