CVE-2026-1168426.1 MED—
———DevilutionX 1.4.0 through 1.5.5 contains a heap buffer overflow vulnerability in the bundled libmpq libmpq__archive_dup routine when opening crafted MPQ archives. Attackers can supply an MPQ archive whose block table count exceeds its hash table count, causing memcpy to overflow the heap during startup and crash the game.7hCVE-2026-1167416.5 MED—
———Speex (libspeex) through 1.2.1 contains an out-of-bounds write vulnerability in speex_bits_read_whole_bytes() in libspeex/bits.c that mishandles length truncation for non-owned SpeexBits buffers. Attackers can stream crafted Speex data into buffers set up with speex_bits_init_buffer() or speex_bits_set_bit_buffer() to corrupt heap or stack memory and crash applications.10hCVE-2026-1165905.9 MED—
———snappy-java is a Java port of the snappy, a fast C++ compresser/decompresser developed by Google. Prior to 1.1.10.9, Snappy.arrayCopy(Object src, int offset, int byteLength, Object dest, int destOffset) passes caller-supplied ranges to native memcpy without validating either array, allowing negative or oversized byteLength and offset values to read or write outside array bounds and crash the JVM. SnappyOutputStream.rawWrite and SnappyInputStream.rawRead, including their typed-array write and read methods, pass caller-controlled ranges through this primitive, and typed-array byte-size calculations can overflow int. This issue is fixed in version 1.1.10.9.10hCVE-2026-869716.5 MED—
———An out-of-bounds write issue was addressed with improved bounds checking. This issue is fixed in iOS 26.7.2 and iPadOS 26.7.2, iOS 27.2 and iPadOS 27.2, macOS Golden Gate 27.2, macOS Sequoia 15.8.2, macOS Tahoe 26.7.2, visionOS 27.2. Processing a maliciously crafted image may lead to unexpected app termination.7hCVE-2026-844966.5 MED—
———An out-of-bounds write issue was addressed with improved bounds checking. This issue is fixed in macOS Golden Gate 27.2, macOS Tahoe 26.7.2. Mounting a maliciously crafted disk image may cause unexpected system termination or corrupt kernel memory.7hCVE-2026-1165024.4 MED—
———A flaw has been found in turboderp-org ExLlamaV2 up to 0.3.2. The impacted element is the function QMatrix::make_sequential of the file exllamav2/exllamav2_ext/cuda/q_matrix.cu of the component GPTQ Index Handler. Executing a manipulation of the argument g_idx can lead to out-of-bounds write. The attack needs to be launched locally. The project was informed of the problem early through an issue report but has not responded yet.11h
