Privileged local denial of service via out-of-bounds write
Published Jun 9, 2021 · Updated Aug 4, 2024
Out-of-bounds write in Intel(R) Processors firmware allows privileged local users to cause denial of service. The BIOS firmware performs an out-of-bounds write while processing firmware data, corrupting memory and interrupting service. Exploitation requires privileged local access; the documented consequence is denial of service without stated confidentiality or integrity impact.
