USN-6865-1

Summary: linux, linux-aws, linux-kvm, linux-lts-xenial vulnerabilities

Details: It was discovered that the ext4 file system implementation in the Linux kernel did not properly validate data state on write operations. An attacker could use this to construct a malicious ext4 file system image that, when mounted, could cause a denial of service (system crash). (CVE-2021-33631) 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) Sander Wiebing, Alvise de Faveri Tron, Herbert Bos, and Cristiano Giuffrida discovered that the Linux kernel mitigations for the initial Branch History Injection vulnerability (CVE-2022-0001) were insufficient for Intel processors. A local attacker could potentially use this to expose sensitive information. (CVE-2024-2201) 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: - Block layer subsystem; - Hardware random number generator core; - Memory management; - Netfilter; (CVE-2024-26898, CVE-2023-52615, CVE-2024-26642, CVE-2024-26720)
