USN-6957-1: Linux kernel (Oracle) vulnerabilities

Releases

• Ubuntu 20.04 LTS

Packages

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

Details

Benedict Schlüter, Supraja Sridhara, Andrin Bertschi, and Shweta Shinde
discovered that an untrusted hypervisor could inject malicious #VC
interrupts and compromise the security guarantees of AMD SEV-SNP. This flaw
is known as WeSee. A local attacker in control of the hypervisor could use
this to expose sensitive information or possibly execute arbitrary code in
the trusted execution environment. (CVE-2024-25742)

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:

• ARM32 architecture;
• ARM64 architecture;
• Block layer subsystem;
• Bluetooth drivers;
• Clock framework and drivers;
• FireWire subsystem;
• GPU drivers;
• InfiniBand drivers;
• Multiple devices driver;
• EEPROM drivers;
• Network drivers;
• Pin controllers subsystem;
• Remote Processor subsystem;
• S/390 drivers;
• SCSI drivers;
• TTY drivers;
• 9P distributed file system;
• Network file system client;
• SMB network file system;
• Socket messages infrastructure;
• Dynamic debug library;
• Bluetooth subsystem;
• Networking core;
• IPv4 networking;
• IPv6 networking;
• Multipath TCP;
• Netfilter;
• NSH protocol;
• Phonet protocol;
• TIPC protocol;
• Wireless networking;
• Key management;
• ALSA framework;
• HD-audio driver;

Update instructions

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

Ubuntu 20.04

• linux-image-5.15.0-1065-oracle - 5.15.0-1065.71~20.04.1
• linux-image-oracle - 5.15.0.1065.71~20.04.1

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.
