New Passkey Attacks Can Recover Synced Private Keys or Bypass Phishing-Resistant MFA

Three separate research efforts last week demonstrated ways to defeat passkey protections without breaking the cryptography they rest on. Passkeys are designed to replace reusable passwords and resist phishing. The attacks instead reused signed authentication material that Windows had exposed,...

CVE-2026-68301

The CVE-2026-68301 entry details a Linux kernel net: hsr memory leak where, on slave unregistration, VLAN IDs synced to the slave (including VID 0) are not deleted, leaving vlan_info/vlan_vid_info refs and causing a leak when the slave is destroyed. The fix adds vlan_vids_del_by_dev(port->dev,...

CVE-2026-68301 net: hsr: fix memory leak on slave unregistration by removing synced VLANs

In the Linux kernel, the following vulnerability has been resolved: net: hsr: fix memory leak on slave unregistration by removing synced VLANs When an HSR master device is brought UP, it auto-adds VLAN 0 via vlanvid0add, which propagates VID 0 to its slave devices slave A and B. If a slave device...

CVE-2026-39846

SiYuan is a personal knowledge management system. Prior to 3.6.4, a malicious note synced to another user can trigger remote code execution in the SiYuan Electron desktop client. The root cause is that table caption content is stored without safe escaping and later unescaped into rendered HTML,...

CVE-2026-45787 electerm's encrypt method not safe enough

electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client. Prior to 3.9.5, deterministic AES-192-CBC with a fixed zero IV, constant KDF salt, and no MAC leads to confidentiality and integrity failures for synced bookmark/profile data. Attackers can crack common...

CVE-2026-39901

Summary: CVE-2026-39901 affects the monetr budgeting app. Before version 1.12.3, an authenticated tenant user can use the transaction update (PUT) endpoint to soft-delete synced non-manual transactions, bypassing the intended protection that blocks deletion via the normal DELETE path. This is a s...
