CVE-2026-64236

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

Description A division-by-zero issue exists in the i2c davinci driver. When the clock-frequency property is missing from the device tree, the driver uses the DAVINCI I2C DEFAULT BUS FREQ macro. Because this macro was defined in kHz (100) instead of Hz, the probe function's division by 1000 caused integer truncation, resulting in the dev->bus freq variable being set to 0. This leads to a deterministic kernel panic during the calculation of clock dividers later in the probe sequence.

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