CWE-758
Reliance on Undefined, Unspecified, or Implementation-Defined Behavior
Monthly
Incorrect interface method dispatch in Eclipse OpenJ9 up to version 0.60 causes the JVM to silently execute an unintended interface default method instead of raising AbstractMethodError or IllegalAccessError when a previously JIT-compiled concrete superclass method is subsequently recompiled as abstract. Applications running on OpenJ9 with dynamic class-loading or OSGi-style hot deployment are at risk of integrity violations - untended code paths execute where exceptions should be thrown. No confirmed active exploitation exists and this CVE does not appear in CISA KEV; EPSS data was not provided, and the high attack complexity (AC:H) and specific attack prerequisites (AT:P) significantly limit real-world exploitability.
Incorrect conditional-move output in the RustCrypto `cmov` crate's aarch64 backend causes cryptographic constant-time operations to silently produce wrong results on aarch64 platforms. The inline assembly implementations of `Cmov` and `CmovEq` compare full 32-bit register contents instead of the intended narrowed type widths when evaluating conditions, because Rust's inline assembly specification explicitly leaves upper register bits undefined for inputs smaller than the register size. A proof-of-concept demonstrating the failure is included in the advisory; the vulnerability is not listed in CISA KEV and no active exploitation has been reported.
Ghidra before 11.2 contains a use after free vulnerability in the Sleigh backend caused by undefined static initialization order of the SleighArchitecture::translators and XmlArchitectureCapability. Rated low severity (CVSS 2.1), this vulnerability is no authentication required, low attack complexity.
BACnet Stack prior to version 1.4.3 exhibits undefined behavior in the decode_signed32() function when processing signed-integer property values containing bytes with the high bit set, causing denial of service through integer overflow. Network-remote attackers can trigger this vulnerability by sending specially crafted BACnet packets with high-bit-set byte sequences, resulting in application instability or crash on embedded systems running vulnerable versions. The vulnerability is confirmed fixed in version 1.4.3.
Local denial of service in iccDEV prior to version 2.3.1.6 allows unauthenticated local attackers to crash applications processing ICC color profiles by crafting malicious profiles that trigger undefined behavior through invalid enum values in CIccOpDefEnvVar::Exec(). The vulnerability requires local file access but no privilege escalation, with an EPSS score of 6.2 reflecting moderate real-world risk. No public exploit code or active exploitation has been identified at the time of analysis.
Undefined Behavior in iccDEV prior to version 2.3.1.6 allows local attackers to cause a denial of service by supplying a crafted ICC color profile containing invalid enum values for icChannelFuncSignature, which triggers an application crash during profile processing in CIccCalculatorFunc::ApplySequence(). The vulnerability requires local file access or the ability to provide a malicious ICC profile to an application using the library; no public exploit code has been identified.
Denial of service via crafted ICC color profile in iccDEV library prior to version 2.3.1.6 triggers undefined behavior through invalid left shift operations on 32-bit unsigned integers, causing application crashes. The vulnerability affects all iccDEV versions before 2.3.1.6 and requires only local file access to exploit (no authentication or user interaction required beyond opening a malicious profile). No public exploit code or active exploitation has been identified at time of analysis.
Denial of service via undefined behavior in iccDEV versions prior to 2.3.1.6 allows local attackers to crash the iccDumpProfile tool by supplying a crafted ICC color profile. The vulnerability exploits an unsafe memory operation in IccUtil.cpp triggered during profile parsing, resulting in application termination with no authentication required. No public exploit code or active exploitation has been reported at time of analysis.
An undefined behavior vulnerability exists in the WebRTC Signaling component of Mozilla Firefox and Firefox ESR, potentially leading to information disclosure. This affects Firefox versions below 149 and Firefox ESR versions below 140.9. An attacker can exploit this through WebRTC signaling interactions to disclose sensitive information, though specific exploitation details remain limited in public disclosures.
An undefined behavior vulnerability exists in the WebRTC Signaling component of Mozilla Firefox and Firefox ESR, potentially enabling information disclosure attacks. Firefox versions prior to 149 and Firefox ESR versions prior to 140.9 are affected. While specific exploitation mechanics are not fully detailed in available public sources, the vulnerability is classified as an information disclosure issue that could allow attackers to extract sensitive data through malformed WebRTC signaling messages.
