Description

linux, linux-aws, linux-aws-hwe, linux-azure, linux-azure-4.15, linux-dell300x, linux-gcp, linux-gcp-4.15, linux-hwe, linux-kvm, linux-oracle, linux-raspi2, linux-snapdragon vulnerabilities It was discovered that the BPF verifier in the Linux kernel did not properly handle internal data structures. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2021-4159) 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) 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) 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) 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) 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)
