Summary

linux-realtime vulnerability

Details

It was discovered that the AF_UNIX socket garbage collection implementation in Ubuntu Noble's 6.8 kernel did not properly handle out-of-band (OOB) messages, leading to a use-after-free vulnerability. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
