CVE-2026-80605CVE-2026-80605
Description
In the Linux kernel, the following vulnerability has been resolved:
HID: picolcd: prevent NULL pointer dereference in picolcd_send_and_wait()
In picolcd_send_and_wait(), an integer overflow of the signed loop counter
'k' can theoretically lead to a NULL pointer dereference of 'raw_data'.
If the loop executes more than INT_MAX times, 'k' becomes negative,
making the condition 'k < size' true even when 'size' is 0.
Change the type of 'k' to 'unsigned int' to prevent the overflow and
eliminate the out-of-bounds access.
Found by Linux Verification Center (linuxtesting.org) with the Svace static
analysis tool.
