Vulnerability from github – Published: 2024-12-27 15:31 – Updated: 2025-01-16 18:30In the Linux kernel, the following vulnerability has been resolved:
io_uring: check for overflows in io_pin_pages

io_pin_pages()'s uaddr parameter came directly from the user and can be garbage. Don't just add size to it as it can overflow.
