Mageia 2021-0085: kernel-linus security update
Summary
This kernel-linus update is based on upstream 5.10.14 and fixes atleast
the following security issues:
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).
A local privilege escalation was discovered in the Linux kernel before
5.10.13. Multiple race conditions in the AF_VSOCK implementation are
caused by wrong locking in net/vmw_vsock/af_vsock.c (CVE-2021-26708).
It also adds the following fixes:
- make CONNECTOR builtin to enable PROC_EVENTS (mga#28312)
For other upstream fixes, see the referenced changelogs.
