Description

A flaw was found in the f2fs file system within the Linux kernel. This vulnerability occurs because certain ioctl interfaces, such as f2fs_ioc_set_pin_file(), f2fs_move_file_range(), and f2fs_defragment_range(), do not properly check the atomic write status. This oversight can lead to a race condition, potentially allowing a local attacker to cause a denial of service.
