USN-6919-1: Linux kernel vulnerabilities

Ziming Zhang discovered that the DRM driver for VMware Virtual GPU in the Linux kernel did not properly handle certain error conditions, leading to a NULL pointer dereference. A local attacker could exploit this vulnerability, identified as CVE-2022-38096, to cause a denial of service.

Additionally, a race condition was found in the ATA over Ethernet (AoE) driver, leading to a use-after-free vulnerability, denoted as CVE-2023-6270. This flaw allows attackers to potentially execute arbitrary code or cause a denial of service.

The situation escalates with another NULL pointer dereference in the Atheros 802.11ac wireless driver (CVE-2023-7042), and a similar issue within the HugeTLB file system component of the Linux Kernel (CVE-2024-0841). Affecting mainly privileged attackers, these vulnerabilities could be exploited to cause further denials of service.

Intel's Data Streaming and Intel Analytics Accelerator drivers (CVE-2024-21823) also presented a significant security risk by allowing direct device access for unprivileged users and virtual machines, potentially leading to system disruptions.

Moreover, Gui-Dong Han pointed out that a race condition in the software RAID driver could lead to an integer overflow (CVE-2024-23307), heightening the risk for a significant system crash or denial of service.
