The SUSE Linux Enterprise 15 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 (XSA-365 bsc#1181843). - CVE-2021-26931: Fixed an issue where Linux kernel was treating grant mapping errors as bugs (XSA-362 bsc#1181753). - CVE-2021-26932: Fixed improper error handling issues in Linux grant mapping (XSA-361 bsc#1181747). by remote attackers to read or write files via directory traversal in an XCOPY request (bsc#178372). - 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 (bsc#1179660, bsc#1179428).
The following non-security bugs were fixed:
- kernel-{binary,source}.spec.in: do not create loop symlinks (bsc#1179082) - kernel-source.spec: Fix build with rpm 4.16 (boo#1179015). - rpm/kernel-binary.spec.in: avoid using barewords (bsc#1179014) - rpm/kernel-binary.spec.in: avoid using more barewords (bsc#1179014) %split_extra still contained two. - rpm/kernel-binary.spec.in: Fix compressed module handling for in-tree KMP (jsc#SLE-10886) The in-tree KMP that is built with SLE kernels have a different scriptlet that is embedded in kernel-binary.spec.in rather than *.sh files. - rpm/kernel-binary.spec.in: use grep -E instead of egrep (bsc#1179045) egrep is only a deprecated bash wrapper for 'grep -E'. So use the latter instead. - rpm/kernel-module-subpackage: make Group tag optional (bsc#1163592) - rpm/kernel-obs-build.spec.in: Add -q option to modprobe calls (bsc#1178401) - rpm/kernel-{source,binary}.spec: do not include ghost symlinks (boo#1179082). - rpm/mkspec: do not build kernel-obs-build on x86_32 We want to use 64bit kernel due to various bugs (bsc#1178762 to name one). - rpm/post.sh: Avoid purge-kernel for the first installed kernel (bsc#1180058) - xen/netback: avoid race in xenvif_rx_ring_slots_available() (bsc#1065600). - xen/netback: fix spurious event detection for common event case (bsc#1182175).
