Researchers say this is CVE-2024-45332. INTEL-SA-01247 covers that CVE. Microcode release 20250512 has that INTEL-SA mitigated. https://github.com/intel/Intel-Linux-Processor-Microcode-Dat... https://www.intel.com/content/www/us/en/security…

Intel distributes microcode updates for Linux here: https://github.com/intel/Intel-Linux-Processor-Microcode-Dat... , and the distro are all set up to pull from there and distribute automatically. Not expert enough to know what to look for…

So where is the microcode update? I don't see anything for Linux yet. https://github.com/intel/Intel-Linux-Processor-Microcode-Dat...
comment by samlinnfer · 2024-07-26 · in There is no fix for Intel's crashing 13th/14th Gen CPUs – damage is permanent -
They have been partially reversed and ==maybe== definitely cracked, but it doesn't matter. The web or chain of trust of those updates from the vendor to the processor is what matters. They're at least CRC checked to prevent loading corrupt…

> How bad is this exactly? 7.1 out of 10 https://www.intel.com/content/www/us/en/security-center/advi... This was part of IPU 2021.2 in November and other bugs in other CPUs were fixed as well, one rated 8.2 affecting many, but not all,…
comment by Jon_Lowtek · 2022-02-07 · in Chip Red Pill: Arbitrary [Micro]Code Execution Inside Intel Atom CPUs -
Is it any more of a "magic incantation" than the linux-image-XYZ package which controls which OS kernel is installed? Or the linux-firmware package which controls what firmware gets loaded on various devices? If you want to see when Intel…

comment by michaellarabel · 2021-06-28 · in Intel to disable TSX by default on more CPUs with new microcode -
Thankfully I do save all of the microcodes, so I can just use an early version by simply rebuilding the initramfs. I also hold that package back on Arch, so it does not get upgraded. Might want to look for them here:…
comment by johnisgood · 2021-06-22 · in Your CPU may have slowed down on Wednesday -
It isn't clear if Haswell has this optimization. As an easy test you could run the zero-fill-bench linked in the post and check the fill0 vs fill1 numbers. If they are the same, Haswell probably never had this optimization in the first…

> When there's a bug in the CPU microcode, you're at the mercy of your motherboard vendor to release a new system BIOS that will update it for you—you can't just go to some download link at AMD and apply a fix yourself. At least on Linux,…
