Ubuntu 20.04 LTS USN-7007-2 moderate: multiple kernel exploits

Scroller Ubuntu
Multiple security weaknesses patched in Ubuntu's Linux kernel, boosting system security and preventing possible attacks.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-ibm-5.15: Linux kernel for IBM cloud systems

- linux-oracle-5.15: Linux kernel for Oracle Cloud systems

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)

Chenyuan Yang discovered that the USB Gadget subsystem in the Linux kernel

did not properly check for the device to be enabled before writing. A local

attacker could possibly use this to cause a denial of service.

(CVE-2024-25741)

It was discovered that the JFS file system contained an out-of-bounds read

vulnerability when printing xattr debug information. A local attacker could

use this to cause a denial of service (system crash). (CVE-2024-40902)

Several security issues were discovered in the Linux kernel.

An attacker could possibly use the...

Update Instructions

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

Ubuntu 20.04 LTS
  linux-image-5.15.0-1062-ibm     5.15.0-1062.65~20.04.1
  linux-image-5.15.0-1067-oracle  5.15.0-1067.73~20.04.1
  linux-image-ibm                 5.15.0.1062.65~20.04.1
  linux-image-oracle              5.15.0.1067.73~20.04.1

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.
