Description

linux, linux-aws, linux-aws-5.4, linux-gcp, linux-gcp-5.4, linux-gkeop, 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 Jann Horn discovered that the Linux kernel did not properly track memory allocations for anonymous VMA mappings in some situations, leading to potential data structure reuse. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-42703) It was discovered that a memory leak existed in the IPv6 implementation of the Linux kernel. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2022-3524) It was discovered that a race condition existed in the Bluetooth 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-2022-3564) It was discovered that the ISDN implementation of the Linux kernel contained a use-after-free vulnerability. A privileged user could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-3565) It was discovered that the TCP implementation in the Linux kernel contained a data race condition. An attacker could possibly use this to cause undesired behaviors. (CVE-2022-3566) It was discovered that the IPv6 implementation in the Linux kernel contained a data race condition. An attacker could possibly use this to cause undesired behaviors. (CVE-2022-3567) It was discovered that the Realtek RTL8152 USB Ethernet adapter driver in the Linux kernel did not properly handle certain error conditions. A local attacker with physical access could plug in a specially crafted USB device to cause a denial of service (memory exhaustion). (CVE-2022-3594) It was discovered that a null pointer dereference existed in the NILFS2 file system implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-3621)
