The SUSE Linux Enterprise 12 SP4 kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2021-26930: Fixed an improper error handling in blkback"s grant mapping . - CVE-2021-26931: Fixed an issue where Linux kernel was treating grant mapping errors as bugs . - CVE-2021-26932: Fixed improper error handling issues in Linux grant mapping . by remote attackers to read or write files via directory traversal in an XCOPY request . - CVE-2020-29368,CVE-2020-29374: Fixed an issue in copy-on-write implementation which could have granted unintended write access because of a race condition in a THP mapcount check . The following non-security bugs were fixed: - cifs: check all path components in resolved dfs target . - cifs: fix check of tcon dfs in smb1 . - cifs: fix nodfs mount option . - cifs: introduce helper for finding referral server . - kernel-{binary,source}.spec.in: do not create loop symlinks - kernel-binary.spec: Add back initrd and image symlink ghosts to filelist . Fixes: 76a9256314c3 - kernel-source.spec: Fix build with rpm 4.16 . RPM_BUILD_ROOT is cleared before %%install. Do the unpack into RPM_BUILD_ROOT in %%install - rpm/kernel-binary.spec.in: avoid using barewords - rpm/kernel-binary.spec.in: avoid using more barewords %split_extra still contained two. - rpm/kernel-binary.spec.in: Fix compressed module handling for in-tree KMP - rpm/kernel-binary.spec.in: use grep -E instead of egrep egrep is only a deprecated bash wrapper for quot;grep -Equot;.
