First published: Tue Aug 20 2024(Updated: )
It was discovered that some Intel® Core™ Ultra Processors did not properly isolate the stream cache. A local authenticated user could potentially use this to escalate their privileges. (CVE-2023-42667) It was discovered that some Intel® Processors did not properly isolate the stream cache. A local authenticated user could potentially use this to escalate their privileges. (CVE-2023-49141) It was discovered that some Intel® Processors did not correctly transition between the executive monitor and SMI transfer monitor (STM). A privileged local attacker could use this to escalate their privileges. (CVE-2024-24853) It was discovered that some 3rd, 4th, and 5th Generation Intel® Xeon® Processors failed to properly implement a protection mechanism. A local attacker could use this to potentially escalate their privileges. (CVE-2024-24980) It was discovered that some 3rd Generation Intel Xeon Scalable Processors did not properly handle mirrored regions with different values. A privileged local user could use this to cause a denial of service (system crash). (CVE-2024-25939)
