AI-suggested

A fix for this vulnerability has been implemented in the Linux kernel. Users should update to the fixed versions identified by the provided commit hashes to remediate the issue.

Description

A vulnerability in the Linux kernel elan_i2c input driver was addressed by validating the firmware size before use. The fix ensures the firmware file is sufficiently large to contain the expected number of pages and the signature at the end of the firmware blob, preventing out-of-bounds reads.
