Integer overflow in Klever-Go's semi-fungible token (SFT) add-quantity path prior to version 1.7.19 allows a mint-role holder to bypass a finite per-nonce MaxSupply constraint, minting approximately 9.2×10^18 tokens in a single transaction. The SFTAddCirculation function in core/kapp/systemAccount/systemAcount.go increments Circulation before checking the cap, enabling an int64 wraparound that makes the MaxSupply comparison permanently false. A proof-of-concept unit test is included in GHSA-mrpp-v6pg-p54x confirming the bypass; no CISA KEV listing is present at time of analysis.
Unbounded native-token (KLV) minting in the Klever blockchain node (klever-go < 1.7.19) lets any funded account inflate the ledger at will. Split-royalty percentages on a KDA asset are validated by summing per-entry values into a uint32 accumulator with no per-entry cap, so two entries near 0x80000000 wrap the sum below the 10000 (100%) limit and pass validation while each stored percentage stays astronomically large; at payout every split recipient is credited pool × hugePct / 10000 and the negative remainder is silently dropped, minting KLV out of thin air. A full working proof-of-concept is published in the GitHub Security Advisory (GHSA-cgc5-v3f2-8m2v); it is not in CISA KEV and no EPSS score was provided, but the flaw is exploitable on current mainnet and not gated by any fork flag.
Integer overflow in FFmpeg's libswscale/utils.c component, present in development snapshot N-122528-gdd2976b9e1, allows unauthenticated remote attackers to crash any application relying on that component for image scaling by supplying a specially crafted image file. The CVSS 7.5 High rating reflects a network-reachable, zero-authentication denial-of-service path, but the EPSS score of 0.15% at the 4th percentile indicates negligible observed exploitation activity. No public exploit code and no CISA KEV listing are confirmed at time of analysis.
Integer overflow in FFmpeg's libswscale/output.c (yuv2planeX_8_c function) allows a remote attacker to crash the FFmpeg process by supplying a crafted video file, causing denial of service in any pipeline that processes untrusted media. The affected build is development snapshot N-122528-gdd2976b9e1; stable release exposure is unconfirmed. No public exploit code and no CISA KEV listing exist; EPSS of 0.15% (4th percentile) indicates very low near-term exploitation probability despite the high CVSS base score.
Integer overflow in FFmpeg's libswscale image-scaling library (output.c) enables Denial of Service against any service or application that processes attacker-supplied media through the swscale API. The flaw, confirmed in snapshot build N-122528-gdd2976b9e1, resides in the target_sws_fuzzer() harness and indicates that the underlying scaling output path contains an integer wraparound reachable via crafted input. No active exploitation is confirmed (not in CISA KEV), no public exploit code has been identified, and EPSS probability is negligible at 0.15%, suggesting minimal current threat actor interest.
Integer overflow in Open5GS v2.7.6's Session Management Function (SMF) allows remote unauthenticated attackers to crash the service via a crafted GTP packet, causing Denial of Service against 5G core network infrastructure. The CVSS vector (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) confirms zero-authentication network exploitation requiring no user interaction. Researcher-published proof-of-concept code exists in a public GitHub repository and gist, though no CISA KEV listing confirms active in-the-wild exploitation at time of analysis.
Integer overflow in FFmpeg's libswscale library allows any application or service processing attacker-controlled image files to be crashed via a specially crafted input, causing a Denial of Service. The vulnerable function hScale16To19_c() in output.c is affected in build N-122528-gdd2976b9e1; the CVSS vector (AV:N/AC:L/PR:N/UI:N) reflects worst-case exposure in automated media-processing services. Despite the high CVSS score of 7.5, the EPSS probability is just 0.15% at the 4th percentile and no active exploitation has been confirmed, indicating limited real-world exploitation activity at time of analysis.
Denial of Service in Spring Reactor Core affects any JVM service that uses the Flux.windowTimeout operator with the fairBackpressure option enabled, across three major release trains (3.4.x through 3.8.6). An unauthenticated network attacker can trigger resource exhaustion or stall the reactive pipeline, causing full availability loss for the affected service. No active exploitation is confirmed (not listed in CISA KEV) and no public exploit code has been identified at time of analysis; the high attack complexity rating (AC:H) reflects the requirement for a specific, non-default operator configuration.
Stack-based denial of service in GIMP's Seattle FilmWorks (SFW) image plugin crashes the application when a crafted SFW file triggers an unbounded variable-length array allocation on the stack. The flaw affects all GIMP versions per the GNOME CPE string and is confirmed across Red Hat Enterprise Linux 6 through 9. An attacker who can deliver a malicious SFW file to a user can reliably crash the GIMP process with no code execution or data exposure; no public exploit has been identified at time of analysis.
CorvusSKK, a Windows-based SKK Japanese input method editor by Sasaki Nobuyuki, contains a signed 32-bit integer overflow (CWE-190) in its tar-format dictionary file size parsing, which can allow malicious data to be written to a dictionary file when a user opens a crafted input. All versions prior to 3.3.4 are affected; version 3.3.4 was released to address this flaw alongside a separate Lua-related vulnerability. No public exploit has been identified at time of analysis and the vulnerability is not listed in the CISA KEV catalog, indicating no confirmed active exploitation.
