USN-6765-1: Linux kernel (OEM) vulnerabilities

Read Time:3 Minute, 33 Second

Alon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel
did not properly validate H2C PDU data, leading to a null pointer
dereference vulnerability. A remote attacker could use this to cause a
denial of service (system crash). (CVE-2023-6356, CVE-2023-6535,
CVE-2023-6536)

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)

Chenyuan Yang discovered that the RDS Protocol implementation in the Linux
kernel contained an out-of-bounds read vulnerability. An attacker could use
this to possibly cause a denial of service (system crash). (CVE-2024-23849)

It was discovered that a race condition existed in the Bluetooth subsystem
in the Linux kernel, leading to a null pointer dereference vulnerability. A
privileged local attacker could use this to possibly cause a denial of
service (system crash). (CVE-2024-24860)

Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
