<p>An update that solves four vulnerabilities can now be installed.</p>
<h2>Description:</h2>
<p>This update for the Linux Kernel 5.14.21-150500_55_12 fixes several issues.</p>
<p>The following security issues were fixed:</p>
<ul>
<li>CVE-2023-6531: Fixed a use-after-free flaw due to a race problem in the unix garbage collector's deletion of SKB races with unix_stream_read_generic()on the socket that the SKB is queued on (bsc#1218487).</li>
<li>CVE-2023-46813: Fixed a local privilege escalation with user-space programs that have access to MMIO regions (bsc#1216898).</li>
<li>CVE-2023-39191: Fixed a lack of validation of dynamic pointers within user-supplied eBPF programs that may have allowed an attacker with CAP_BPF privileges to escalate privileges and execute arbitrary code. (bsc#1215863)</li>
<li>CVE-2023-51779: Fixed a use-after-free because of a bt_sock_ioctl race condition in bt_sock_recvmsg (bsc#1218610).</li>
