CVE-2021-46984

CVE-2021-46984 : Linux kernel kyber driver had an out-of-bounds read due to a race between blk_mq_get_ctx() calls when a thread is preempted, causing ctx->index_hw[hctx->type] to differ from hctx. The fix passes the request_queue to kyber_bio_merge() (via ->bio_merge()) so Kyber can map ...

Apple Announces Post-Quantum Encryption Algorithms for iMessage

Apple announced PQ3, its post-quantum encryption standard based on the Kyber secure key-encapsulation protocol, one of the post-quantum algorithms selected by NIST in 2022. Theres a lot of detail in the Apple blog post, and more in Douglas Stabilas security analysis. I am of two minds about this...

Apple Unveils PQ3 Protocol - Post-Quantum Encryption for iMessage

Apple has announced a new post-quantum cryptographic protocol called PQ3 that it said will be integrated into iMessage to secure the messaging platform against future attacks arising from the threat of a practical quantum computer. "With compromise-resilient encryption and extensive defenses...
