RHSA-2023:1221: Important: kernel security, bug fix, and enhancement update
First published: Tue Mar 14 2023(Updated: )
The kernel packages contain the Linux kernel, the core of any Linux operating system.<br>The following packages have been upgraded to a later upstream version: kernel (4.18.0). (BZ#2165648)<br>Security Fix(es):<br><li> kernel: use-after-free caused by l2cap_reassemble_sdu() in net/bluetooth/l2cap_core.c (CVE-2022-3564)</li> <li> kernel: stack overflow in do_proc_dointvec and proc_skip_spaces (CVE-2022-4378)</li> <li> kernel: net: CPU soft lockup in TC mirred egress-to-ingress action (CVE-2022-4269)</li> For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.<br>Bug Fix(es):<br><li> RHEL 8.7 - Outputs of lsmem, lparstat, numactl and /proc/meminfo show wrong value of memory when LMB size is set to 4GB. (BZ#2140092)</li> <li> RHEL8.4 - boot: Add secure boot trailer (BZ#2151532)</li> <li> Concurrent reading of /proc/cpuinfo by multiple tasks causes soft lockup (BZ#2154441)</li> <li> GSS: OCP 4.10.30 node crash after ODF upgrade : unable to handle kernel NULL pointer dereference at 0000000000000000 : ceph_get_snap_realm+0x68/0xa0 [ceph] (BZ#2155799)</li> <li> cgroup: Backport cgroup_mutex performance patches (BZ#2160165)</li> <li> Redhat OpenShift: Error downloading big ZIP files inside pod on power OCP and pod getting restarted (BZ#2160223)</li> <li> i40e/iavf: VF reset task fails "Never saw reset" with 5 second timeout per VF (BZ#2160462)</li> <li> panic in fib6_rule_suppress+0x22 with custom xdp prog involved in (BZ#2167606)</li>
