Dist Ubuntu Esm H88
Uncover vital security patches for Ubuntu 22.04 targeting various vulnerabilities that could lead to severe system instability.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-oem-6.0: Linux kernel for OEM systems

Details:

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

kernel contained an out-of-bounds write vulnerability. A local attacker

could use this to cause a denial of service (system crash).

(CVE-2022-36280)

Gerald Lee discovered that the USB Gadget file system implementation in the

Linux kernel contained a race condition, leading to a use-after-free

vulnerability in some situations. A local attacker could use this to cause

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

(CVE-2022-4382)

It was discovered that a memory leak existed in the SCTP protocol

implementation in the Linux kernel. A local attacker could use this to

Update Instructions

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

Ubuntu 22.04 LTS:
   linux-image-6.0.0-1014-oem      6.0.0-1014.14
   linux-image-oem-22.04b          6.0.0.1014.14

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.
