An update that solves two vulnerabilities can now be installed.

Description:

The SUSE Linux Enterprise 15 SP3 kernel was updated to receive various security and bugfixes.

Security issues fixed:

• CVE-2021-22555: A heap out-of-bounds write was discovered in net/netfilter/x_tables.c (bnc#1188116).
• CVE-2021-33909: Extremely large seq buffer allocations in seq_file could lead to buffer underruns and code execution (bsc#1188062).

The following non-security bugs were fixed:

• usb: dwc3: Fix debugfs creation flow (git-fixes).

Special Instructions and Notes:

• Please reboot the system after installing this update.

Patch Instructions:

To install this SUSE update use the SUSE recommended installation methods like YaST online_update or "zypper patch".
Alternatively you can run the command listed for your product:

• openSUSE Leap 15.3
  zypper in -t patch SUSE-2021-2415=1
• Basesystem Module 15-SP3
  zypper in -t patch SUSE-SLE-Module-Basesystem-15-SP3-2021-2415=1
• Development Tools Module 15-SP3
  zypper in -t patch SUSE-SLE-Module-Development-Tools-15-SP3-2021-2415=1
• Legacy Module 15-SP3
