It has been reported that due to this bug, a user can cause denial of service (DoS) and arbitrary code execution. In order to protect your Linux system against this issue, update the kernel package or install another one on top of it.
It has been reported that due to this bug, a user can cause denial of service (DoS) and arbitrary code execution. In order to protect your Linux system against this issue, update the kernel package or install another one on top of it. The second critical vulnerability discovered in the Linux Kernel was found by HvH. It has been declared as High severity. This vulnerability affects the function execve of the file /lib/tls/x509/x509_vfy.c of the component X.509. The manipulation leads to NULL pointer dereference. It is recommended to apply a patch to fix this issue. VDB-211931 is the identifier assigned to this vulnerability.

Check the kernel version
If you are unsure which kernel to apply the patch for, you can check your kernel version. Install the latest kernel release that is not vulnerable to the vulnerability by installing a new kernel.
The third critical vulnerability discovered in the Linux Kernel was found by HvH
The third critical vulnerability discovered in the Linux Kernel was found by HvH. It has been declared as High severity. This vulnerability affects the function of the component crypto/chacha20poly1305_generic. The manipulation leads to buffer overflow and an information leak. It is recommended to apply a patch to fix this issue. VDB-219468 is the identifier assigned to this vulnerability.

It is recommended to apply a patch to fix this issue. VDB-219468 is the identifier assigned to this vulnerability. The fourth critical vulnerability discovered in the Linux Kernel was found by HvH and it has been declared as High severity. This vulnerability concerns with file /lib/modules/4.15-1-MANJARO-X86_64/build/include/linux/timex.h of the component timex, causing denial of service (DoS) via NULL pointer dereference on 32bit ARM systems only at least when running on a kernel compiled for 64 bit AArch64 architecture or no timex support at all (tux on recent kernels). In order not to take risks, update your kernel package or install another one on top of it so that you are protected
What is Linux?
Linux is a Unix-like computer operating system kernel, originally implemented by Linus Torvalds and now maintained as an international project. It's the most widely used open source OS on the planet with almost two-thirds of the server market share in terms of shipments.
Linux is a Unix-like computer operating system kernel, originally implemented by Linus Torvalds and now maintained as an international project. It's the most widely used open source OS on the planet with almost two-thirds of the server market share in terms of shipments. Linux is free for anyone to use, modify, or distribute at will. The only requirement for Linux is that you must pass its test suite: The Linux Test Project
Vulnerability Causation and Impact
The vulnerability was caused due to improper validation of input for the function execve. This leads to overflow/underflow in pointer which causes NULL pointer. The vulnerability could lead to DoS and arbitrary code execution. The vulnerability has been assigned CVE-2022-3629 identifier. It is recommended to apply a patch to fix this issue.
