CVE-2026-54634
HighCVSS 7.3Exploitation Probability (EPSS)
Low risk36th percentile - higher than 36% of all known CVEs
Summary
In Hamlib prior to 4.7.2, the unauthenticated rigctld send_raw command on TCP port 4532 triggers an out-of-bounds stack write (NUL byte past a 200-byte buffer) and an oversized copy of uninitialized stack data. Under the default no-password configuration, a remote client can trigger both flaws with a single command.
Risk Assessment
A remote attacker can crash the daemon or corrupt adjacent stack memory, and can leak up to 198 bytes of uninitialized stack data. This may lead to denial of service or information disclosure.
Recommendation
Upgrade Hamlib to version 4.7.2 or later. Until then, consider restricting access to port 4532 and enabling authentication in rigctld.

Original NVD description (English source)
Hamlib is a ham radio control library for radios, rotators, and amplifiers. Prior to 4.7.2, the unauthenticated rigctld send_raw command on TCP port 4532 reaches rigctl_send_raw() in tests/rigctl_parse.c, which writes a NUL byte at buf[buf_len + 1] outside its 200-byte stack buffer, and rig_send_raw() in src/rig.c, which copies reply_len - 1 bytes instead of the actual nbytes received. A remote client can send the CR terminator with a short payload to trigger both flaws in one command under the default no-password configuration. The out-of-bounds write can crash the daemon or corrupt adjacent stack memory, while the oversized copy can return up to 198 bytes of uninitialized stack data to the client. This issue is fixed in version 4.7.2.
