Affected: kernel

A flaw was found in the Linux kernel’s driver for the ASIX AX88179_178A-based USB 2.0/3.0 Gigabit Ethernet Devices. The vulnerability contains multiple out-of-bounds reads and possible out-of-bounds writes.

Affected: Ubuntu:Pro:14.04:LTS: linux-aws, Ubuntu:Pro:14.04:LTS: linux-lts-xenial, Ubuntu:Pro:16.04:LTS: linux, Ubuntu:Pro:16.04:LTS: linux-aws, Ubuntu:Pro:16.04:LTS: linux-kvm

It was discovered that the framebuffer driver on the Linux kernel did not verify size limits when changing font or screen size, leading to an out-of- bounds write. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-33655)

It was discovered that the virtual terminal driver in the Linux kernel did not properly handle VGA console font changes, leading to an out-of-bounds write. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-33656)

Christian Brauner discovered that the XFS file system implementation in the Linux kernel did not properly handle setgid file creation. A local attacker could use this to gain elevated privileges. (CVE-2021-4037)

It was discovered that the ext4 file system implementation in the Linux kernel did not properly initialize memory in some situations. A privileged local attacker could use this to expose sensitive information (kernel memory). (CVE-2022-0850)

Duoming Zhou discovered that the AX.25 amateur radio protocol implementation in the Linux kernel did not handle detach events properly in some situations. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-1199)
