Description
In the Linux kernel, the following vulnerability has been resolved: thermal/drivers/hisi: Drop second sensor hi3660 The commit 74c8e6bffbe1 ("driver core: Add __alloc_size hint to devm allocators") exposes a panic "BRK handler: Fatal exception" on the hi3660_thermal_probe funciton. This is because the function allocates memory for only one sensors array entry, but tries to fill up a second one. Fix this by removing the unneeded second access.

Executive Summary

This vulnerability occurs in the Linux kernel's thermal driver for the hi3660 sensor. A recent commit introduced a panic due to the driver allocating memory for only one sensor array entry but attempting to access a second one, causing a fatal exception. The fix involved removing the unnecessary second access to prevent this panic.

Impact Analysis

This vulnerability can cause the Linux kernel to panic and crash when the hi3660 thermal driver tries to access a second sensor entry that was not properly allocated. This can lead to system instability or downtime on affected devices.
