Re: [BUG] NULL deref in mempool_free_bulk via crypt_endio on dm-crypt teardown (6.8 -> 7.0 regression)

[Léo Terziman]

Thanks for the pointer. I applied the mitigations we discussed (serialized dm-crypt teardown, nodiscard) and the panic reproduced again with an identical signature, attached. I looked up 83f7e52b7ed1c3e03b79123e20b6f6adf8d886bb and the closest match I can find is CVE-2026-93255 ("btrfs: make sure EXTENT_BUFFER_READING is cleared under refs_lock"), where that hash appears as the introduced commit rather than the fix — the actual fixes there are listed as 2073f3d97b0c5d34fe64812d1237e37bd79c17ec and 690c2accacb1aca91ab8186d15dee56da8723f31. Could you confirm whether that's the patch you meant, or point me to the right one?

I suspect that this is btrfs bug. It seems that btrfs closes a block
device without waiting for bios to finish.

The mempool_free function was reworked between 6.8 and 7.0. In 6.8 it
didn't crash if we attempted to free an entry into a free mempool. In 7.0
it crashes in this case. So, the btrfs bug could have been there forever,
it was just latent and didn't result in a crash on old kernels.

You can try to apply the patch 83f7e52b7ed1c3e03b79123e20b6f6adf8d886bb -
maybe it helps.
