CVE-2026-43008
Published: May 1, 2026· Updated: May 7, 2026
Official Description
In the Linux kernel, the following vulnerability has been resolved:
gpio: qixis-fpga: Fix error handling for devm_regmap_init_mmio()
devm_regmap_init_mmio() returns an ERR_PTR() on failure, not NULL.
The original code checked for NULL which would never trigger on error,
potentially leading to an invalid pointer dereference.
Use IS_ERR() and PTR_ERR() to properly handle the error case.
