gpsd 安全漏洞

gpsd is a daemon program for receiving GPS data. A security vulnerability exists in gpsd that stems from an integer underflow in the nextstate function, which could lead to 100% CPU utilization and a denial of service...

CVE-2025-67269

CVE-2025-67269 describes an integer underflow in gpsd/packet.c:nextstate() during NAVCOM packet parsing. The payload length is computed as lexer->length = (size_t)c - 4 without validating that c >= 4, causing an unsigned underflow to a very large value and a loop that can exhaust CPU (DoS)....

CVE-2025-67269

An integer underflow vulnerability exists in the nextstate function in gpsd/packet.c of gpsd versions prior to commit ffa1d6f40bca0b035fc7f5e563160ebb67199da7. When parsing a NAVCOM packet, the payload length is calculated using lexer-length = sizetc - 4 without checking if the input byte c is le...
