Negotiating with Ransomware Gangs

Really interesting conversation with someone who negotiates with ransomware gangs: For now, it seems that paying ransomware, while obviously risky and empowering/encouraging ransomware attackers, can perhaps be comported so as not to break any laws like anti-terrorist laws, FCPA, conspiracy and...

kernel: memory leak in mwifiex_tm_cmd in drivers/net/wireless/marvell/mwifiex/cfg80211.c

A flaw was found in the Linux kernel's mwifiex driver implementation when connecting to other WiFi devices in "Test Mode." A kernel memory leak can occur if an error condition is met during the parameter negotiation. This issue can lead to a denial of service if multiple error conditions meeting...

The client side in OpenSSH 5.7 through 8.4 has an Observable Discrepancy leading to an information leak in the algorithm negotiation. This allows man-in-the-middle attackers to target initial connection attempts (where no host key for the server has been cached by the client). NOTE: some reports state that 8.5 and 8.6 are also affected.
