CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's f2fs file system, where a failure to submit read bio requests for large folios can lead to indefinite waits for read completions when errors occur. This issue can result in degraded system performance and potential denial of service for applications relying on file reads. System administrators and developers using Linux with f2fs should prioritize applying the patch to mitigate these risks.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: f2fs: fix missing read bio submission on large folio error f2fs_read_data_large_folio() can keep a read bio across multiple readahead folios. If a later folio hits an error before any of its blocks are added to the bio, folio_in_bio is false and the current error path returns immediately after ending that folio. This can leave the bio accumulated for earlier folios unsubmitted. Those folios then never receive read completion, and readers can wait indefinitely on the locked folios. Route errors through the common out path so any pending bio is submitted before returning. Stop consuming more readahead folios once an error is seen, and only wait on and clear the current folio when it was actually added to the bio.
