[SRU][Mantic][PATCH 0/1] CVE-2023-6560

[Yuxuan Luo]

[Impact]
It has been found that io_uring lacks checking user allocated
discontigous pages in io_uring.c which is not supported at the moment.
Failing to do so might leads to out-of-bound read, leading to potential
memory leak or system crash.

[Backport]
It is a clean cherry pick.

[Test]
Tested against test suite in liburing.

[Potential Regression]
Regression might occur when users allocating memory for their
application using io_uring.
