Name of the Vulnerable Software and Affected Versions Linux kernel versions 3.x

Description The issue is caused by a stack-based buffer overflow in the supply lm input write function of the MSM Thermal driver. This can be exploited by sending a large amount of data through the debugfs interface, potentially allowing an attacker to cause a denial of service or have other unspecified impacts.

Recommendations For Linux kernel version 3.x, consider restricting access to the debugfs interface to minimize the risk of exploitation until a patch is available. As a temporary workaround, consider disabling the supply lm input write function in the MSM Thermal driver to prevent potential attacks.
