CVE-2026-93272
Full vulnerability record from the local CVENow database.
Description
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.
