- ntfs: fix kmap_local leak in write_mft_record_nolock() error paths
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
ntfs: fix kmap_local leak in write_mft_record_nolock() error paths
write_mft_record_nolock() maps the MFT record folio with kmap_local_folio(), but the pre_write_mst_fixup() and bio_add_folio() failure paths jump to the error label without unmapping it. kmap_local mappings are stack-ordered per task, so leaking one corrupts the nesting for any outer mapping.
Unmap the folio on those error paths too.
