Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2024-48857 is a NULL pointer dereference vulnerability (CWE-476) in the PCX image codec of QNX Software Development Platform (SDP) versions 8.0, 7.1, and 7.0. Published on January 14, 2025, it carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), indicating high severity due to its potential for significant availability impact.

An unauthenticated attacker can exploit this flaw remotely with low attack complexity and no privileges or user interaction required. Exploitation triggers a denial-of-service condition within the context of the process utilizing the image codec, potentially crashing the application without affecting confidentiality or integrity.

Security practitioners should consult the BlackBerry advisory at https://support.blackberry.com/pkb/s/article/140334 for details on patches and mitigation recommendations.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation (including static analysis) directly finds null-dereference bugs before deployment.

Documented development standards and tools can enforce null-safety rules and safe pointer usage.

Engineering principles can mandate defensive coding such as explicit null checks before dereference.
