After being alerted by Google safety researchers, Intel has simply introduced the Reptar safety flaw affecting a number of of the corporate’s processors. The listing contains the newest Alder Lake, Raptor Lake and Sapphire Rapids architectures. This flaw has the potential to “allow elevation of privileges and/or disclosure of data and/or denial of service by way of native entry […] In addition, the vulnerability may doubtlessly result in disclosure of data or elevation of privileges”. The full listing of processors affected by this flaw, referenced by Intel as CVE-2023-23583, is offered right here.
Microcode has already been launched, however one of the best ways to mitigate this vulnerability is at {hardware} degree. It’s fascinating to notice that the 14th technology will not be affected by this flaw, which implies that various processors have already been corrected in {hardware}.
Other processors can due to this fact profit from a software program patch, within the type of microcode and globally. Now, let’s be goal: only a few customers run any danger in utilizing their machine on account of this breach. However, it’s indeniable that the buildup of those software program patches finally results in a lack of efficiency for the general system. For the second, this has not been measured, however extra info is anticipated on this exact topic.
