USN-5792-2: Linux kernel vulnerabilities

First published: Mon Jan 09 2023(Updated: )

Mingwei Zhang discovered that the KVM implementation for AMD processors in the Linux kernel did not properly handle cache coherency with Secure Encrypted Virtualization (SEV). A local attacker could possibly use this to cause a denial of service (host system crash). (CVE-2022-0171) It was discovered that a race condition existed in the Android Binder IPC subsystem 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 execute arbitrary code. (CVE-2022-20421) David Leadbeater discovered that the netfilter IRC protocol tracking implementation in the Linux Kernel incorrectly handled certain message payloads in some situations. A remote attacker could possibly use this to cause a denial of service or bypass firewall filtering. (CVE-2022-2663) It was discovered that the Intel 740 frame buffer driver in the Linux kernel contained a divide by zero vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-3061) It was discovered that the sound subsystem in the Linux kernel contained a race condition in some situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-3303) Gwnaun Jung discovered that the SFB packet scheduling 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-2022-3586) It was discovered that the NILFS2 file system implementation in the Linux kernel did not properly deallocate memory in certain error conditions. An attacker could use this to cause a denial of service (memory exhaustion). (CVE-2022-3646) Khalid Masum discovered that the NILFS2 file system implementation in the Linux kernel did not properly handle certain error conditions, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2022-3649) Jann Horn discovered a race condition existed in the Linux kernel when unmapping VMAs in certain situations, resulting in possible use-after-free vulnerabilities. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-39188) Hyunwoo Kim discovered that an integer overflow vulnerability existed in the PXA3xx graphics driver in the Linux kernel. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-39842) It was discovered that a race condition existed in the EFI capsule loader driver 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 execute arbitrary code. (CVE-2022-40307) Zheng Wang and Zhuorao Yang discovered that the RealTek RTL8712U wireless driver 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-2022-4095) It was discovered that the USB monitoring (usbmon) component in the Linux kernel did not properly set permissions on memory mapped in to user space processes. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-43750)
