Vulnerability description

The vulnerability allows a local attacker to gain elevated privileges or cause DoS condition on the target system.

The weakness exists due to race condition in fs/timerfd.c in the Linux kernel. A local attacker can use simultaneous file-descriptor operations, leverage improper might_cancel queueing, trigger list corruption or use-after-free and cause the service to crash or execute arbitrary code with root privileges.

Remediation

Update to version 4.10.15.
