CVE-2026-64258
|
| Sažetak |
In the Linux kernel, the following vulnerability has been resolved:
fuse-uring: remove request-less entries from ent_w_req_queue to fix NULL deref
If a copy into the userspace ring buffer fails, a request will be
terminated and fuse_uring_req_end() will set ent->fuse_req to NULL but
it will leave the entry on ent_w_req_queue in FRRS_FUSE_REQ state. This
can lead to a NULL deref if the request expiration logic scans
ent_w_req_queue in the window before the entry is moved off it.
Fix this by taking the entry off ent_w_req_queue and changing its state
from FRRS_FUSE_REQ to FRRS_INVALID before terminating the request. |
