As we told you a couple of weeks ago, Linus Torvalds and the other developers of the open source community recently launched version 5.19 of the Linux kernel, which in this case implements mitigations to combat the new dangerous vulnerability RetBleed, which, as well as Meltdown and Specter in the past, uses branch target injection to intercept information on modern processors, such as those of the AMD Zen ranges (up to Zen 2), as well as Intel Skylake, Kaby Lake and Coffee Lake. Other important patches concern the btrfs filesystem and the firmware for Intel GPU controllers which sometimes inadvertently disabled the graphics boosters on some new
Intel Alder Lake processors.

Apple In the notes of kernel publication we can find quite interesting information, namely that Linux Torvalds used an Apple
MacBook Air M2 notebook, a choice that aroused some curiosity. Torvalds himself wrote:
It's something I've been waiting for a long time [sic] and finally it's a reality, thanks to the Asahi team. We have had arm64 hardware with Linux for a long time, but none of it has been truly usable as a development platform until now.| ); }
