CVE-2024-40962

A NULL pointer dereference was found in the btrfs_zone_finish_endio() function in the Linux Kernel during the execution of test-case btrfs/167 on emulated zoned devices. This issue stems from missing checksum lists for NOCOW writes in zoned mode, as revealed by an assertion failure. The problem occurs because dummy checksums are only attached for zone-append writes, not for NOCOW writes.
