CVE-2026-99023— power: sequencing: pcie-m2: Fix leaking array from of_regulator_bulk_get_all()

Quick assessment

Affected

Linux Linux

Exploitation

No confirmed in-the-wild exploitation; assess based on exposure

Recommended action

Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，以下漏洞已得到修复：电源管理：电源时序：PCIe M.2：修复由 of_regulator_bulk_get_all() 导致的数组内存泄漏问题。 of_regulator_bulk_get_all() 函数会分配一个 consumers 数组并将其交给调用者，调用者应在适当时机释放该数组。然而，pwrseq-pcie-m2.c 从未执行释放操作，从而导致了内存泄漏。现已添加显式的 kfree() 调用，用于释放该 consumers 数组。

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

Source: CVE Program / CVE List V5

Vulnerability Description

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.
