Details

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)

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)

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