CVE-2026-93962 1 Kamailio 1 Kamailio 2026-09-22 8.3 High
A weakness has been identified in Kamailio up to 5.8.8/6.0.7/6.1.4/6.2.0-dev1. The impacted element is the function shm_malloc of the file src/modules/cdp/receiver.c of the component CDP Diameter Receiver. Executing a manipulation can lead to heap-based buffer overflow. It is possible to launch the attack remotely. The exploit has been made available to the public and could be used for attacks. Upgrading to version 6.0.8 is sufficient to resolve this issue. This patch is called 38711a3e788de0130d48cb485578c482b57d9351/4f62235b6f477b649c5cc18b0c81b4e26c949b98/4f62235b6f477b649c5cc18b0c81b4e26c949b98. You should upgrade the affected component.

CVE-2026-69720 1 Microsoft 6 Windows 11 24h2, Windows 11 24h2, Windows 11 25h2 and 3 more 2026-09-22 7.8 High
Heap-based buffer overflow in Windows MIDI Service Module allows an authorized attacker to elevate privileges locally.
CVE-2026-55556 1 Rsyslog 1 Rsyslog 2026-09-22 7.5 High
Rsyslog is a rocket-fast system for log processing. From 8.2110.0 until 8.2604.0, the optional imhttp module's parse_auth_header function in contrib/imhttp/imhttp.c allocates a zero-byte heap buffer with calloc(0, len) when an HTTP Basic Authorization value exceeds its fixed work buffer, then passes that pointer to apr_base64_decode. An unauthenticated remote attacker can send an oversized encoded credential to an imhttp endpoint configured for Basic Authentication, causing decoded data to overwrite adjacent heap memory before credential validation. Deployments that do not install, load, and use imhttp with Basic Authentication are not affected. The demonstrated impact is a process crash that interrupts log collection, and code execution has not been demonstrated. This issue is fixed in version 8.2604.0.
CVE-2026-69685 1 Microsoft 26 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 23 more 2026-09-22 7.8 High

Heap-based buffer overflow in Windows Encrypting File System (EFS) allows an authorized attacker to elevate privileges over a network.
CVE-2026-69691 1 Microsoft 26 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 23 more 2026-09-22 7.8 High
Heap-based buffer overflow in Windows Spaceport.sys allows an authorized attacker to elevate privileges locally.
CVE-2026-75883 1 Ppp Project 1 Ppp 2026-09-22 6.8 Medium
The code in pppd that formats a response to a PEAP Request packet in peap_response() copies an entire TLS record of up to 16384 bytes into the fixed global buffer outpacket_buf without checking the available space and without implementing outgoing PEAP fragmentation. Thus a pppd process connecting to a server which requests PEAP authentication can be induced to corrupt global static data following the outpacket_buf array, most likely causing incorrect behavior or a crash.
CVE-2026-72946 1 Microsoft 8 Windows 11 24h2, Windows 11 24h2, Windows 11 25h2 and 5 more 2026-09-22 7.8 High

CVE-2026-72940 1 Microsoft 11 Windows 11 23h2, Windows 11 23h2, Windows 11 24h2 and 8 more 2026-09-22 8.8 High

CVE-2026-15028 1 Redhat 3 Enterprise Linux, Hummingbird, Openshift 2026-09-21 3.9 Low
A flaw was found in libarchive. This vulnerability allows a remote attacker to trigger a heap overflow by providing a specially crafted tar archive. The issue occurs during the parsing of a PAX extended header containing a malformed SUN.holesdata sparse-file attribute. Successful exploitation could lead to a denial of service, making the system unavailable, or potentially allow for arbitrary code execution, giving the attacker control over the affected system.
CVE-2026-77396 1 Pjsip 1 Pjproject 2026-09-21 N/A
PJSIP is a free and open source multimedia communication library written in C. In 2.17 and earlier, the PJSIP AVI parser in pjmedia/src/pjmedia/avi_player.c uses an input-file video chunk length as the number of bytes copied into a frame buffer whose capacity is derived from the declared media dimensions. A crafted AVI file can therefore cause an attacker-controlled out-of-bounds write past the heap allocation when an application plays the file or pulls its frames. The existing size assertion does not protect production release builds, where assertions are disabled. Typical local playback can crash the process, while applications that accept untrusted AVI sources expose a stronger memory-corruption condition. No fixed version is available as of this review.
CVE-2026-58264 1 Fluidsynth 1 Fluidsynth 2026-09-21 9.8 Critical
FluidSynth is a software synthesizer based on the SoundFont 2 specifications. From 1.1.2 until 2.5.6, the FluidSynth command handler accepts a pitch_bend_range command whose channel argument is not bounds checked before the supplied value is written through the selected synth channel. An out-of-range channel can therefore cause an out-of-bounds heap write, leading to denial of service or possible code execution. The issue is remotely reachable when the TCP server is enabled through new_fluid_server() or fluidsynth -s, and it is locally reachable through malicious commands delivered to the FluidSynth shell on standard input. Applications that do not use the shell, command handler, or TCP server are not affected. This issue is fixed in version 2.5.6.
CVE-2026-44236 1 Alanxz 1 Rabbitmq-c 2026-09-21 7.1 High
rabbitmq-c is a C-language AMQP client library for RabbitMQ. Prior to 0.16.0, a malicious AMQP server can send an undersized connection.tune.frame_max value during amqp_login(), and rabbitmq-c accepts the value in amqp_login_inner() in librabbitmq/amqp_socket.c. amqp_tune_connection() in librabbitmq/amqp_connection.c uses frame_max to reallocate the outbound buffer without enforcing AMQP_FRAME_MIN_SIZE. Immediate serialization of connection.tune-ok through amqp_frame_to_bytes() writes beyond the undersized heap allocation, causing memory corruption and likely denial of service. An on-path attacker can also trigger the flaw against plaintext AMQP traffic. Code execution is theoretically possible but was not demonstrated. This issue is fixed in version 0.16.0.
