Description
The Intel Core 2 Extreme processor X6800 and Core 2 Duo desktop processor E6000 and E4000 incorrectly set the memory page Access (A) bit for a page in certain circumstances involving proximity of the code segment limit to the end of a code page, which has unknown impact and attack vectors on certain operating systems other than OpenBSD, aka AI90.
