USN-6724-1: Linux kernel vulnerabilities
Pratyush Yadav discovered that the Xen network backend implementation in the Linux kernel did not properly handle zero length data request, leading to a null pointer dereference vulnerability. An attacker in a guest VM could possibly use this to cause a denial of service (host domain crash). (CVE-2023-46838) It was discovered that the Habana's AI Processors driver in the Linux kernel did not properly initialize certain data structures before passing them to user space. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2023-50431) It was discovered that the device mapper driver in the Linux kernel did not properly validate target size during certain memory allocations. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-52429, CVE-2024-23851) It was discovered that the CIFS network file system implementation in the Linux kernel did not properly validate certain SMB messages, leading to an out-of-bounds read vulnerability. An attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2023-6610) Yang Chaoming discovered that the KSMBD implementation in the Linux kernel did not properly validate request buffer sizes, leading to an out-of-bounds read vulnerability. An attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2024-22705) Chenyuan Yang discovered that the btrfs file system in the Linux kernel did not properly handle read operations on newly created subvolumes in certain conditions. A local attacker could use this to cause a denial of service (system crash). (CVE-2024-23850) 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:
