Publication date

7 May 2024

Overview

Several security issues were fixed in the Linux kernel.

Packages

Details

Chenyuan Yang discovered that the RDS Protocol implementation in the Linux
kernel contained an out-of-bounds read vulnerability. An attacker could use
this to possibly cause a denial of service (system crash). (CVE-2024-23849)

Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:

  • ARM64 architecture;
  • PowerPC architecture;
  • S390 architecture;
  • Block layer subsystem;
  • Android drivers;
  • Hardware random number generator core;
  • GPU drivers;
  • Hardware monitoring drivers;
  • I2C subsystem;
  • IIO Magnetometer sensors drivers;
  • InfiniBand drivers;
  • Network drivers;
  • PCI driver for MicroSemi Switchtec;
  • PHY drivers;
  • Ceph distributed file system;
  • Ext4 file...

Update instructions

After a standard system update you need to reboot your computer to make all the necessary changes.

Learn more about how to get the fixes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.

The problem can be corrected by updating your system to the following package versions:
