(CVE-2024-26921, CVE-2023-52629, CVE-2024-26680, CVE-2024-26830,
CVE-2024-39484, CVE-2024-39292, CVE-2024-36901, CVE-2023-52760)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 20.04 LTS
linux-image-5.15.0-1066-oracle 5.15.0-1066.72~20.04.1
linux-image-oracle 5.15.0.1066.72~20.04.1
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.
