A Use-After-Free (UAF) vulnerability exists in the EVS HAL, allowing a privileged client to free a `buffer_handle_t` while the producer thread is still using it. This race condition, triggered via `doneWithFrame` and `setMaxFramesInFlight`, enables an attacker to manipulate freed heap memory, potentially leading to the leakage of file descriptors from the EVS HAL process.

CVE-2026-1243085.8 MÉD—
——0Fraunhofer HHI VVdeC before 3.2.1 contains a heap use-after-free vulnerability in DecLibRecon::createSubPicRefBufs because decompressPicture clears m_subPicExtTasks without waiting for pending tasks. Attackers can supply a crafted multi-subpicture VVC bitstream to decoders using two or more threads, causing heap memory corruption or a decoder crash.16hCVE-2026-1243075.8 MÉD—
——0Fraunhofer HHI VVdeC before 3.2.1 contains a heap use-after-free vulnerability that allows attackers to corrupt memory by redefining an ALF adaptation parameter set id still referenced by slices. Attackers can supply a crafted VVC bitstream that, with multithreaded decoding, makes worker threads dereference freed APS objects in CABACReader::readAlf() and AdaptiveLoopFilter::reconstructCoeff(), causing crashes or heap corruption.16hCVE-2026-173377.4 ALT16.5%
——5IBM API Connect 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to bypass authentication due to improper certificate validation. A certificate check is not performed reliably in all cases, which could allow a connection to be accepted without proper authentication.1dCVE-2026-1240408.1 ALT44.1%
——13CivetWeb through 1.16, when built with USE_HTTP2 and enable_http2 on, contains a use-after-free vulnerability in handle_http2() that retains freed :method and :path pointers. Unauthenticated remote attackers can send a later HEADERS frame omitting these pseudo-headers to influence request method or path seen by access rules, or crash the server.1dCVE-2026-934247.5 ALT20.4%
——6FastNetMon is a high-performance DDoS detector and sensor. In version 1.2.9 and earlier, peer_find_template() in src/netflow_plugin/netflow_collector.cpp and src/netflow_plugin/netflow_v9_collector.cpp returns a pointer into global_netflow9_templates after releasing the cache mutex. On deployments with at least two entries in netflow_ports, concurrent template redefinition and data-flowset processing can let add_update_peer_template() reassign the template and free its records vector while another listener dereferences the escaped pointer. An unauthenticated sender that can reach both NetFlow/IPFIX listener ports can trigger a heap-use-after-free and reliably crash FastNetMon. No fixed release is available as of this review.2dCVE-2026-926945.9 MÉD16.0%
——5FastNetMon is a high-performance DDoS detector and sensor. In version 1.2.9 and earlier, FastNetMon's IPv6 top-talkers screen-draw thread in draw_table_ipv6() in src/fastnetmon_logic.cpp iterates ipv6_host_counters.average_speed_map without holding counter_map_mutex while recalculate_speed() inserts new keys and may rehash the same map. The race requires networks_list to include the targeted IPv6 range. It causes confirmed undefined behavior under load; a process crash is plausible but was not observed, so reliable denial of service has not been established. No fixed release is available as of this review.2d
