CVE-2024-35997

In the Linux kernel, the following vulnerability has been resolved: HID: i2c-hid: remove I2C_HID_READ_PENDING flag to prevent lock-up The flag I2C_HID_READ_PENDING is used to serialize I2C operations. However, this is not necessary, because I2C core already has its own locking for that. More importantly, this flag can cause a lock-up: if the flag is set in i2c_hid_xfer() and an interrupt happens, the interrupt handler (i2c_hid_irq) will check this flag and return immediately without doing anything, then the interrupt handler will be invoked again in an infinite loop. Since interrupt handler is an RT task, it takes over the CPU and the flag-clearing task never gets scheduled, thus we have a lock-up. Delete this unnecessary flag.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: HID: i2c-hid: elimine el indicador I2C_HID_READ_PENDING para evitar el bloqueo. El indicador I2C_HID_READ_PENDING se utiliza para serializar operaciones I2C. Sin embargo, esto no es necesario, porque el núcleo I2C ya tiene su propio bloqueo para ello. Más importante aún, este indicador puede causar un bloqueo: si el indicador está configurado en i2c_hid_xfer() y ocurre una interrupción, el controlador de interrupciones (i2c_hid_irq) verificará este indicador y regresará inmediatamente sin hacer nada, entonces se invocará el controlador de interrupciones. nuevamente en un bucle infinito. Dado que el controlador de interrupciones es una tarea RT, se hace cargo de la CPU y la tarea de limpieza de banderas nunca se programa, por lo que tenemos un bloqueo. Elimine esta bandera innecesaria.
