    CVE-2025-34457 (GCVE-0-2025-34457)

    Vulnerability from cvelistv5 – Published: 2025-12-22 21:30 – Updated: 2026-03-23 15:43

    Title
    wb2osz/direwolf <= 1.8.1 Stack-based Buffer Overflow DoS
    Summary
    wb2osz/direwolf (Dire Wolf) versions up to and including 1.8, prior to commit 694c954, contain a stack-based buffer overflow vulnerability in the function kiss_rec_byte() located in src/kiss_frame.c. When processing crafted KISS frames that reach the maximum allowed frame length (MAX_KISS_LEN), the function appends a terminating FEND byte without reserving sufficient space in the stack buffer. This results in an out-of-bounds write followed by an out-of-bounds read during the subsequent call to kiss_unwrap(), leading to stack memory corruption or application crashes. This vulnerability may allow remote unauthenticated attackers to trigger a denial-of-service condition.

    CVE-2025-34458 (GCVE-0-2025-34458)

    Vulnerability from cvelistv5 – Published: 2025-12-22 21:29 – Updated: 2026-03-23 15:43
    VLAI
    Title
    wb2osz/direwolf <= 1.8.1 Reachable Assertion DoS
    Summary
    wb2osz/direwolf (Dire Wolf) versions up to and including 1.8, prior to commit 3658a87, contain a reachable assertion vulnerability in the APRS MIC-E decoder function aprs_mic_e() located in src/decode_aprs.c. When processing a specially crafted AX.25 frame containing a MIC-E message with an empty or truncated comment field, the application triggers an unhandled assertion checking for a non-empty comment. This assertion failure causes immediate process termination, allowing a remote, unauthenticated attacker to cause a denial of service by sending malformed APRS traffic.
