USN-6412-1: Linux kernel vulnerabilities

Published Oct 5, 2023
·
Updated

Hyunwoo Kim discovered that the DVB Core driver in the Linux kernel contained a race condition during device removal, leading to a use-after- free vulnerability. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-45886, CVE-2022-45919) Hyunwoo Kim discovered that the Technotrend/Hauppauge USB DEC driver in the Linux kernel did not properly handle device removal events. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2022-45887) It was discovered that the NTFS file system implementation in the Linux kernel did not properly validate MFT flags in certain situations. An attacker could use this to construct a malicious NTFS image that, when mounted and operated on, could cause a denial of service (system crash). (CVE-2022-48425) It was discovered that the IPv6 implementation in the Linux kernel contained a high rate of hash collisions in connection lookup table. A remote attacker could use this to cause a denial of service (excessive CPU consumption). (CVE-2023-1206) Daniel Trujillo, Johannes Wikner, and Kaveh Razavi discovered that some AMD processors utilising speculative execution and branch prediction may allow unauthorised memory reads via a speculative side-channel attack. A local attacker could use this to expose sensitive information, including kernel memory. (CVE-2023-20569) It was discovered that the IPv6 RPL protocol implementation in the Linux kernel did not properly handle user-supplied data. A remote attacker could use this to cause a denial of service (system crash). (CVE-2023-2156) Yang Lan discovered that the GFS2 file system implementation in the Linux kernel could attempt to dereference a null pointer in some situations. An attacker could use this to construct a malicious GFS2 image that, when mounted and operated on, could cause a denial of service (system crash). (CVE-2023-3212) It was discovered that the KSMBD implementation in the Linux kernel did not properly validate buffer sizes in certain operations, leading to an integer underflow and out-of-bounds read vulnerability. A remote attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2023-38427) Chih-Yen Chang discovered that the KSMBD implementation in the Linux kernel did not properly validate packet header sizes in certain situations, leading to an out-of-bounds read vulnerability. A remote attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2023-38431) Andy Nguyen discovered that the KVM implementation for AMD processors in the Linux kernel with Secure Encrypted Virtualization (SEV) contained a race condition when accessing the GHCB page. A local attacker in a SEV guest VM could possibly use this to cause a denial of service (host system crash). (CVE-2023-4155) It was discovered that the TUN/TAP driver in the Linux kernel did not properly initialize socket data. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-4194) Maxim Suhanov discovered that the exFAT file system implementation in the Linux kernel did not properly check a file name length, leading to an out- of-bounds write vulnerability. An attacker could use this to construct a malicious exFAT image that, when mounted and operated on, could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-4273)
