AI-suggested

A fix has been implemented to ensure the SRAM size is set to zero on mapping failure, preventing improper SRAM access. Users should update to patched linux-hwe-edge kernel versions that address this issue. Patch status is not explicitly stated, but the vulnerability is described as resolved in the affected versions.

Description

A vulnerability in the Linux kernel's ethosu accelerator driver causes the SRAM size to remain non-zero after a mapping failure. This can lead to jobs accessing SRAM incorrectly, as the probe does not check the error return and assumes SRAM is available. This issue has been resolved in the linux-hwe-edge kernel versions listed.
