Title
fs/aio: Restrict kiocb_set_cancel_fn() to I/O submitted via libaio
Summary
In the Linux kernel, the following vulnerability has been resolved:
fs/aio: Restrict kiocb_set_cancel_fn() to I/O submitted via libaio
If kiocb_set_cancel_fn() is called for I/O submitted via io_uring, the
following kernel warning appears:
WARNING: CPU: 3 PID: 368 at fs/aio.c:598 kiocb_set_cancel_fn+0x9c/0xa8
Call trace:
kiocb_set_cancel_fn+0x9c/0xa8
ffs_epfile_read_iter+0x144/0x1d0
io_read+0x19c/0x498
io_issue_sqe+0x118/0x27c
io_submit_sqes+0x25c/0x5fc

el0_svc+0x2c/0xa4
el0t_64_sync_handler+0x68/0xb4
el0t_64_sync+0x1a4/0x1a8
Fix this by setting the IOCB_AIO_RW flag for read and write I/O that is
submitted by libaio.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
