  "details": "In the Linux kernel, the following vulnerability has been resolved:  iomap: don't free integrity payload that doesn't exist  fs_bio_integrity_alloc might not allocate a bio integrity payload if PI verification is disabled on the block device.  Check for that case before calling fs_bio_integrity_free in iomap_bio_read_folio_range_sync to avoid a NULL pointer dereferences.  Make the branch cover the PI verification as well - while fs_bio_integrity_verify works without an integrity payload, it requires one to actually do useful work.",
