AI-suggested

A fix has been implemented in the Linux kernel source code to correct the pointer increment logic in the qcom_wcnss remoteproc driver. Users should update to a kernel version that includes this fix once available. No additional mitigation steps are indicated.

Description

A vulnerability in the Linux kernel's remoteproc driver for Qualcomm WCNSS devices (pronto-v3) involved incorrect handling of power domain regulators. The issue caused an out-of-bounds memory access due to improper pointer increment logic, leading to errors on certain device compilations. This flaw has been fixed by adjusting the increment logic to correctly handle cases where there are more power domains than regulators.
