Description

linux, linux-aws, linux-aws-5.4, linux-azure, linux-azure-5.4, linux-azure-fde, linux-gcp, linux-gcp-5.4, linux-gke, linux-gke-5.4, linux-gkeop, linux-gkeop-5.4, linux-hwe-5.4, linux-ibm, linux-ibm-5.4, linux-kvm, linux-oracle, linux-oracle-5.4, linux-raspi, linux-raspi-5.4 vulnerabilities It was discovered that the Linux kernel did not properly restrict access to the kernel debugger when booted in secure boot environments. A privileged attacker could use this to bypass UEFI Secure Boot restrictions. (CVE-2022-21499) Aaron Adams discovered that the netfilter subsystem in the Linux kernel did not properly handle the removal of stateful expressions in some situations, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-1966) It was discovered that the SCTP protocol implementation in the Linux kernel did not properly verify VTAGs in some situations. A remote attacker could possibly use this to cause a denial of service (connection disassociation). (CVE-2021-3772) Eric Biederman discovered that the cgroup process migration implementation in the Linux kernel did not perform permission checks correctly in some situations. A local attacker could possibly use this to gain administrative privileges. (CVE-2021-4197) Jann Horn discovered that the FUSE file system 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-2022-1011) Qiuhao Li, Gaoning Pan and Yongkang Jia discovered that the KVM implementation in the Linux kernel did not properly perform guest page table updates in some situations. An attacker in a guest vm could possibly use this to crash the host OS. (CVE-2022-1158) Duoming Zhou discovered that the 6pack protocol implementation in the Linux kernel did not handle detach events properly in some situations, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-1198) It was discovered that the PF_KEYv2 implementation in the Linux kernel did not properly initialize kernel memory in some situations. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2022-1353) It was discovered that the implementation of X.25 network protocols in the Linux kernel did not terminate link layer sessions properly. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-1516) Demi Marie Obenour and Simon Gaiser discovered that several Xen para- virtualization device frontends did not properly restrict the access rights of device backends. An attacker could possibly use a malicious Xen backend to gain access to memory pages of a guest VM or cause a denial of service in the guest. (CVE-2022-23036, CVE-2022-23037, CVE-2022-23038, CVE-2022-23039, CVE-2022-23040, CVE-2022-23041, CVE-2022-23042) It was discovered that the USB Gadget file system interface 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-2022-24958) It was discovered that the USB SR9700 ethernet device driver for the Linux kernel did not properly validate the length of requests from the device. A physically proximate attacker could possibly use this to expose sensitive information (kernel memory). (CVE-2022-26966) 赵子轩 discovered that the 802.2 LLC type 2 driver in the Linux kernel did not properly perform reference counting in some error conditions. A local attacker could use this to cause a denial of service. (CVE-2022-28356) It was discovered that the Microchip CAN BUS Analyzer interface implementation in the Linux kernel did not properly handle certain error conditions, leading to a double-free. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-28389) It was discovered that the EMS CAN/USB interface implementation in the Linux kernel contained a double-free vulnerability when handling certain error conditions. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2022-28390)
