AlienVault OTX Vulnerabilities

AlienVault OTX Malware

Multiple vulnerabilities in the Bluetooth subsystem of the Linux Kernel prior to version 7.0.7 can lead to denial of service conditions. The Linux Kernel is the core component of the Linux operating system. These issues affect open source Linux Kernel versions before 7.0.7. No CVSS score is provided for these vulnerabilities.

This vulnerability (CVE-2026-45834) involves multiple security flaws in the Bluetooth component of the Linux Kernel, which could allow an attacker to cause denial of service. The affected software includes open source Linux Kernel versions earlier than 7.0.7. The advisory is published by the Bundesamt für Sicherheit in der Informationstechnik and referenced by the Microsoft Security Response Center. There is no detailed technical description or CVSS score available, and no known exploits in the wild have been reported.

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: Fix null-ptr-deref in l2cap_sock_state_change_cb() Add the same NULL guard already present in l2cap_sock_resume_cb() and l2cap_sock_ready_cb().

The Linux kernel contained a vulnerability in the Bluetooth L2CAP code, specifically in the function l2cap_sock_state_change_cb, where a null pointer dereference could occur. This was addressed by adding a NULL pointer check to prevent dereferencing a null pointer, aligning with protections already present in related callbacks (l2cap_sock_resume_cb and l2cap_sock_ready_cb). The vulnerability has a CVSS 3.1 base score of 5.5 (medium severity) with local attack vector, low attack complexity, low privileges required, no user interaction, unchanged scope, no confidentiality or integrity impact, but high impact on availability (kernel crash). Multiple Linux kernel versions prior to certain patched versions are affected. The vendor advisory from Ubuntu confirms the availability of patches and recommends updating to fixed kernel versions.
