USN-5539-1: Linux kernel vulnerabilities

First published: Thu Jul 28 2022(Updated: )

It was discovered that the implementation of the 6pack and mkiss protocols in the Linux kernel did not handle detach events properly in some situations, leading to a use-after-free vulnerability. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-1195) 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) Duoming Zhou discovered race conditions in the AX.25 amateur radio protocol implementation in the Linux kernel during device detach operations. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-1204) Duoming Zhou discovered race conditions in the AX.25 amateur radio protocol implementation in the Linux kernel, leading to use-after-free vulnerabilities. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-1205) Yongkang Jia discovered that the KVM hypervisor implementation in the Linux kernel did not properly handle guest TLB mapping invalidation requests in some situations. An attacker in a guest VM could use this to cause a denial of service (system crash) in the host OS. (CVE-2022-1789) It was discovered that the 8 Devices USB2CAN 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-2022-28388) Minh Yuan discovered that the floppy driver in the Linux kernel contained a race condition 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-2022-33981)
