Do you make a point of regularly updating your computer's BIOS for security patches?
Asus has released a BIOS update to patch CVE-2026-93495, a vulnerability affecting motherboards designed for 8th and 9th generation Intel CPUs. This flaw could allow unauthorized memory access for users with direct physical control over the machine.
Why it matters
The patch addresses a security risk that could compromise system integrity if a malicious actor gains physical proximity to the hardware. It follows a separate high-severity software vulnerability report discovered in August 2026.
The vulnerability carries a CVSS severity score of 7.0. It stems from improper initialization in motherboard firmware, which can permit a user to read or write arbitrary memory when a specially crafted device is inserted into the PC.
The players
Asus
A multinational hardware company that produces computer motherboards, graphics cards, and laptops with a heavy focus on the gaming and enthusiast PC markets.
Intel
A global semiconductor manufacturer that develops the core CPU architectures used in the affected 8th and 9th generation systems.
The details
The vulnerability involves an initialization error within the BIOS, the fundamental software that manages the hardware components before the operating system boots. By inserting a specifically designed device into a port, a user with physical access can exploit this flaw to read or write arbitrary memory. This update is necessary to ensure that motherboard-level firmware correctly handles external device communication and prevents unauthorized memory manipulation.
Timeline
August 2026: A separate high-severity security vulnerability was discovered in Asus software.
October 1, 2026: Asus issued a security bulletin regarding the new BIOS update.
The Tech Race
This BIOS update follows the established security disclosure cycle for hardware vulnerabilities tracked by the CVE system. It marks a continued effort by motherboard manufacturers to secure aging architectures against modern physical attack vectors.
Users of ROG Strix or ROG Maximus motherboards running 8th or 9th Gen Intel processors should check the manufacturer portal for firmware patches. This update requires a manual BIOS flash process, which should be performed with caution to avoid system instability.
The takeaway
Maintaining firmware security is critical for hardware longevity, especially as older architectures face new physical vulnerability discoveries. Check the support portal for your specific motherboard model to confirm the latest BIOS version availability.
