Security vulnerability affects the zstd package. Beginning in v1...

Uncontrolled Resource Consumption

zstd-jni is vulnerable to Uncontrolled Resource Consumption. The vulnerability is due to improper validation of negative length parameters in ZstdInputStreamNoFinalizer.read, which allows an attacker to trigger an infinite loop that holds the stream monitor and blocks other threads from accessing...

Out-of-Bounds Read

zstd-jni is vulnerable to Out-of-Bounds Read. The vulnerability is due to improper validation of negative srcPosition arguments in Zstd.getFrameContentSize, which allows an attacker to bypass bounds checks and trigger out-of-bounds memory reads, potentially causing information disclosure or JVM...

Out-Of-Bounds Read

zstd-jni is vulnerable to an out-of-bounds read. The vulnerability is due to the ZstdDictDecompress constructor not validating the offset and length arguments against the dictionary array bounds, which allows an attacker to provide arbitrary values to read memory beyond the supplied array and...

CVE-2026-98079

The Linux kernel contains a concurrency issue in the btrfs: zstd component where a writer can sleep indefinitely in zstd_get_workspace(). The root cause is a lost wakeup occurring because zstd_alloc_workspace() fails and the task queues unconditionally on zwsm->wait without re-testing the pool...
