  "details": "In the Linux kernel, the following vulnerability has been resolved:  dm-crypt: fix a tiny race condition in crypt_dec_pending  crypt_dec_pending reads io-\u003eerror before calling atomic_dec_and_test. Another context, for example crypt_endio called from an interrupt, may set io-\u003eerror and drop its reference between the read and the decrement. crypt_dec_pending then drops the last reference and completes the bio with the stale status - so a read that failed and was never decrypted, or a write that failed, is reported as successful.  The read was placed before the decrement by commit b35f8caa0890 (\"dm crypt: wait for endio to complete before destruction\"), because that commit freed dm_crypt_io before calling bio_endio. This is no longer the case, dm_crypt_io lives in the per-bio data now.  Read io-\u003eerror after atomic_dec_and_test instead. atomic_dec_and_test is fully ordered, so no additional barrier is needed.",
