USN-6496-1: Linux kernel vulnerabilities

Publication date

21 November 2023

Overview

Several security issues were fixed in the Linux kernel.

Releases

Packages

Details

Ivan D Barrera, Christopher Bednarz, Mustafa Ismail, and Shiraz Saleem
discovered that the InfiniBand RDMA driver in the Linux kernel did not
properly check for zero-length STAG or MR registration. A remote attacker
could possibly use this to execute arbitrary code. (CVE-2023-25775)

Yu Hao discovered that the UBI driver in the Linux kernel did not properly
check for MTD with zero erasesize during device attachment. A local
privileged attacker could use this to cause a denial of service (system
crash). (CVE-2023-31085)

Manfred Rudigier discovered that the Intel(R) PCI-Express Gigabit (igb)
Ethernet driver in the Linux kernel did not properly validate received
frames that are larger than the set MTU size, leading to a buffer overflow
vulnerability. An attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary...

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:
