CVE-2026-74733
A flaw was found in the Linux kernel's gpio: pca953x driver, which manages General Purpose Input/Output GPIO expanders. The driver uses its own locking mechanism, but the pca953xirqbussyncunlock function failed to acquire the necessary lock when performing register operations. This oversight coul...
SUSE CVE-2026-74733
In the Linux kernel, the following vulnerability has been resolved: gpio: pca953x: fix pca953xirqbussyncunlock regmap lock Locking is disabled in the regmap config as this driver uses its own lock. This means that all calls to regmap functions read or write must hold the i2clock. The function...

CVE-2026-74733
A race condition in the Linux kernel's gpio: pca953x driver (managing PCA953x GPIO expanders) allows concurrent threads to access hardware registers without proper locking. The function pca953x_irq_bus_sync_unlock() performed regmap read/write operations without holding the driver's i2c_lock , wh...

CVE-2025-38671
CVE-2025-38671 affects the Linux kernel i2c: qup driver. Root cause: timeout handling only set a return value and did not exit the loop when a client keeps the bus active, enabling kernel hang (observed with PCA953x GPIO extender). Fix: change the logic to return via -ETIMEDOUT, jumping out of th...
