Detailsinfo

A vulnerability was found in Linux Kernel up to 7.2.5. It has been classified as very critical. Affected is an unknown part of the component remoteproc. The manipulation with an unknown input leads to a out-of-bounds vulnerability. CWE is classifying the issue as CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: remoteproc: qcom_wcnss: Fix handling the lack of PD regulators in v3 The changes introduced to handle single power domain platforms have swapped the info pointer increment from num_pd_vregs to num_pds, which would shift the info pointer past the end of the array for pronto-v3, which does not list power domain regulators in vregs. This showed up as a difference between GCC- and LLVM-compiled kernels on SDM632 devices, where only with LLVM one would get the "regulator request with no identifier" error, because the out-of-bounds memory ended up being zeroed. Fix by skipping the increment when there are more power domains than regulators.

The advisory is shared for download at git.kernel.org. This vulnerability is traded as CVE-2026-93272 since 09/17/2026. The exploitability is told to be easy. The attack needs to be approached locally. Additional levels of successful authentication are needed for exploitation. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 09/24/2026).

Upgrading to version 7.2.6 or 7.3-rc1 eliminates this vulnerability. Applying the patch bce6b48af3abf7468d12ef4933f21bd8c1d822e9/3dbc90b9c22ea96e37bf55f6011e63b5123ec668 is able to eliminate this problem. The best possible mitigation is suggested to be upgrading to the latest version.
