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

Description A memory leak occurs in the k3-socinfo component of the TI SoC (System on Chip) driver. The mmio regmap allocated during the probe process is not freed when a probe failure occurs, such as during probe deferral, or when the driver is unbound.

Recommendations Switch to using the device managed allocator to ensure the regmap is released on probe failures and during driver unbind.
