Notes

Title of the patch
Security update for the Linux Kernel (Live Patch 24 for SLE 15)
Description of the patch
This update for the Linux Kernel 4.12.14-150_72 fixes several issues. The following security issues were fixed: - CVE-2021-33200: Enforcing incorrect limits for pointer arithmetic operations by the BPF verifier could be abused to perform out-of-bounds reads and writes in kernel memory (bsc#1186484). - CVE-2021-33034: Fixed a use-after-free when destroying an hci_chan. This could lead to writing an arbitrary values (bsc#1186111). - CVE-2021-23134: A Use After Free vulnerability in nfc sockets allowed local attackers to elevate their privileges (bnc#1186060). - CVE-2021-32399: Fixed a race condition when removing the HCI controller (bnc#1184611).
