Summary
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)
Billy Jheng Bing Jhong discovered that the CIFS network file system
implementation in the Linux kernel did not properly validate arguments to
ioctl() in some situations. A local attacker could possibly use this to
cause a denial of service (system crash). (CVE-2022-0168)
Hu Jiahui discovered that multiple race conditions existed in the Advanced
Linux Sound Architecture (ALSA) framework, leading to use-after-free
vulnerabilities. A local attacker could use these to cause a denial of
service (system crash) or possibly execute arbitrary code. (CVE-2022-1048)
Qiuhao Li, Gaoning Pan and Yongkang Jia discovered that the KVM
implementation in the Linux kernel did not properly perform guest page
table updates in some situations. An attacker in a guest vm could possibly
use this to crash the host OS. (CVE-2022-1158)
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 6pack protocol implementation in the Linux
kernel did not handle detach events properly in some situations, leading to
a use-after-free vulnerability. A local attacker could use this to cause a
denial of service (system crash). (CVE-2022-1198)
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)
Qiuhao Li, Gaoning Pan, and Yongkang Jia discovered that the kvm
implementation in the Linux kernel did not handle releasing a virtual cpu
properly. A local attacker in a guest VM coud possibly use this to cause a
denial of service (host system crash). (CVE-2022-1263)
It was discovered that the PF_KEYv2 implementation in the Linux kernel did
not properly initialize kernel memory in some situations. A local attacker
could use this to expose sensitive information (kernel memory).
(CVE-2022-1353)
It was discovered that the implementation of X.25 network protocols in the
Linux kernel did not terminate link layer sessions properly. A local
attacker could possibly use this to cause a denial of service (system
crash). (CVE-2022-1516)
It was discovered that the ACRN Hypervisor Service Module implementation in
the Linux kernel did not properly deallocate memory in some situations. A
local privileged attacker could possibly use this to cause a denial of
service (memory exhaustion). (CVE-2022-1651)
It was discovered that the RxRPC session socket implementation in the Linux
kernel did not properly handle ioctls called when no security protocol is
given. A local attacker could use this to cause a denial of service (system
crash) or possibly expose sensitive information (kernel memory).
(CVE-2022-1671)
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)
赵子轩 discovered that the 802.2 LLC type 2 driver in the Linux kernel did not
properly perform reference counting in some error conditions. A local
attacker could use this to cause a denial of service. (CVE-2022-28356)
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)
It was discovered that the Microchip CAN BUS Analyzer 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-2022-28389)
It was discovered that the EMS CAN/USB interface implementation in the
Linux kernel contained a double-free vulnerability when handling certain
error conditions. A local attacker could use this to cause a denial of
service (memory exhaustion). (CVE-2022-28390)
