CVE-2026-89837

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.
