CVE-2023-53810

CVE-2023-53810 is a Linux kernel race condition in the blk-mq/keyslot path. After I/O using a blk_crypto_key completes, keyslot release was delayed until request free, potentially allowing blk_crypto_evict_key() to observe non-zero slot_refs while there is no active bug. The vulnerability manifes...
