CVE-2023-52926

EUVD-2025-4375
In the Linux kernel, the following vulnerability has been resolved:

IORING_OP_READ did not correctly consume the provided buffer list when
read i/o returned < 0 (except for -EAGAIN and -EIOCBQUEUED return).
This can lead to a potential use-after-free when the completion via
io_rw_done runs at separate context.
