Descriptions
In the Linux kernel, the following vulnerability has been resolved:
pipe: wakeup wr_wait after setting max_usage
Commit c73be61cede5 ("pipe: Add general notification queue support") a
regression was introduced that would lock up resized pipes under certain
conditions. See the reproducer in [1].
The commit resizing the pipe ring size was moved to a different
function, doing that moved the wakeup for pipe->wr_wait before actually
raising pipe->max_usage. If a pipe was full before the resize occured it
would result in the wakeup never actually triggering pipe_write.
Set @max_usage and @nr_accounted before waking writers if this isn't a
watch queue.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: tubería: despertar wr_wait después de configurar max_usage Confirmar c73be61cede5 ("tubería: Agregar soporte de cola de notificaciones generales") se introdujo una regresión que bloquearía las tuberías redimensionadas bajo ciertas condiciones. Ver el reproductor en [1]. La confirmación de cambio de tamaño del anillo de tubería se movió a una función diferente, lo que movió la activación de pipe->wr_wait antes de aumentar pipe->max_usage. Si una tubería estaba llena antes de que ocurriera el cambio de tamaño, la reactivación nunca activaría pipe_write. Configure @max_usage y @nr_accounted antes de despertar a los escritores si no se trata de una cola de vigilancia. [Christian Brauner : reescribir en la cuenta para las colas de visualización]
