Summary
kernel security update
Details

he Linux Kernel, the operating system core itself.

Security Fix(es):

A flaw use-after-free in function scosocksendmsg() of the Linux kernel HCI subsystem was found in the way user calls ioct UFFDIOREGISTER or other way triggers race condition of the call scoconndel() together with the call scosock_sendmsg() with the expected controllable faulting memory page. A privileged local user could use this flaw to crash the system or escalate their privileges on the system.(CVE-2021-3640)
