Affected: Kernel

A flaw use after free in the Linux kernel video4linux driver was found in the way user triggers em28xx_usb_probe() for the Empia 28xx based TV cards. A local user could use this flaw to crash the system or potentially escalate their privileges on the system.

Affected: Ubuntu:18.04:LTS: linux, Ubuntu:18.04:LTS: linux-aws, Ubuntu:18.04:LTS: linux-dell300x, Ubuntu:18.04:LTS: linux-gcp-4.15, Ubuntu:18.04:LTS: linux-kvm, Ubuntu:18.04:LTS: linux-oracle, Ubuntu:18.04:LTS: linux-raspi2, Ubuntu:18.04:LTS: linux-snapdragon

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 the video4linux driver for Empia based TV cards in the Linux kernel did not properly perform reference counting 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 possibly execute arbitrary code. (CVE-2022-3239)

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. (CV…
