Описание
In the Linux kernel, the following vulnerability has been resolved:
f2fs: fix to tag gcing flag on page during block migration
It needs to add missing gcing flag on page during block migration,
in order to garantee migrated data be persisted during checkpoint,
otherwise out-of-order persistency between data and node may cause
data corruption after SPOR.
Similar issue was fixed by commit 2d1fe8a86bf5 ("f2fs: fix to tag
gcing flag on page during file defragment").
A vulnerability was found in the Linux kernel's f2fs component, caused by a missing gflag on a page during block migration, something that is necessary to guarantee migrate data is persisted during checkpoint. Without this flag, it is possible that the data may not be properly persisted and can lead to data corruption after a sudden power-off recovery (SPOR).
Отчет
Red Hat Enterprise Linux 8 and 9 are not affected by this vulnerability.
