Title:RHSA-2021:3327: kernel security and bug fix update (Important)
Description:The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

  • kernel: out-of-bounds write in xt_compat_target_from_user() in net/netfilter/x_tables.c (CVE-2021-22555)

  • kernel: race condition for removal of the HCI controller (CVE-2021-32399)

  • kernel: powerpc: RTAS calls can be used to compromise kernel integrity (CVE-2020-27777)

  • kernel: Local privilege escalation due to incorrect BPF JIT branch displacement computation (CVE-2021-29154)

  • kernel: lack a full memory barrier upon the assignment of a new table value in net/netfilter/x_tables.c and include/linux/netfilter/x_tables.h may lead to DoS (CVE-2021-29650)

    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):

  • SAN Switch rebooted and caused (?) OpenStack compute node to reboot (BZ#1897576)

  • sysfs: cannot create duplicate filename '/class/mdio_bus/ixgbe-8100 (BZ#1915449)

  • XFS: read-only recovery does not update free space accounting in superblock (BZ#1921551)

  • The memcg_params field of kmem_cache struct contains an old slab address that is to small for the current size of memcg_limited_groups_array_size. (BZ#1951810)

  • Backport of upstream patch "net: Update window_clamp if SOCK_RCVBUF is set " into rhel-7 (BZ#1962196)

  • Kernel panic in init_cq_frag_buf (BZ#1962499)

  • futex: futex_requeue can potentially free the pi_state structure twice (BZ#1966856)

  • be_poll lockup doing ifenslave when netconsole using bond (BZ#1971744)

  • OCP4.7 nodes panic at BUG_ON in nf_nat_setup_info() (BZ#1972970)
