- Summary
- iomap: release pages on atomic dio size mismatch
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
iomap: release pages on atomic dio size mismatch
If bioiovitergetpages() or the bounce helper succeeds but builds a short bio, the REQ_ATOMIC size check rejects it before submission. The old error path only dropped the bio reference, leaving any pages already attached to the bio unreleased.
Release or unbounce the pages before falling through to outputbio on this error path.
