- Summary
- Updated kernel packages fix security vulnerabilities
- Details
-
This kernel update is based on upstream 5.10.12 and fixes at least the following security issues:
fs/nfsd/nfs3xdr.c in the Linux kernel through 5.10.8, when there is an NFS export of a subdirectory of a filesystem, allows remote attackers to traverse to other parts of the filesystem via READDIRPLUS (CVE-2021-3178).
An issue was discovered in the Linux kernel through 5.10.11. PI futexes have a kernel stack use-after-free during fault handling, allowing local users to execute code in the kernel (CVE-2021-3347).
nbd_add_socket in drivers/block/nbd.c in the Linux kernel through 5.10.12 has an ndb_queue_rq use-after-free that could be triggered by local attackers (with access to the nbd device) via an I/O request at a certain point during device setup (CVE-2021-3348).
It also adds the following fixes:
- ALSA: hda: Add Cometlake-R PCI ID
- ALSA: hda: Add AlderLake-P PCI ID and HDMI codec vid
- ALSA: hda/via: Apply the workaround generically for Clevo machines
- ASoC: AMD Renoir - refine DMI entries for some Lenovo products
- crypto: arm64/sha - add missing module aliases
- drm/amdgpu: Add Missing Sienna Cichlid DID
- drm/gpu/nouveau/dispnv50: Restore pushing of all data
- fix and re-enamble 3rdparty rtl8821ce driver (mga#28150)
- iwlwifi: provide gso_type to GSO packets (fixes upload speed regression)
For other upstream fixes, see the referenced changelogs.
