How to fix?

Upgrade SLES:16.0.0 kernel-docs-html to version 6.12.0-160000.9.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-docs-html package and not the kernel-docs-html package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

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:

    i2c i2c-2: IMX I2C adapter registered

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.
