Summary

In the Linux kernel, the following vulnerability has been resolved:

wifi: iwlwifi: fix counter type in iwl_fwrt_dump_error_logs

The loop counter 'count' was declared as u8 while num_pc is u32. If firmware advertises more than 255 PC entries the counter wraps back to zero and the loop never terminates potentially causing an infinite loop or reading past the allocated pc_data array.

Change the declaration to u32 to match num_pc.
