- Summary
- xfs: don't wrap around quota ids in dqiterate
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
xfs: don't wrap around quota ids in dqiterate
LOLLM noticed that qid is an unsigned 32-bit variable. If it happens to be set to XFSDQIDMAX due to a filesystem that actually has a dquot for ID_MAX, then this addition will truncate to zero and the iteration starts over. Fix this by casting to u64.
