Comment 2 Thomas Backlund 2021-07-21 10:42:03 CEST 
Advisory, added to svn:

type: security
subject: Updated kernel-linus packages fix security vulnerabilities
CVE:
 - CVE-2021-3609
 - CVE-2021-33909
src:
  8:
   core:
     - kernel-linus-5.10.52-1.mga8
description: |
  This kernel-linus update is based on upstream 5.10.52 and fixes atleast
  the following security issues:

  There is a race condition in net/can/bcm.c that can lead to local
  privilege escalation to root (CVE-2021-3609).

  fs/seq_file.c in the Linux kernel 3.16 through 5.13.x before 5.13.4 does
  not properly restrict seq buffer allocations, leading to an integer
  overflow, an Out-of-bounds Write, and escalation to root by an unprivileged
  user (CVE-2021-33909).

  For other upstream fixes, see the referenced changelogs.
