RHSA-2022:1550: Important: kernel security and bug fix update
Published Apr 26, 2022
·Updated
The kernel packages contain the Linux kernel, the core of any Linux operating system.Security Fix(es): kernel: use-after-free in RDMA listen() (CVE-2021-4028) kernel: heap out of bounds write in nfdupnetdev.c (CVE-2022-25636) 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.Bug Fix(es): Backport DFS fixes from upstream (BZ#2056329) [RHEL8.5] lpfc driver often fails to detect storage directly connected to Broadcom FC HBA (BZ#2058193) nfreinject calls nfqueueentryfree on an already freed entry->state (BZ#2061446) gfs2 blocking in gdlmlock (BZ#2069750)
