# CVE-2026-89837

> 3.1 LOW

## Beschreibung

In the Linux kernel, the following vulnerability has been resolved:

f2fs: fix dentry folio leak in find_in_level

find_in_level() gets a dentry folio with f2fs_find_data_folio() before
calling find_in_block().  If find_in_block() returns an error, the
function stores the error in res_folio and breaks out of the loop without
dropping the dentry folio.

This leaks the folio reference on the find_in_block() error path.  Drop
the dentry folio before returning the error to the caller.

## Patch verfügbar (OSV)

- Kernel ≥ 6.18.51
- Kernel ≥ 7.2.5
