Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: A missing key size check in L2CAPLECONNREQ has been fixed. A check for the encryption key size is added upon receiving the L2CAPLECONNREQ. This is required by L2CAP/LE/CFC/BV-15-C, which expects...

CVE-2026-19293: Weak Password Requirements

SMP security request from peripheral does not include the maximum encryption key size supported. Using a key with less than the maximum keysize makes brute-forcing the key easier. See V6 in BLERP paper linked below...

CVE-2026-43134

A flaw was found in the Linux kernel's Bluetooth Low Energy LE Logical Link Control and Adaptation Protocol L2CAP. A missing check for encryption key size when processing connection requests could allow a remote attacker to send a malformed request. This could lead to a protocol violation,...
