In the Linux kernel, the following vulnerability has been resolved:
block: fix integer overflow in BLKSECDISCARD
I independently rediscovered
commit 22d24a544b0d49bbcbd61c8c0eaf77d3c9297155
block: fix overflow in blk_ioctl_discard()
but for secure erase.
Same problem:
uint64_t r[2] = {512, 18446744073709551104ULL};
ioctl(fd, BLKSECDISCARD, r);
will enter near infinite loop inside blkdev_issue_secure_erase():
a.out: attempt to access beyond end of device
loop0: rw=5, sector=3399043073, nr_sectors = 1024 limit=2048
bio_check_eod: 3286214 callbacks suppressed
