- Summary
- btrfs: add the missing error handling inside get_canonical_dev_path
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
btrfs: add the missing error handling inside getcanonicaldev_path
Inside function getcanonicaldevpath(), we call dpath() to get the final device path.
But d_path() can return error, and in that case the next strscpy() call will trigger an invalid memory access.
Add back the missing error handling for d_path().
