CVE-2026-43004
Description
A flaw was found in the Linux kernel's stm32-ospi driver. The remove() callback, which is intended to clean up resources, could exit prematurely under certain power management conditions. This issue prevents the proper release of SPI controller and other system resources, potentially leading to resource exhaustion. This could allow a local attacker to cause a Denial of Service (DoS).

Availability
Technical Impact: DoS: Resource Consumption (Other); DoS: Resource Consumption (Memory); DoS: Resource Consumption (CPU)
An attacker that can influence the allocation of resources that are not properly released could deplete the available resource pool and prevent all other processes from accessing the same type of resource. Frequently-affected resources include memory, CPU, disk space, power or battery, etc.
