CVE-2024-48857Network attack vector

Process crash via PCX codec NULL dereference

Published Jan 14, 2025 · Updated Jan 14, 2025

NULL pointer dereference in the PCX image codec in BlackBerry QNX SDP 7.0, 7.1, and 8.0 allows remote attackers to crash its host process. The decoder follows a NULL pointer while parsing attacker-supplied PCX data rather than rejecting the invalid state. Exploitation requires a process to decode remotely supplied PCX data; the failure interrupts that process without reported data exposure or code execution.
