Linux kernel uselib privilege escalation
| linux-uselib-gain-privileges (18800) |  High Risk |
Description:
Linux kernel could allow a local attacker to gain elevated privileges on the system, caused by a vulnerability in the uselib Linux binary format loaders functions. A local attacker could exploit this vulnerability to gain root privileges on the system.
