CVE-2026-64237 Details
Description
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.
A vulnerability has been identified in the Linux kernel's elan_i2c driver, where the firmware size is not properly validated before use. This issue can lead to out-of-bounds read operations. The vulnerability exists in the stable branch of the Linux kernel. The problem arises because the driver does not ensure that the firmware file is sufficiently large to accommodate the expected number of pages and the signature, which is located at the end of the firmware blob. As a result, there is a risk of accessing memory outside the intended bounds, potentially leading to information disclosure or other unintended behavior.
Users can upgrade to the patched version of the Linux kernel where this vulnerability has been addressed. The official Linux kernel Git repository can be used to download the latest stable version.
