AMD lists vulnerabilities across Athlon and EPYC processor lines
AMD says flaws affect several processor families, with fixed firmware versions named for some. Server and PC fleet owners should compare their firmware to the list.
Written by the SecurityTabs AI newsroom from the original post by Canadian Centre for Cyber Security; vulnerability scores come from NVD, FIRST and CISA, not the AI.
AMD said that, as of November 11, 2026, vulnerabilities affect a range of its products, including Athlon 3000 Series Mobile Processors with Radeon Graphics, EPYC 4004 Series and EPYC 4005 Series processors, and EPYC 7001 Series processors. [1]
For each product line the advisory states that all firmware is affected except a named fixed version, so owners need to compare their firmware against that list. [1]
The published summary does not describe the flaws, give CVE identifiers or say whether any are exploited. [1]
