CVE-2026-88781
MediumCVSS 6.8Exploitation Probability (EPSS)
Low risk1th percentile - higher than 1% of all known CVEs
Summary
An untrusted pointer dereference in the firmware of certain ASUS motherboards allows a kernel-level privileged user to supply an arbitrary memory address via an I/O command, leading to tampering with system information or a system crash.
Risk Assessment
A kernel-privileged user could corrupt system data or cause a crash, affecting system stability and integrity. The attack requires high privileges, which limits the attack vector.
Recommendation
Apply the security update for ASUS motherboards as described in the ASUS Security Advisory. Restrict kernel-level privileges to trusted users.
