USN-6818-3: Linux kernel (NVIDIA) vulnerabilities
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) It was discovered that the Intel Data Streaming and Intel Analytics Accelerator drivers in the Linux kernel allowed direct access to the devices for unprivileged users and virtual machines. A local attacker could use this to cause a denial of service. (CVE-2024-21823) 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. This update corrects flaws in the following subsystems:
