USN-6866-1: Linux kernel vulnerabilities

Read Time:1 Minute, 26 Second

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;
– GPU drivers;
– AFS file system;
– Memory management;
– Netfilter;
(CVE-2024-26642, CVE-2024-26922, CVE-2024-26720, CVE-2024-26736,
CVE-2024-26898, CVE-2021-47063, CVE-2023-52615)
