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...

PT-2026-98742

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A race condition exists in the btrfs zstd implementation where a writer may sleep indefinitely in the zstd get workspace function despite a workspace being available. This occurs because...

com.github.luben/zstd-jni: zstd-jni: Use-After-Free vulnerability allows memory corruption and denial of service

A flaw was found in zstd-jni. An attacker could exploit a use-after-free vulnerability by calling specific methods on closed streams without proper validation. This could lead to memory corruption, potentially allowing the attacker to corrupt unrelated objects or cause the Java Virtual Machine JV...

com.github.luben/zstd-jni: luben zstd-jni: Remote use-after-free vulnerability in dictionary sharing

A flaw was found in luben zstd-jni. This flaw involves a use-after-free vulnerability in the ZstdCompressCtx.loadDict function, which handles dictionary sharing. A remote attacker could exploit this by manipulating dictionary sharing operations, potentially leading to denial of service, informati...

com.github.luben/zstd-jni: zstd-jni: Denial of Service (DoS) via out-of-bounds read in Zstd.trainFromBufferDirect

A flaw was found in zstd-jni. Attackers can exploit this by supplying oversized per-sample lengths to the Zstd.trainFromBufferDirect function, which fails to validate the samples buffer capacity. This allows for reading past buffer boundaries, leading to out-of-bounds memory access and ultimately...

zstd-jni: zstd-jni: Information disclosure or denial of service via out-of-bounds read

A flaw was found in zstd-jni. This out-of-bounds read vulnerability in the Zstd.getFrameContentSize function occurs because it fails to validate negative srcPosition arguments. A remote attacker can supply negative offset values, bypassing bounds checks and accessing the native frame-header parse...

com.github.luben/zstd-jni: zstd-jni: Denial of Service via out-of-bounds read in ZstdDictDecompress

A flaw was found in zstd-jni. This vulnerability, an out-of-bounds read, occurs in the ZstdDictDecompress constructor due to insufficient validation of offset and length arguments against dictionary array bounds. A remote attacker could exploit this by providing specially crafted input, leading t...

com.github.luben/zstd-jni: zstd-jni: Out-of-bounds read in ZstdDictCompress constructor leads to denial of service

A flaw was found in zstd-jni. This vulnerability occurs due to insufficient validation of offset and length parameters within the ZstdDictCompress constructor. An attacker can exploit this by providing untrusted values, leading to an out-of-bounds memory read. This can result in the disclosure of...

com.github.luben/zstd-jni: zstd-jni: Data corruption or denial of service via use-after-free vulnerability

A flaw was found in zstd-jni. This use-after-free vulnerability occurs because streams and contexts only hold a dictionary's shared lock during the load call, allowing the dictionary to be closed while still being referenced. A remote attacker could exploit this by closing a dictionary after...

Linux Kernel Security Vulnerabilities

The Linux kernel has a security vulnerability. This vulnerability stems from btrfs zstd failing to wake up while waiting for the work area. When zstdallocworkspace fails, tasks wait in queue without being rechecked in the pool. As a result, when the work area is idle, writers may remain permanent...
