CVE-2023-54041

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> io_uring: fix memory leak when removing provided buffers<br /> <br /> When removing provided buffers, io_buffer structs are not being disposed<br /> of, leading to a memory leak. They can&amp;#39;t be freed individually, because<br /> they are allocated in page-sized groups. They need to be added to some<br /> free list instead, such as io_buffers_cache. All callers already hold<br /> the lock protecting it, apart from when destroying buffers, so had to<br /> extend the lock there.
