USN-6938-1: Linux kernel vulnerabilities

First published: Wed Jul 31 2024(Updated: )

It was discovered that the device input subsystem in the Linux kernel did not properly handle the case when an event code falls outside of a bitmap. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-48619) 黄思聪 discovered that the NFC Controller Interface (NCI) implementation in the Linux kernel did not properly handle certain memory allocation failure conditions, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-46343) It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel when modifying certain settings values through debugfs. A privileged local attacker could use this to cause a denial of service. (CVE-2024-24857, CVE-2024-24858, CVE-2024-24859) Chenyuan Yang discovered that the Unsorted Block Images (UBI) flash device volume management subsystem did not properly validate logical eraseblock sizes in certain situations. An attacker could possibly use this to cause a denial of service (system crash). (CVE-2024-25739) 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:
