Title
wifi: rtw89: Correct data type for scan index to avoid infinite loop
Summary
In the Linux kernel, the following vulnerability has been resolved: wifi: rtw89: Correct data type for scan index to avoid infinite loop A kernel soft lockup was observed during Wi-Fi scanning on the 6GHz band. The CPU becomes stuck in rtw89_hw_scan_add_chan_ax for over 20 seconds, leading to a system panic. RIP points to 0f b6 c3 (movzbl %bl, %eax), which zero-extends the low 8 bits of RBX into RAX. RBX (the counter i) has reached a huge value: 0x137466a1. watchdog: BUG: soft lockup - CPU#2 stuck for 26s!
