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().
Does this matter?
Lower severity and a low EPSS score (0.18%). Track it; it rarely justifies an emergency change on its own.
