Details
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). (

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)
