Intel and AMD have issued ten new security advisories on Patch Tuesday to inform customers about vulnerabilities in their products.

Intel released eight new advisories, two of which describe high-severity vulnerabilities. One of the most serious issues is a local privilege escalation that affects the BIOS firmware for some Intel processors. The second is a local privilege escalation that affects the on-chip debug and test interface in some 4th Generation Intel Xeon processors running SGX or TDX technology.
