12 September 2024

Several security issues were fixed in the Linux kernel.

Releases
Ubuntu 24.04 LTS

Packages
linux-nvidia - Linux kernel for NVIDIA systems
linux-nvidia-lowlatency - Linux low latency kernel for NVIDIA systems

Details
Chenyuan Yang discovered that the CEC driver driver in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2024-23848)

It was discovered that the JFS file system contained an out-of-bounds read vulnerability when printing xattr debug information. A local attacker could use this to cause a denial of service (system crash). (CVE-2024-40902)

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