Detail

In the Linux kernel, the following vulnerability has been resolved:

padata: do not leak refcount in reorder_work

A recent patch that addressed a UAF introduced a reference count leak: the parallel_data refcount is incremented unconditionally, regardless of the return value of queue_work(). If the work item is already queued, the incremented refcount is never decremented.

Fix this by checking the return value of queue_work() and decrementing the refcount when necessary.

Resolves:
