CVE-2022-0382
https://notcve.org/view.php?id=CVE-2022-0382
11 Feb 2022 — An information leak flaw was found due to uninitialized memory in the Linux kernel's TIPC protocol subsystem, in the way a user sends a TIPC datagram to one or more destinations. This flaw allows a local user to read some kernel memory. This issue is limited to no more than 7 bytes, and the user cannot control what is read. This flaw affects the Linux kernel versions prior to 5.17-rc1.

CVE-2022-24448 – kernel: nfs_atomic_open() returns uninitialized data instead of ENOTDIR
https://notcve.org/view.php?id=CVE-2022-24448
04 Feb 2022 — An issue was discovered in fs/nfs/dir.c in the Linux kernel before 5.16.5. If an application sets the O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup. If a regular file is found, ENOTDIR should occur, but the server instead returns uninitialized data in the file descriptor.

CVE-2022-0264
https://notcve.org/view.php?id=CVE-2022-0264
04 Feb 2022 — A vulnerability was found in the Linux kernel's eBPF verifier when handling internal data structures. Internal memory locations could be returned to userspace. A local attacker with the permissions to insert eBPF code to the kernel can use this to leak internal kernel memory details defeating some of the exploit mitigations in place for the kernel.

CVE-2021-20322 – kernel: new DNS Cache Poisoning Attack based on ICMP fragment needed packets replies
https://notcve.org/view.php?id=CVE-2021-20322
03 Feb 2022 — A flaw in the processing of received ICMP errors (ICMP fragment needed and ICMP redirect) in the Linux kernel functionality was found to allow the ability to quickly scan open UDP ports. This flaw allows an off-path remote user to effectively bypass the source port UDP randomization. The highest threat from this vulnerability is to confidentiality and possibly integrity, because software that relies on UDP source port randomization are indirectly affected as well.

CVE-2021-3752 – kernel: possible use-after-free in bluetooth module
https://notcve.org/view.php?id=CVE-2021-3752
03 Feb 2022 — A use-after-free flaw was found in the Linux kernel’s Bluetooth subsystem in the way user calls connect to the socket and disconnect simultaneously due to a race condition. This flaw allows a user to crash the system or escalate their privileges. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
