Several third-party GUIs are being developed for configuration, desktop implementations, and editors […]

Release of Memtest86+ 6.00 with UEFI support.

Posted on

After 9 years since the last significant branch was formed, the release of the memory testing program MemTest86+ 6.00 has been published. The program is not tied to any operating systems and can be run directly from the BIOS/UEFI firmware or from a bootloader for a full memory check. In case of detected issues, the built-in MemTest86+ memory failure map can be used in the kernel […]

Linus Torvalds suggested stopping support for i486 CPUs in the Linux kernel.

Posted on

During the discussion on workarounds for x86 processors that do not support the 'cmpxchg8b' instruction, Linus Torvalds stated that it may be time to mandate the presence of this instruction for kernel operation and to drop support for i486 processors that do not support 'cmpxchg8b', instead of trying to emulate this instruction on processors that are no longer used. Currently […]

Vulnerability in the library implementing the SHA-3 algorithm

Posted on

A vulnerability (CVE-2022-37454) has been identified in the implementation of the SHA-3 (Keccak) cryptographic hash function, proposed in the XKCP (eXtended Keccak Code Package), which could lead to a buffer overflow when processing specifically formatted data. The issue arises from an error in the specific implementation of SHA-3, rather than a flaw in the algorithm itself. The XKCP package is presented as the official implementation of SHA-3, developed with the participation of the developer team […]
