Vulnerability from github – Published: 2026-08-15 06:32 – Updated: 2026-08-15 06:32

Details

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.

Title

mmc: sdhci-esdhc-imx: fix esdhc_change_pinstate() to allow default state restore

Summary

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.
