Description OSIDB Bzimport 2025-06-18 10:02:37 UTC 
In the Linux kernel, the following vulnerability has been resolved:

dmaengine: idxd: fix memory leak in error handling path of idxd_alloc

Memory allocated for idxd is not freed if an error occurs during
idxd_alloc(). To fix it, free the allocated memory in the reverse order
of allocation before exiting the function in case of an error.
