Summary
In the Linux kernel, the following vulnerability has been resolved:
Input: ims-pcu - add response length checks
The driver processes response data from device buffers without verifying that the device actually sent enough data. This can lead to out-of-bounds reads or processing stale data.
Add checks for the expected response length before accessing the buffers.
