Summary
kernel security update
Details

The Linux Kernel, the operating system core itself.

Security Fix(es):

A read-after-free memory flaw was found in the Linux kernel s garbage collection for Unix domain socket file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race condition. This flaw allows a local user to crash the system or escalate their privileges on the system.(CVE-2021-4083)
