# Linux kernel: PCIe M.2 power sequencing leaks a regulator array

The Linux kernel's PCIe M.2 power sequencing driver allocates a regulator consumers array and never frees it, causing a memory leak. The fix adds an explicit kfree() for that array; the sources describe no code execution or data exposure.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

In the Linux kernel, the following vulnerability has been resolved:

power: sequencing: pcie-m2: Fix leaking array from of_regulator_bulk_get_all()

of_regulator_bulk_get_all() allocates the consumers array and hands it to
the caller, who is expected to free it at an appropriate time.
pwrseq-pcie-m2.c never did, leading to a memory leak.

Add an explicit kfree() for the consumers array.
