Summary
It was discovered that the i.MX clock driver in the Linux kernel did not
properly handle certain memory allocation failure conditions, leading to a
null pointer dereference vulnerability. A local attacker could possibly use
this to cause a denial of service (system crash). (CVE-2022-3114)
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
