USN-6895-1: Linux kernel vulnerabilities

Published Jul 12, 2024
·
Updated

It was discovered that the ATA over Ethernet (AoE) driver in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2023-6270) It was discovered that the HugeTLB file system component of the Linux Kernel contained a NULL pointer dereference vulnerability. A privileged attacker could possibly use this to to cause a denial of service. (CVE-2024-0841) It was discovered that the Open vSwitch implementation in the Linux kernel could overflow its stack during recursive action operations under certain conditions. A local attacker could use this to cause a denial of service (system crash). (CVE-2024-1151) Gui-Dong Han discovered that the software RAID driver in the Linux kernel contained a race condition, leading to an integer overflow vulnerability. A privileged attacker could possibly use this to cause a denial of service (system crash). (CVE-2024-23307) Bai Jiaju discovered that the Xceive XC4000 silicon tuner device driver in the Linux kernel contained a race condition, leading to an integer overflow vulnerability. An attacker could possibly use this to cause a denial of service (system crash). (CVE-2024-24861) 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:
