In the Linux kernel, the following vulnerability has been resolved:

md/raid10: reset read_slot when reusing r10bio for discard

put_all_bios() always drops devs[i].bio, but it only drops

devs[i].repl_bio when r10_bio->read_slot < 0. If discard reuses an

r10bio that was previously used for a read, read_slot can still be

non-negative, and discard cleanup can skip bio_put() on repl_bio.

Reset read_slot to -1 when preparing an r10bio for discard so the

replacement bio is always released correctly. (NVD)
