OpenSlide: openslide_read_region() returns uninitialized memory with libtiff 4.7.1
OpenSlide is a C library for reading whole slide image files. Prior to 4.0.1, a behavior change in libtiff 4.7.1 causes the indirect TIFF tile path in src/openslide-decode-tiff.c and _openslide_tiff_read_tile() to request a full-height destination for a partial bottom tile row, allowing uninitialized heap memory to enter pixel data returned by openslide_read_region(). A crafted but valid slide can trigger the issue in TIFF-based formats other than Hamamatsu NDPI when a network service renders attacker-provided slides. Successful extraction depends on pixel transparency handling and recompression, OpenSlide with libtiff 4.7.0 or earlier is not affected, and official binary builds 4.0.0.10 and 4.0.0.11 are affected. This issue is fixed in OpenSlide 4.0.1 and official binary build 4.0.0.12.

Eclipse OpenJ9 : Method resolution default method precedence failure
In Eclipse OpenJ9 versions up to 0.60, when executing class files where a previously concrete superclass method has been recompiled as abstract, execution is incorrectly delegated to an interface default method.

CWE-758 17/07/2026
RustCrypto Cmov/CmovEq on aarch64 can produce wrong results if high-bits of registers are set
RustCrypto CMOV provides conditional move CPU intrinsics which are guaranteed on major platforms to execute in constant-time and not be rewritten as branches by the compiler. From 0.1.1 until 0.5.4, the aarch64 implementations of Cmov and CmovEq in cmov/src/backends/aarch64.rs assume high bits are zero-extended when loading values smaller than a register, so set high bits such as [8..] in a Cmov selector or [16..] of self or other in the u16 and i16 CmovEq implementations can cause left.cmovz(&right, condition) to produce incorrect output. This issue is fixed in version 0.5.4.

CWE-758 10/06/2026
Ghidra < 11.2 - Use After Free in Sleigh Backend via Static Initialization Order
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 singletons. Attackers can trigger an infinite loop or denial of service during shutdown by exploiting the unsafe destruction order that causes iteration over deallocated memory.

CWE-758 21/04/2026
BACnet Stack: Undefined-behavior signed left shift in `decode_signed32()`
BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to 1.4.3, decode_signed32() in src/bacnet/bacint.c reconstructs a 32-bit signed integer from four APDU bytes using signed left shifts. When any of the four bytes has bit 7 set (value ≥ 0x80), the left-shift operation overflows a signed int32_t, which is undefined behavior per the C standard. This is flagged thousands of times per minute by UndefinedBehaviorSanitizer on any BACnet input containing signed-integer property values with high-bit-set bytes. This vulnerability is fixed in 1.4.3.

CWE-758 31/03/2026
iccDEV: UB at IccUtil.cpp
iccDEV provides a set of libraries and tools for working with ICC color management profiles. Prior to version 2.3.1.6, there is an Undefined Behavior (UB) condition in IccUtil.cpp triggered by a crafted input profile. Under UndefinedBehaviorSanitizer, the issue is reported as invalid left shift operations on icUInt32Number (unsigned 32-bit) where the shifted value “cannot be represented” in that type. This issue has been patched in version 2.3.1.6.

CWE-758 31/03/2026
iccDEV: UB at IccUtil.cpp
iccDEV provides a set of libraries and tools for working with ICC color management profiles. Prior to version 2.3.1.6, an Undefined Behavior (UB) condition in IccUtil.cpp can be triggered by a crafted ICC profile when running iccDumpProfile. This issue has been patched in version 2.3.1.6.

CWE-758 31/03/2026
iccDEV: UB in CIccOpDefEnvVar::Exec()
iccDEV provides a set of libraries and tools for working with ICC color management profiles. Prior to version 2.3.1.6, a crafted ICC profile can trigger Undefined Behavior (UB) in CIccOpDefEnvVar::Exec() due to invalid enum values being loaded for icSigCmmEnvVar. The issue is observable under UBSan as a “load of value … not a valid value for type icSigCmmEnvVar”, indicating an invalid enum/type value being consumed during ICC profile processing. This issue has been patched in version 2.3.1.6.

CWE-758 31/03/2026
iccDEV: UB in CIccCalculatorFunc::ApplySequence()
iccDEV provides a set of libraries and tools for working with ICC color management profiles. Prior to version 2.3.1.6, a crafted ICC profile can trigger Undefined Behavior (UB) in CIccCalculatorFunc::ApplySequence() due to invalid enum values being loaded for icChannelFuncSignature. The issue is observable under UBSan as a “load of value … not a valid value for type icChannelFuncSignature”, indicating a type/enum value confusion scenario during ICC profile processing. This issue has been patched in version 2.3.1.6.
