CVE-2026-41647: CWE-476: NULL Pointer Dereference in lxc incus
CVE-2026-41647 is a medium-severity vulnerability in the Incus container and virtual machine manager prior to version 7. 0. 0. It involves a NULL pointer dereference caused by missing error handling when an authenticated user imports a truncated storage bucket backup file, leading to a daemon crash. This denial-of-service condition affects availability but does not impact confidentiality or integrity. The issue has been addressed in Incus version 7. 0. 0.
AI Analysis
Technical Summary
Incus versions before 7.0.0 contain a NULL pointer dereference vulnerability (CWE-476) due to insufficient error handling during the import of truncated storage bucket backup files by authenticated users. This flaw can cause the Incus daemon to crash, resulting in a denial-of-service. The vulnerability has a CVSS 3.1 base score of 6.5, reflecting network attack vector, low attack complexity, required privileges, no user interaction, unchanged scope, and impact limited to availability. The issue is fixed in version 7.0.0.
Potential Impact
An authenticated user can cause the Incus daemon to crash by importing a malformed truncated backup file, leading to denial-of-service. There is no impact on confidentiality or integrity. No known exploits are reported in the wild.
