- Summary
- block: fix memory leak in disk_register_independent_access_ranges
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
block: fix memory leak in diskregisterindependentaccessranges
kobjectinitandadd() takes reference even when it fails. According to the doc of kobjectinitandadd()
If this function returns an error, kobject_put() must be called to properly clean up the memory associated with the object.
Fix this issue by adding kobjectput(). Callback function blkiarangessysfsrelease() in kobjectput() can handle the pointer "iars" properly.
