USN-6311-1: Linux kernel vulnerabilities

First published: Mon Aug 28 2023(Updated: )

William Zhao discovered that the Traffic Control (TC) subsystem in the Linux kernel did not properly handle network packet retransmission in certain situations. A local attacker could use this to cause a denial of service (kernel deadlock). (CVE-2022-4269) It was discovered that the NTFS file system implementation in the Linux kernel did not properly check buffer indexes in certain situations, leading to an out-of-bounds read vulnerability. A local attacker could possibly use this to expose sensitive information (kernel memory). (CVE-2022-48502) Seth Jenkins discovered that the Linux kernel did not properly perform address randomization for a per-cpu memory management structure. A local attacker could use this to expose sensitive information (kernel memory) or in conjunction with another kernel vulnerability. (CVE-2023-0597) It was discovered that a race condition existed in the btrfs file system implementation in 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 expose sensitive information. (CVE-2023-1611) It was discovered that the APM X-Gene SoC hardware monitoring driver in the Linux kernel contained a race condition, 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-2023-3141) Quentin Minster discovered that the KSMBD implementation in the Linux kernel did not properly validate pointers in some situations, leading to a null pointer dereference vulnerability. A remote attacker could use this to cause a denial of service (system crash). (CVE-2023-32248) It was discovered that the kernel->user space relay implementation in the Linux kernel did not properly perform certain buffer calculations, leading to an out-of-bounds read vulnerability. A local attacker could use this to cause a denial of service (system crash) or expose sensitive information (kernel memory). (CVE-2023-3268) It was discovered that the Qualcomm EMAC ethernet driver in the Linux kernel did not properly handle device removal, leading to a user-after free vulnerability. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-33203) It was discovered that the BQ24190 charger driver in the Linux kernel did not properly handle device removal, leading to a user-after free vulnerability. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-33288) It was discovered that the video4linux driver for Philips based TV cards 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-2023-35823) It was discovered that the SDMC DM1105 PCI device 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-2023-35824) It was discovered that the Renesas USB controller driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A privileged attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-35828) It was discovered that the Rockchip Video Decoder IP driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability.
