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.
[Christian Brauner <[email protected]>: rewrite to account for watch
queues]
