Detailsinfo

A vulnerability has been found in Linux Kernel up to 6.16-rc4 and classified as problematic. Affected by this vulnerability is the function drvdata::gpiods of the component regulator. The manipulation with an unknown input leads to a allocation of resources vulnerability. The CWE definition for the vulnerability is CWE-770. The product allocates a reusable resource or group of resources on behalf of an actor without imposing any restrictions on the size or number of resources that can be allocated, in violation of the intended security policy for that actor. The impact remains unknown. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: regulator: gpio: Fix the out-of-bounds access to drvdata::gpiods drvdata::gpiods is supposed to hold an array of 'gpio_desc' pointers. But the memory is allocated for only one pointer. This will lead to out-of-bounds access later in the code if 'config::ngpios' is > 1. So fix the code to allocate enough memory to hold 'config::ngpios' of GPIO descriptors. While at it, also move the check for memory allocation failure to be below the allocation to make it more readable.

It is possible to read the advisory at git.kernel.org. This vulnerability is known as CVE-2025-38395 since 04/16/2025. Technical details of the vulnerability are known, but there is no available exploit.
