It was discovered that the eBPF implementation in the Linux kernel did not
properly prevent writes to kernel objects in BPF_BTF_LOAD commands. A
privileged local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2022-0500)
It was discovered that the Marvell NFC device driver implementation in the
Linux kernel did not properly perform memory cleanup operations in some
situations, leading to a use-after-free vulnerability. A local attacker
could possibly use this to cause a denial of service (system) or execute
arbitrary code. (CVE-2022-1734)
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 in the host OS (system crash). (CVE-2022-1789)
Duoming Zhou discovered a race condition in the NFC subsystem in the Linux
kernel, leading to a use-after-free vulnerability. A privileged local
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2022-1974)
Duoming Zhou discovered that the NFC subsystem in the Linux kernel did not
properly prevent context switches from occurring during certain atomic
context operations. A privileged local attacker could use this to cause a
denial of service (system crash). (CVE-2022-1975)
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)
