[USN-4727-1] Linux kernel vulnerability

Severity High
Affected Packages 50
CVEs 1
Info Packages Vulnerabilities

The system could be made to crash or run programs as an administrator.

Alexander Popov discovered that multiple race conditions existed in the
AF_VSOCK implementation in the Linux kernel. A local attacker could use
this to cause a denial of service (system crash) or execute arbitrary code.
