Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
fuse-uring: remove request-less entries from ent_w_req_queue to fix NULL deref<br />
<br />
If a copy into the userspace ring buffer fails, a request will be<br />
terminated and fuse_uring_req_end() will set ent->fuse_req to NULL but<br />
it will leave the entry on ent_w_req_queue in FRRS_FUSE_REQ state. This<br />
can lead to a NULL deref if the request expiration logic scans<br />
ent_w_req_queue in the window before the entry is moved off it.<br />
<br />
Fix this by taking the entry off ent_w_req_queue and changing its state<br />
from FRRS_FUSE_REQ to FRRS_INVALID before terminating the request.
