Detailsinfo

A vulnerability classified as problematic was found in Linux Kernel up to 6.18.39/7.1.4/7.2-rc3. This vulnerability affects the function esdhc_change_pinstate of the component sdhci-esdhc-imx. The manipulation with an unknown input leads to a state issue vulnerability. The CWE definition for the vulnerability is CWE-371. As an impact it is known to affect integrity, and availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: mmc: sdhci-esdhc-imx: fix esdhc_change_pinstate() to allow default state restore esdhc_change_pinstate() checks for pins_100mhz and pins_200mhz at the top of the function and returns -EINVAL if either is not defined. This prevents the default case from ever being reached, which means devices with a sleep pinctrl state but without high-speed pin states (100mhz/ 200mhz) can never restore their default pin configuration. Move the IS_ERR checks for pins_100mhz and pins_200mhz into their respective switch cases.

The advisory is shared for download at git.kernel.org. This vulnerability was named CVE-2026-68465 since 07/30/2026. The exploitation appears to be easy. The attack can be initiated remotely.
