  script_tag(name:"insight", value:"This kernel update is based on upstream 5.10.56 and fixes at least the
following security issues:

In the Linux kernel through 5.13.7, an unprivileged BPF program can
obtain sensitive information from kernel memory via a Speculative Store
Bypass side-channel attack because the protection mechanism neglects the
possibility of uninitialized memory locations on the BPF stack
(CVE-2021-34556).

In the Linux kernel through 5.13.7, an unprivileged BPF program can
obtain sensitive information from kernel memory via a Speculative Store
Bypass side-channel attack because a certain preempting store operation
does not necessarily occur before a store operation that has an
attacker-controlled value (CVE-2021-35477).

Other fixes in this update:
- btrfs: fix lost inode on log replay after mix of fsync, rename and
 inode eviction
- btrfs: fix race causing unnecessary inode logging during link and rename
- watchdog: iTCO_wdt: Fix detection of SMI-off case (fixes sporadic reboots
 on some systems)
- Revert 'ACPICA: Fix memory leak caused by _CID repair function', fixing
 boot failures on some systems
- fix another ACPI issue causing some systems to boot slowly or not at all
 after kernel 5.10.50
- revert: 'scsi: sr: Return appropriate error code when disk is ejected'
 (fixes DVD opening on resume from suspend or standby, mga #29262)
- Revert 'usb: renesas-xhci: Fix handling of unknown ROM state'
 (fixes renesas usb pci stopped working, mga #29285)
- Revert 'drm/i915: Propagate errors on awaiting already signaled fences'
 and 'drm/i915/gem: Asynchronous cmdparser' (fixes an issue where an
 app hang can cause X server to hang)

For other upstream fixes, see the referenced changelogs.");
