In the Linux kernel, the following vulnerability has been resolved: mfd: sm501: Fix potential memory leaks during remove The memory allocated for… (CVE-2026-80974)
A vulnerability in the Linux kernel's mfd: sm501 driver involved potential memory leaks during device removal. Specifically, memory allocated for struct sm501_devdata in the probe functions was not freed in the corresponding remove functions. This issue has been fixed by adding calls to kfree() to properly release allocated memory.
AI Analysis
Technical Summary
The Linux kernel's mfd: sm501 driver had a memory management flaw where memory allocated in sm501_pci_probe() and sm501_plat_probe() was not freed in sm501_pci_remove() and sm501_plat_remove(), causing potential memory leaks. The fix involves adding kfree() calls in the remove functions to release the allocated struct sm501_devdata memory.
Potential Impact
The vulnerability could lead to memory leaks in the kernel when devices using the sm501 driver are removed. While this does not directly indicate a security compromise such as code execution or privilege escalation, memory leaks can degrade system stability and performance over time.
Mitigation Recommendations
A fix has been implemented in the Linux kernel to address this issue by adding kfree() calls in the remove functions. Users should update to the patched kernel version once available. Patch status is not explicitly confirmed in the provided data; check the vendor advisory for current remediation guidance.
