USN-5729-2: Linux kernel vulnerabilities

First published: Fri Nov 18 2022(Updated: )

It was discovered that a race condition existed in the instruction emulator of the Linux kernel on Arm 64-bit systems. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-20422) Hsin-Wei Hung discovered that the BPF subsystem in the Linux kernel contained an out-of-bounds read vulnerability in the x86 JIT compiler. A local attacker could possibly use this to cause a denial of service (system crash) or expose sensitive information (kernel memory). (CVE-2022-2905) Hao Sun and Jiacheng Xu discovered that the NILFS file system implementation in the Linux kernel contained 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-2022-2978) Abhishek Shah discovered a race condition in the PF_KEYv2 implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information (kernel memory). (CVE-2022-3028) It was discovered that the Netlink device interface implementation in the Linux kernel did not properly handle certain error conditions, leading to a use-after-free vulnerability with some network device drivers. A local attacker with admin access to the network device could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-3625) It was discovered that the IDT 77252 ATM PCI device driver in the Linux kernel did not properly remove any pending timers during device exit, resulting in a use-after-free vulnerability. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-3635) Gwangun Jung discovered that the netfilter subsystem in the Linux kernel did not properly prevent binding to an already bound chain. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-39190) Xingyuan Mo and Gengjia Chen discovered that the Promise SuperTrak EX storage controller driver in the Linux kernel did not properly handle certain structures. A local attacker could potentially use this to expose sensitive information (kernel memory). (CVE-2022-40768)
