| Description: | Summary:
The remote host is missing an update for the 'linux-gcp-5.15' package(s) announced via the USN-7459-2 advisory.
Vulnerability Insight:
Jann Horn discovered that the watch_queue event notification subsystem in
the Linux kernel contained an out-of-bounds write vulnerability. A local
attacker could use this to cause a denial of service (system crash) or
escalate their privileges. (CVE-2022-0995)
