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.
AnalysisAI
Denial of service via null pointer dereference in Linux kernel gpio-qixis-fpga driver affects local users with limited privileges. The driver incorrectly checks for NULL return value from devm_regmap_init_mmio(), which returns ERR_PTR() on failure, allowing a local attacker with user-level privileges to trigger a kernel panic by causing improper error handling. …
