========================================================================== Ubuntu Security Notice USN-6704-3 March 25, 2024
linux-oracle, linux-oracle-5.15 vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 22.04 LTS - Ubuntu 20.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-oracle: Linux kernel for Oracle Cloud systems - linux-oracle-5.15: Linux kernel for Oracle Cloud systems Details: It was discovered that the NVIDIA Tegra XUSB pad controller driver in the Linux kernel did not properly handle return values in certain error conditions. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-23000) Quentin Minster discovered that the KSMBD implementation in the Linux kernel did not properly handle session setup requests. A remote attacker could possibly use this to cause a denial of service (memory exhaustion). (CVE-2023-32247) Lonial Con discovered that the netfilter subsystem in the Linux kernel did not properly handle element deactivation in certain cases, leading to 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-2024-1085) Notselwyn discovered that the netfilter subsystem in the Linux kernel did not properly handle verdict parameters in certain cases, leading to 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-2024-1086) It was discovered that a race condition existed in the SCSI Emulex LightPulse Fibre Channel driver in the Linux kernel when unregistering FCF and re-scanning an HBA FCF table, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2024-24855) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 22.04 LTS: linux-image-5.15.0-1054-oracle 5.15.0-1054.60 linux-image-oracle-lts-22.04 5.15.0.1054.50 Ubuntu 20.04 LTS: linux-image-5.15.0-1054-oracle 5.15.0-1054.60~20.04.1 linux-image-oracle 5.15.0.1054.60~20.04.1 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.
