Description OSIDB Bzimport 2026-07-24 16:03:13 UTC 
In the Linux kernel, the following vulnerability has been resolved:

Input: elan_i2c - validate firmware size before use

Ensure that the firmware file is large enough to contain the expected
number of pages and the signature (which resides at the end of the
firmware blob) before accessing them to prevent potential out-of-bounds
reads.
