CVE-2024-47680

CVE-2024-47680 affects the Linux kernel’s f2fs discard handling for conventional zones on zoned block devices. The root cause is that f2fs relied on a discard capability check performed by bdev_max_discard_sectors() and bdev_is_zoned(), which bypasses to discard even when a device doesn’t support...
