Linux kernel AF_UNIX race condition
| linux-afunix-race-condition (18230) |  High Risk |
Description:
Linux kernel is vulnerable to a race condition, caused by a vulnerability in the AF_UNIX address family. A local attacker could exploit this vulnerability to modify arbitrary kernel memory and gain elevated privileges or possibly execute arbitrary code on the system.
