CVE-2026-90559

snappy-java through 1.1.10.8 contains a buffer overflow vulnerability in Snappy.compress(ByteBuffer, ByteBuffer) that writes past the end of the destination buffer. Attackers can supply incompressible data that exceeds the destination buffer's remaining capacity, corrupting off-heap memory and causing JVM termination.

snappy-java through 1.1.10.8 contains a buffer overflow vulnerability in typed Snappy.uncompress*Array methods that allocate output arrays by dividing uncompressed length by element size but pass the undivided length to native code. Attackers controlling compressed input can cause misaligned length values to write past array bounds with attacker-controlled bytes, corrupting heap memory.

The snappy-java library has a flaw related to unchecked chunk length that can lead to a critical error in versions prior to 1.1.10.1. The hasNextChunk function does not validate the chunkSize variable, which can result in a NegativeArraySizeException or OutOfMemoryError.

The snappy-java library has an issue with unchecked multiplications that may lead to integer overflow in versions prior to 1.1.10.1. The `compress(char[] input)` function does not check the length of the array, which can result in critical errors.

The snappy-java library has a vulnerability related to unchecked multiplications, which may lead to integer overflow in versions prior to 1.1.10.1. The `shuffle(int[] input)` function can cause a critical error when the array length is not properly checked.
