CVE-2026-74733

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> gpio: pca953x: fix pca953x_irq_bus_sync_unlock regmap lock<br /> <br /> Locking is disabled in the regmap config as this driver uses its own<br /> lock. This means that all calls to regmap functions (read or write) must<br /> hold the i2c_lock. The function pca953x_irq_bus_sync_unlock() did not do<br /> this, and it was therefore possible that multiple threads could cause an<br /> incorrect register to be read/written.<br /> <br /> A previous patch partly fixed this, but only protected the write to the<br /> interrupt mask register, and not the read from the direction register.
