CVE-2026-43004 Details
Description
In the Linux kernel, the following vulnerability has been resolved: spi: stm32-ospi: Fix resource leak in remove() callback The remove() callback returned early if pm_runtime_resume_and_get() failed, skipping the cleanup of spi controller and other resources. Remove the early return so cleanup completes regardless of PM resume result.
A resource leak vulnerability has been identified in the Linux kernel's SPI STM32 OSPI driver. The issue arises in the remove callback, which prematurely exits if the PM runtime resume operation fails. This early return prevents the proper cleanup of the SPI controller and other associated resources. The vulnerability affects the Linux kernel stable tree.
Users can apply the available patch in the Linux kernel stable tree to address this vulnerability. The patch is included in the official Linux Git repository.
