Detailsinfo

A vulnerability classified as problematic was found in Linux Kernel up to 6.12.1. Affected by this vulnerability is the function platform_get_irq of the component mfd. The impact remains unknown. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: mfd: intel_soc_pmic_bxtwc: Use IRQ domain for USB Type-C device While design wise the idea of converting the driver to use the hierarchy of the IRQ chips is correct, the implementation has (inherited) flaws. This was unveiled when platform_get_irq() had started WARN() on IRQ 0 that is supposed to be a Linux IRQ number (also known as vIRQ). Rework the driver to respect IRQ domain when creating each MFD device separately, as the domain is not the same for all of them.

The advisory is shared at git.kernel.org. This vulnerability is known as CVE-2024-56691 since 12/27/2024. Technical details are known, but no exploit is available.

The vulnerability scanner Nessus provides a plugin with the ID 216224 (Oracle Linux 7 / 8 : Unbreakable Enterprise kernel (ELSA-2025-20100)), which helps to determine the existence of the flaw in a target environment.
