{"id":"DEBIAN-CVE-2024-56624","details":"In the Linux kernel, the following vulnerability has been resolved:  iommufd: Fix out_fput in iommufd_fault_alloc()  As fput() calls the file-\u003ef_op-\u003erelease op, where fault obj and ictx are getting released, there is no need to release these two after fput() one more time, which would result in imbalanced refcounts:   refcount_t: decrement hit 0; leaking memory.
