It was discovered that the Linux kernel did not properly restrict access to
the kernel debugger when booted in secure boot environments. A privileged
attacker could use this to bypass UEFI Secure Boot restrictions.
(CVE-2022-21499)
Aaron Adams discovered that the netfilter subsystem in the Linux kernel did
not properly handle the removal of stateful expressions 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 execute arbitrary code.
(CVE-2022-1966)
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-2022-1836)
Ziming Zhang discovered that the netfilter subsystem in the Linux kernel
did not properly validate sets with multiple ranged fields. A local
attacker could use this to cause a denial of service or execute arbitrary
code. (CVE-2022-1972)
