USN-6725-1: Linux kernel vulnerabilities

Published Apr 9, 2024
·
Updated

Chih-Yen Chang discovered that the KSMBD implementation in the Linux kernel did not properly validate certain data structure fields when parsing lease contexts, 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-2023-1194)

Quentin Minster discovered that a race condition existed in the KSMBD implementation in the Linux kernel, leading to a use-after-free vulnerability. A remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-32254)

It was discovered that a race condition existed in the KSMBD implementation in the Linux kernel when handling session connections, leading to a use- after-free vulnerability. A remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-32258)

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 SMB request protocol IDs, leading to a out-of- bounds read vulnerability. A remote attacker could possibly use this to cause a denial of service (system crash). (CVE-2023-38430)

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)

It was discovered that the KSMBD implementation in the Linux kernel did not properly handle session setup requests, leading to an out-of-bounds read vulnerability. A remote attacker could use this to expose sensitive information. (CVE-2023-3867)

Pratyush Yadav discovered that the Xen network backend implementation in the Linux kernel did not properly handle zero length data request, leading to a null pointer dereference vulnerability. An attacker in a guest VM could possibly use this to cause a denial of service (host domain crash). (CVE-2023-46838)

It was discovered that the IPv6 implementation of the Linux kernel did not properly manage route cache memory usage. A remote attacker could use this to cause a denial of service (memory exhaustion). (CVE-2023-52340)

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)

Yang Chaoming discovered that the KSMBD implementation in the Linux kernel did not properly validate request buffer sizes, leading to an out-of-bounds read vulnerability. An attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2024-22705)

Chenyuan Yang discovered that the btrfs file system in the Linux kernel did not properly handle read operations on newly created subvolumes in certain conditions. A local attacker could use this to cause a denial of service (system crash). (CVE-2024-23850)

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: - Architecture specifics; - Block layer; - Cryptographic API; - Android drivers; - EDAC drivers; - GPU drivers; - Media drivers; - Multifunction device drivers; - MTD block device drivers; - Network drivers; - NVME drivers; - TTY drivers; - Userspace I/O drivers; - EFI Variable file system; - F2FS file system; - GFS2 file system; - SMB network file system; - BPF subsystem; - IPv6 Networking; - Network Traffic Control; - AppArmor security module; (CVE-2023-52463, CVE-2023-52445, CVE-2023-52462, CVE-2023-52609, CVE-2023-52448, CVE-2023-52457, CVE-2023-52464, CVE-2023-52456, CVE-2023-52454, CVE-2023-52438, CVE-2023-52480, CVE-2023-52443, CVE-2023-52442, CVE-2024-26631, CVE-2023-52439, CVE-2023-52612, CVE-2024-26598, CVE-2024-26586, CVE-2024-26589, CVE-2023-52444, CVE-2023-52436, CVE-2024-26633, CVE-2024-26597, CVE-2023-52458, CVE-2024-26591, CVE-2023-52449, CVE-2023-52467, CVE-2023-52441, CVE-2023-52610, CVE-2023-52451, CVE-2023-52469, CVE-2023-52470)
