Short of details: https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00438.html
Per Intel, this was fixed by a firmware update. v49.0.1 of the
firmware is required. The new firmware requires a kernel patch
https://git.kernel.org/linus/c784e5249e773689e38d2bc1749f08b986621a26
Firmware was added via https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=c487f7dadcd21116613441ed355b764003b3f57b
The vulnerability is fixed in firmware, but needs an updated Linux kernel to load
the updated firmware, thus also marking linux as affected
