the Linux kernel, the following vulnerability has been resolved:\n\ndm-crypt: fix a tiny race condition in crypt_dec_pending\n\ncrypt_dec_pending reads io->error before calling atomic_dec_and_test.\nAnother context, for example crypt_endio called from an interrupt, may\nset io->error and drop its reference between the read and the\ndecrement. crypt_dec_pending then drops the last reference and completes\nthe bio with the stale status - so a read that failed and was never\ndecrypted, or a write that failed, is reported as successful.\n\nThe read was placed before the decrement by commit b35f8caa0890 (\"dm\ncrypt: wait for endio to complete before destruction\"), because that\ncommit freed dm_crypt_io before calling bio_endio. This is no longer the\ncase, dm_crypt_io lives in the per-bio data now.\n\nRead io->error after atomic_dec_and_test instead. atomic_dec_and_test is\nfully ordered, so no additional barrier is needed."}], "lastModified": "2026-10-31T13:17:56.900", "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67"}
