========================================================================== Ubuntu Security Notice USN-6686-2 March 13, 2024
linux-lowlatency, linux-raspi vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 22.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-lowlatency: Linux low latency kernel - linux-raspi: Linux kernel for Raspberry Pi systems Details: It was discovered that the DesignWare USB3 for Qualcomm SoCs driver in the Linux kernel did not properly handle certain error conditions during device registration. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2023-22995) It was discovered that a race condition existed in the Cypress touchscreen driver in the Linux kernel during device removal, leading to a use-after- free vulnerability. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-4134) 黄思聪 discovered that the NFC Controller Interface (NCI) implementation in the Linux kernel did not properly handle certain memory allocation failure conditions, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-46343) It was discovered that the io_uring subsystem in the Linux kernel contained a race condition, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-46862) It was discovered that a race condition existed in the Bluetooth subsystem of the Linux kernel, 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-2023-51779) It was discovered that a race condition existed in the Rose X.25 protocol implementation in the Linux kernel, 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-2023-51782) Alon Zahavi discovered that the NVMe-oF/TCP subsystem of the Linux kernel did not properly handle connect command payloads in certain situations, leading to an out-of-bounds read vulnerability. A remote attacker could use this to expose sensitive information (kernel memory). (CVE-2023-6121) It was discovered that the VirtIO subsystem in the Linux kernel did not properly initialize memory in some situations. A local attacker could use this to possibly expose sensitive information (kernel memory). (CVE-2024-0340) Dan Carpenter discovered that the netfilter subsystem in the Linux kernel did not store data in properly sized memory locations. A local user could use this to cause a denial of service (system crash). (CVE-2024-0607) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 22.04 LTS: linux-image-5.15.0-100-lowlatency 5.15.0-100.110 linux-image-5.15.0-100-lowlatency-64k 5.15.0-100.110 linux-image-5.15.0-1048-raspi 5.15.0-1048.51 linux-image-lowlatency 5.15.0.100.96 linux-image-lowlatency-64k 5.15.0.100.96 linux-image-raspi 5.15.0.1048.46 linux-image-raspi-nolpae 5.15.0.1048.46 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.
