CVE-2025-68222
Estado: AplazadaSin puntuar—
In the Linux kernel, the following vulnerability has been resolved:
pinctrl: s32cc: fix uninitialized memory in s32_pinctrl_desc
s32_pinctrl_desc is allocated with devm_kmalloc(), but not all of its fields are initialized. Notably, num_custom_params is used in pinconf_generic_parse_dt_config(), resulting in intermittent allocation errors, such as the following splat when probing i2c-imx:
This results in later parse failures that can cause issues in dependent drivers:
Fix this by initializing s32_pinctrl_desc with devm_kzalloc() instead of devm_kmalloc() in s32_pinctrl_probe(), which sets the previously uninitialized fields to zero.
