It exists that a race condition existed in the instruction emulator of the Linux kernel on Arm 64-bit systems. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-20422) ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.

Older AMD, Intel chips vulnerable to data-leaking 'Retbleed' Spectre variant

The Register • Thomas Claburn in San Francisco • 12 Jul 2022

Topics Security Off-Prem On-Prem Software Offbeat Vendor Voice Vendor Voice Resources Speculative execution side-channels continue to haunt silicon world

Older AMD and Intel chips are vulnerable to yet another Spectre-based speculative-execution attack that exposes secrets within kernel memory despite defenses already in place. Mitigating this side channel is expected to take a toll on performance. ETH Zurich computer scientists Johannes Wikner and Kaveh Razavi have dubbed the attack Retbleed, which they describe as an addition to the family of speculative-execution flaws known as Spectre-BTI (variant 2) that can be exploited by branch target inj...
