Summary
kernel security update
Details

The Linux Kernel, the operating system core itself.

Security Fix(es):

A flaw was found in the Routing decision classifier in the Linux kernel s Traffic Control networking subsystem in the way it handled changing of classification filters, leading to a use-after-free condition. This flaw allows unprivileged local users to escalate their privileges on the system. The highest threat from this vulnerability is confidentiality, integrity, as well as system availability.(CVE-2021-3715)
