The SUSE Linux Enterprise 15 SP3 kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2021-3640: Fixed a Use-After-Free vulnerability in function sco_sock_sendmsg() in the bluetooth stack (bsc#1188172). - CVE-2021-3653: Missing validation of the `int_ctl` VMCB field and allows a malicious L1 guest to enable AVIC support for the L2 guest. (bsc#1189399). - CVE-2021-3656: Missing validation of the the `virt_ext` VMCB field and allows a malicious L1 guest to disable both VMLOAD/VMSAVE intercepts and VLS for the L2 guest (bsc#1189400). - CVE-2021-3679: A lack of CPU resource in tracing module functionality was found in the way user uses trace ring buffer in a specific way.
