Description OSIDB Bzimport 2025-10-07 16:04:17 UTC 
In the Linux kernel, the following vulnerability has been resolved:

accel/qaic: Fix a leak in map_user_pages()

If get_user_pages_fast() allocates some pages but not as many as we
wanted, then the current code leaks those pages.  Call put_page() on
the pages before returning.
