CVE-2025-26403 [HIGH] Intel Microcode vulnerabilities
Title: Intel Microcode vulnerabilities
Summary: Several security issues were fixed in Intel Microcode.
Barak Gross discovered that some Intel® Xeon® processors with SGX enabled
did not properly handle buffer restrictions. A local authenticated user
could potentially use this issue to escalate their privileges.
(CVE-2025-20053)
Avinash Maddy discovered that some Intel® processors did not properly
isolate or compartmentalize the stream cache mechanisms. A local
authenticated user could potentially use this issue to escalate their
privileges. (CVE-2025-20109)
Joseph Nuzman discovered that some Intel® Xeon® processors did not properly
manage references to active allocate resources. A local authenticated user
could potentially use this issue to cause a denial of service (system
crash). (CVE
