CVE-2026-80680

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the amd-mp2 I2C driver where the amd mp2 register cb() function stores the platform I2C context in the MP2 PCI driver callback table before the adapter is registered. If the i2c add adapter() function fails, the probe process returns and the device resource manager frees the context. However, the PCI driver may still attempt to dereference this stale pointer during IRQ and system-sleep callbacks, potentially leading to a system crash.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
