Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: Validate data run offset
This adds sanity checks for data run offset. We should make sure data run offset is legit before trying to unpack them, otherwise we may encounter use-after-free or some unexpected memory access behaviors.
