Affects Feature Release versions 7.7.1.0-8.6, LTS2025 (8.3.1.0-8.3.1.10), and LTS2024 (7.13.1.0-7.13.1.60). Despite network-accessible attack vector (AV:N/PR:N), high attack complexity (AC:H) indicates specialized exploit conditions. CISA SSVC framework rates exploitation as 'none' and automatable as 'no', suggesting manual, targeted exploitation rather than mass scanning. No active exploitation confirmed at time of analysis. Dell has released patches across all affected release tracks (DSA-2026-060).

Stack buffer overflow in PJSIP (pjproject) 2.16 and earlier occurs in pjsip_auth_create_digest2() when an application authenticates using pre-computed digest credentials (PJSIP_CRED_DATA_DIGEST). The function pj_memcpy's cred_info->data.slen bytes into a fixed 128-byte ha1 stack buffer with no upper-bound check (CWE-121), so an over-length credential string corrupts adjacent stack memory and can cause a crash or potentially code execution. No public exploit identified at time of analysis; EPSS is very low (0.04%, 13th percentile) and it is not in CISA KEV, though CISA SSVC rates technical impact as total and automatable as yes.

Stack buffer overflow in ngtcp2, a C implementation of the IETF QUIC protocol, affects all versions prior to 1.22.1 when the qlog logging callback is enabled. The function ngtcp2_qlog_parameters_set_transport_params() serializes peer-supplied QUIC transport parameters into a fixed 1024-byte stack buffer without bounds checking, so a remote peer can send oversized transport parameters during the handshake to write past the buffer and crash the process (availability impact per CVSS 7.5). SSVC lists exploitation status as 'poc' and there is publicly available exploit code exists, but EPSS is very low at 0.04% (12th percentile), and it is not in CISA KEV.
