What to do
AI-suggested
A fix is available in the Linux kernel to properly handle error returns from devm_regmap_init_mmio() by using IS_ERR() and PTR_ERR() macros. Users should apply the official Linux kernel update that includes this correction. No additional mitigation steps are indicated.
Description
A vulnerability in the Linux kernel's gpio qixis-fpga driver was fixed by correcting error handling for the devm_regmap_init_mmio() function. The function returns an ERR_PTR() on failure, but the original code incorrectly checked for NULL, which never occurs on error. This could lead to an invalid pointer dereference.
