Certified Randomness Amplification by Dynamically Probing Remote Random Quantum States
Cryptography depends on truly unpredictable numbers, but physical sources emit biased or correlated bits. Quantum mechanics enables the amplification of imperfect randomness into nearly perfect randomness, but prior demonstrations have required physically co-located, loophole-free Bell tests,...
Is Protective DNS Blocking the Wild West?
We perform a passive measurement study investigating how a Protective DNS service might perform in a Research & Education Network serving hundreds of member institutions. Utilizing freely-available DNS blocklists consisting of domain names deemed to be threats, we test hundreds of millions of...

CVE-2022-50577
CVE-2022-50577 involves a memory leak in the Linux kernel’s IMA path. The root cause was that __ima_inode_hash() could allocate ima_hash and then fail after ima_collect_measurement() returned an error, allowing a leaked temporary inode metadata structure. The patch adds a kfree() when the error f...
