Estado: ModificadaMedia (5.5)—

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

net: 9p: fix refcount leak in p9_read_work() error handling

p9_req_put need to be called when m->rreq->rc.sdata is NULL to avoid temporary refcount leak.

[Dominique: commit wording adjustments, p9_req_put argument fixes for rebase]
