Dist Ubuntu Esm H88
Several critical security issues in the Linux kernel were resolved in Ubuntu Security Notice USN-7391-1 to mitigate risks.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux: Linux kernel

- linux-hwe-5.4: Linux hardware enablement (HWE) kernel

Details:

Chenyuan Yang discovered that the CEC driver driver in the Linux kernel

contained a use-after-free vulnerability. A local attacker could use this

to cause a denial of service (system crash) or possibly execute arbitrary

code. (CVE-2024-23848)

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:

- PowerPC architecture;

- S390 architecture;

- SuperH RISC architecture;

- User-Mode Linux (UML);

- x86 architecture;

- Cryptographic API;

- Virtio block driver;

- Data acquisition framework and drivers;

- Hardware crypto device drivers;

- DMA engine subsystem;

- EDAC drivers;

- ARM SCPI message protocol;

- GPIO subsystem;

- GPU d...

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

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.
