CVE-2025-22920 1 Ffmpeg 1 Ffmpeg 2026-04-15 5.3 Medium
A heap buffer overflow vulnerability in FFmpeg before commit 4bf784c allows attackers to trigger a memory corruption via supplying a crafted media file in avformat when processing tile grid group streams. This can lead to a Denial of Service (DoS).
CVE-2025-29069 2026-04-15 7.3 High
A heap buffer overflow vulnerability has been identified in the lcms2-2.16. The vulnerability exists in the UnrollChunkyBytes function in cmspack.c, which is responsible for handling color space transformations. NOTE: this is disputed by the Supplier because the finding identified a bug in a third-party calling program, not in lcms.
CVE-2025-50130 2026-04-15 7.8 High
A heap-based buffer overflow vulnerability exists in VS6Sim.exe contained in V-SFT and TELLUS provided by FUJI ELECTRIC CO., LTD. Opening V9 files or X1 files specially crafted by an attacker on the affected product may lead to arbitrary code execution.
CVE-2025-9951 1 Ffmpeg 1 Ffmpeg 2026-04-15 N/A
A heap-buffer-overflow write exists in jpeg2000dec FFmpeg which allows an attacker to potentially gain remote code execution or cause denial of service via the channel definition cdef atom of JPEG2000.
CVE-2025-7493 1 Redhat 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more 2026-04-15 9.1 Critical
A privilege escalation flaw from host to domain administrator was found in FreeIPA. This vulnerability is similar to CVE-2025-4404, where it fails to validate the uniqueness of the krbCanonicalName. While the previously released version added validations for the admin@REALM credential, FreeIPA still does not validate the root@REALM canonical name, which can also be used as the realm administrator's name. This flaw allows an attacker to perform administrative tasks over the REALM, leading to access to sensitive data and sensitive data exfiltration.
CVE-2025-3713 2026-04-15 7.5 High
The LCD KVM over IP Switch CL5708IM has a Heap-based Buffer Overflow vulnerability in firmware versions prior to v2.2.215, allowing unauthenticated remote attackers to exploit this vulnerability to perform a denial-of-service attack.
CVE-2025-3712 2026-04-15 7.5 High
The LCD KVM over IP Switch CL5708IM has a Heap-based Buffer Overflow vulnerability in firmware versions prior to v2.2.215, allowing unauthenticated remote attackers to exploit this vulnerability to perform a denial-of-service attack.
CVE-2024-10253 2026-04-15 4.7 Medium
A potential TOCTOU vulnerability was reported in PC Manager, Lenovo Browser, and Lenovo App Store that could allow a local attacker to cause a system crash.
CVE-2024-10254 2026-04-15 4.7 Medium
A potential buffer overflow vulnerability was reported in PC Manager, Lenovo Browser, and Lenovo App Store that could allow a local attacker to cause a system crash.
CVE-2025-49604 2026-04-15 5.4 Medium
For Realtek AmebaD devices, a heap-based buffer overflow was discovered in Ameba-AIoT ameba-arduino-d before version 3.1.9 and ameba-rtos-d before commit c2bfd8216a1cbc19ad2ab5f48f372ecea756d67a on 2025/07/03. In the WLAN driver defragment function, lack of validation of the size of fragmented Wi-Fi frames may lead to a heap-based buffer overflow.
CVE-2025-36853 1 Microsoft 1 .net 2026-04-15 7.5 High
A vulnerability (CVE-2025-21172) exists in msdia140.dll due to integer overflow and heap-based overflow. Per CWE-122: Heap-based Buffer Overflow, a heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().‍ Per CWE-190: Integer Overflow or Wraparound, is when a product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number. NOTE: This CVE affects only End Of Life (EOL) software components. The vendor, Microsoft, has indicated there will be no future updates nor support provided upon inquiry.
CVE-2024-21885 1 Redhat 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more 2026-04-15 7.8 High
A flaw was found in X.Org server. In the XISendDeviceHierarchyEvent function, it is possible to exceed the allocated array length when certain new device IDs are added to the xXIHierarchyInfo struct. This can trigger a heap buffer overflow condition, which may lead to an application crash or remote code execution in SSH X11 forwarding environments.
CVE-2025-48514 1 Amd 8 Epyc 7003 Series Processors, Epyc 8004 Series Processors, Epyc 9004 Series Processors and 5 more 2026-04-15 N/A
Insufficient Granularity of Access Control in SEV firmware can allow a privileged attacker to create a SEV-ES Guest to attack SNP guest, potentially resulting in a loss of confidentiality.
CVE-2025-11947 1 Bftpd 1 Bftpd 2026-04-15 4.5 Medium
A weakness has been identified in bftpd up to 6.2. Impacted is the function expand_groups of the file options.c of the component Configuration File Handler. Executing a manipulation can lead to heap-based buffer overflow. It is possible to launch the attack on the local host. Attacks of this nature are highly complex. The exploitability is considered difficult. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2025-11961 1 Tcpdump 1 Libpcap 2026-04-15 1.9 Low
pcap_ether_aton() is an auxiliary function in libpcap, it takes a string argument and returns a fixed-size allocated buffer. The string argument must be a well-formed MAC-48 address in one of the supported formats, but this requirement has been poorly documented. If an application calls the function with an argument that deviates from the expected format, the function can read data beyond the end of the provided string and write data beyond the end of the allocated buffer.
CVE-2024-6873 1 Clickhouse 1 Clickhouse 2026-04-15 8.1 High
It is possible to crash or redirect the execution flow of the ClickHouse server process from an unauthenticated vector by sending a specially crafted request to the ClickHouse server native interface. This redirection is limited to what is available within a 256-byte range of memory at the time of execution, and no known remote code execution (RCE) code has been produced or exploited.  Fixes have been merged to all currently supported version of ClickHouse. If you are maintaining your own forked version of ClickHouse or using an older version and cannot upgrade, the fix for this vulnerability can be found in this commit  https://github.com/ClickHouse/ClickHouse/pull/64024 .
CVE-2024-56827 1 Redhat 1 Enterprise Linux 2026-04-15 5.6 Medium
A flaw was found in the OpenJPEG project. A heap buffer overflow condition may be triggered when certain options are specified while using the opj_decompress utility. This can lead to an application crash or other undefined behavior.
