USN-6740-1: Linux kernel vulnerabilities

First published: Fri Apr 19 2024(Updated: )

Wei Chen discovered that a race condition existed in the TIPC protocol implementation in the Linux kernel, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-1382) It was discovered that the virtio network implementation in the Linux kernel did not properly handle file references in the host, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information (kernel memory). (CVE-2023-1838) Jose Oliveira and Rodrigo Branco discovered that the Spectre Variant 2 mitigations with prctl syscall were insufficient in some situations. A local attacker could possibly use this to expose sensitive information. (CVE-2023-1998) Daniele Antonioli discovered that the Secure Simple Pairing and Secure Connections pairing in the Bluetooth protocol could allow an unauthenticated user to complete authentication without pairing credentials. A physically proximate attacker placed between two Bluetooth devices could use this to subsequently impersonate one of the paired devices. (CVE-2023-24023) shanzhulig discovered that the DRM subsystem in the Linux kernel contained a race condition when performing certain operation while handling driver unload, leading to 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-2023-51043) It was discovered that a race condition existed in the Bluetooth subsystem of the Linux kernel, leading to 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-2023-51779) It was discovered that the device mapper driver in the Linux kernel did not properly validate target size during certain memory allocations. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-52429, CVE-2024-23851) Zhenghan Wang discovered that the generic ID allocator implementation in the Linux kernel did not properly check for null bitmap when releasing IDs. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-6915) It was discovered that the SCTP protocol implementation in the Linux kernel contained a race condition when handling lock acquisition in certain situations. A local attacker could possibly use this to cause a denial of service (kernel deadlock). (CVE-2024-0639) 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:
