Summary

Xuewei Feng, Chuanpu Fu, Qi Li, Kun Sun, and Ke Xu discovered that the TCP
implementation in the Linux kernel did not properly handle IPID assignment.
A remote attacker could use this to cause a denial of service (connection
termination) or inject forged data. (CVE-2020-36516)

Ke Sun, Alyssa Milburn, Henrique Kawakami, Emma Benoit, Igor Chervatyuk,
Lisa Aichele, and Thais Moreira Hamasaki discovered that the Spectre
Variant 2 mitigations for AMD processors on Linux were insufficient in some
situations. A local attacker could possibly use this to expose sensitive
information. (CVE-2021-26401)

Jürgen Groß discovered that the Xen subsystem within the Linux kernel did
not adequately limit the number of events driver domains (unprivileged PV
backends) could send to other guest VMs. An attacker in a driver domain
could use this to cause a denial of service in other guest VMs.
(CVE-2021-28712, CVE-2021-28713)

Wolfgang Frisch discovered that the ext4 file system implementation in the
Linux kernel contained an integer overflow when handling metadata inode
extents. An attacker could use this to construct a malicious ext4 file
system image that, when mounted, could cause a denial of service (system
crash). (CVE-2021-3428)

It was discovered that the IEEE 802.15.4 wireless network subsystem in the
Linux kernel did not properly handle certain error conditions, leading to a
null pointer dereference vulnerability. A local attacker could possibly use
this to cause a denial of service (system crash). (CVE-2021-3659)

It was discovered that the System V IPC implementation in the Linux kernel
did not properly handle large shared memory counts. A local attacker could
use this to cause a denial of service (memory exhaustion). (CVE-2021-3669)

Alois Wohlschlager discovered that the overlay file system in the Linux
kernel did not restrict private clones in some situations. An attacker
could use this to expose sensitive information. (CVE-2021-3732)

It was discovered that the SCTP protocol implementation in the Linux kernel
did not properly verify VTAGs in some situations. A remote attacker could
possibly use this to cause a denial of service (connection disassociation).
(CVE-2021-3772)

It was discovered that the btrfs file system implementation in the Linux
kernel did not properly handle locking in certain error conditions. A local
attacker could use this to cause a denial of service (kernel deadlock).
(CVE-2021-4149)

Jann Horn discovered that the socket subsystem in the Linux kernel
contained a race condition when handling listen() and connect() operations,
leading to a read-after-free vulnerability. A local attacker could use this
to cause a denial of service (system crash) or possibly expose sensitive
information. (CVE-2021-4203)

It was discovered that the file system quotas implementation in the Linux
kernel did not properly validate the quota block number. An attacker could
use this to construct a malicious file system image that, when mounted and
operated on, could cause a denial of service (system crash).
(CVE-2021-45868)

Zhihua Yao discovered that the MOXART SD/MMC driver in the Linux kernel did
not properly handle device removal, leading to a use-after-free
vulnerability. A physically proximate attacker could possibly use this to
cause a denial of service (system crash). (CVE-2022-0487)

It was discovered that the block layer subsystem in the Linux kernel did
not properly initialize memory in some situations. A privileged local
attacker could use this to expose sensitive information (kernel memory).
(CVE-2022-0494)

It was discovered that the UDF file system implementation in the Linux
kernel could attempt to dereference a null pointer in some situations. An
attacker could use this to construct a malicious UDF image that, when
mounted and operated on, could cause a denial of service (system crash).
(CVE-2022-0617)

David Bouman discovered that the netfilter subsystem in the Linux kernel
did not initialize memory in some situations. A local attacker could use
this to expose sensitive information (kernel memory). (CVE-2022-1016)

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 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)

It was discovered that the tty subsystem in the Linux kernel contained a
race condition in certain situations, leading to an out-of-bounds read
vulnerability. A local attacker could possibly use this to cause a denial
of service (system crash) or expose sensitive information. (CVE-2022-1462)

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)

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)

It was discovered that the HID subsystem in the Linux kernel did not
properly validate inputs in certain conditions. A local attacker with
physical access could plug in a specially crafted USB device to expose
sensitive information. (CVE-2022-20132)

It was discovered that th
