Debian Security Advisory DSA-4892-1 addresses significant patches for various kernel security flaws, specifically including potential escalation of privilege vulnerabilities.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-snapdragon: Linux kernel for Qualcomm Snapdragon processors

Details:

It was discovered that the Traffic-Control Index (TCINDEX) implementation

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-2023-1281)

It was discovered that the System V IPC implementation in the Linux kernel

did not properly handle large shared memory counts. A local attacker could

use this to cause a denial of service (memory exhaustion). (CVE-2021-3669)

It was discovered that a use-after-free vulnerability existed in the SGI

GRU driver in the Linux kernel. A local attacker could possibly use this to

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

code. (CVE-2022-3424)

Ziming Zhang discovered that the VMware Virtual GPU DRM driver in the Linux

kerne...

Update Instructions

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

Ubuntu 18.04 LTS:
   linux-image-4.15.0-1148-snapdragon  4.15.0-1148.158
   linux-image-snapdragon          4.15.0.1148.147

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.
