linux-oracle-5.15 vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 20.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

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

Details:

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:
   - SuperH RISC architecture;
   - User-Mode Linux (UML);
   - MMC subsystem;
   - Network drivers;
   - GFS2 file system;
   - IPv4 networking;
   - IPv6 networking;
(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.
