Detailsinfo

A vulnerability was found in Linux Kernel up to 6.12.1. It has been declared as problematic. This vulnerability affects the function platform_get_irq of the component mfd. The impact remains unknown. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: mfd: intel_soc_pmic_bxtwc: Use IRQ domain for PMIC devices 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 for download at git.kernel.org. This vulnerability was named CVE-2024-56723 since 12/27/2024. There are known technical details, 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.
