CVE-2023-53810

Summary: CVE-2023-53810 describes a race in the Linux kernel blk-mq crypto keyslot handling. When I/O completes, keyslots are not released until the request is freed, allowing blk_crypto_evict_key() to observe slot_refs != 0 even if there is no bug. This can trigger a use-after-free in blk_crypto...
