Security Fix(es):
-
kernel: race condition in net/can/bcm.c leads to local privilege escalation (CVE-2021-3609)
-
kernel: Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass RO checks (CVE-2021-22543)
-
kernel: out-of-bounds write in xt_compat_target_from_user() in net/netfilter/x_tables.c (CVE-2021-22555)
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.

Urgent: Missing dptf_power.ko module in AlmaLinux8 (BZ#1968381)
-
[mlx5] kdump over NFS fails: mlx5 driver gives error "Stop room 95 is bigger than the SQ size 64" (BZ#1969909)
-
BUG: unable to handle kernel NULL pointer dereference at 0000000000000000 in bluetooth hci_error_reset on intel-tigerlake-h01 (BZ#1972564)
-
Update CIFS to kernel 5.10 (BZ#1973637)
-
Backport "tick/nohz: Conditionally restart tick on idle exit" to AlmaLinux 8.5 (BZ#1978710)
-
Significant performance drop starting on kernel-4.18.0-277 visible on mmap benchmark (BZ#1980314)
-
