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-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-2026-74731

CVE-2026-74731 is a use-after-free vulnerability in the Linux kernel's sched_ext (extensible scheduler) component. When a sub-scheduler enable fails before scx_link_sched() links it into the hierarchy, the cleanup path still runs the full scx_sub_disable(). This creates a race against root disabl...
