Details

In the Linux kernel, the following vulnerability has been resolved:

iommufd: Fix outfput in iommufdfault_alloc()

As fput() calls the file->fop->release 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: refcountt: decrement hit 0; leaking memory. WARNING: CPU: 48 PID: 2369 at lib/refcount.c:31 refcountwarnsaturate+0x60/0x230 Call trace: refcountwarnsaturate+0x60/0x230 (P) refcountwarnsaturate+0x60/0x230 (L) iommufdfaultfopsrelease+0x9c/0xe0 [iommufd] ...
