Summary
Important: kernel security and bug fix update
Details

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

  • kernel: powerpc: KVM guest OS users can cause host OS memory corruption (CVE-2021-37576)

  • kernel: slab-out-of-bounds access in xdr_set_page_base() in net/sunrpc/xdr.c (CVE-2021-38201)

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):

  • Update Broadcom Emulex lpfc driver for AlmaLinux8.5 with bug fixes (BZ#1948608)

  • cyclictest shows >50us latency when guest enters idle (RT guest with 18 RT vCPUs) (BZ#1981336)

  • xfrm: backports from upstream (BZ#1981840)

  • A task is stuck waiting for the completion of the vmci_resouce releasing upon the balloon reset. (BZ#1982042)

  • [mlx5] backport driver bits of net: zero-initialize tc skb extension on allocation (BZ#1982220)

  • Kernel cannot kill a process doing compaction for hugepage allocation (BZ#1984085)

  • AlmaLinux8.4 Nightly[0108] - [P10] [Regression] Kdump failed on AlmaLinux8.4 on SAN disk via flavafish adapter (qla2xxx/HPT/Radix) (BZ#1986156)

  • [AlmaLinux8.5] scheduler updates and fixes (BZ#1987296)

  • AlmaLinux 8.3 using FCOE via a FastLinQ QL45000 card will not manually scan in LUN from Target_id's over 8 (BZ#1989097)

  • fixes for oopses in security mitigation runtime code patching (BZ#1989174)

  • act mirred doesn't scrub packets when sending them to ingress (BZ#1992226)

  • HPE: Cannot install 8.4 using the DVD presented to the iLO (BZ#1993894)

  • NFS client hangs on share listing when server side readdir verifiers are implemented (BZ#1993895)

  • SNO: The load is extremely high (~870) when pao is added and a profile is applied. (BZ#1994879)

  • timeout value of conntrack entry with TCP ESTABLISHED status is too short (BZ#1995554)

  • Increase the default value for flowtable offload timeouts (BZ#1995555)

  • ice/iavf driver stop responding (BZ#1997534)

  • [FJ8.4 Bug]: [REG] Some files in /proc/sys/user show wrong data (BZ#1998002)
