CVE-2026-53205 Details
Description
In the Linux kernel, the following vulnerability has been resolved: accel/ivpu: Add bounds checks for firmware log indices Add validation that read and write indices in the firmware log buffer are within valid bounds (< data_size) before using them. If out-of-bounds indices are encountered (from firmware), clamp them to safe values instead of proceeding with invalid offsets. This prevents potential out-of-bounds buffer access when firmware supplies invalid log indices.
A vulnerability in the Linux kernel's IVPU driver has been addressed, which involved improper handling of firmware log indices. The issue arose because the driver did not validate read and write indices before using them, potentially leading to out-of-bounds buffer access. The vulnerability has been fixed by adding checks to ensure that these indices are within valid limits. If an index is found to be out of bounds, it is clamped to a safe value instead of allowing the use of invalid offsets. This change prevents possible exploitation when firmware provides incorrect log index data.
