Use After Free

Overview Affected versions of this package are vulnerable to Use After Free in the setDict, setLongMax, setLevel, and setRefMultipleDDicts methods of its streaming classes. An attacker can corrupt native heap state or crash the JVM by calling these setters on a stream after close, causing them to...

EUVD-2026-75088

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: fix use-after-free of listener socket in isoconnready isoconnready looks up the BIS listener socket with isogetsock, which takes a reference, and then, without re-checking its state, creates a child socket from it...

CVE-2026-80914

CVE-2026-80914 is a use-after-free vulnerability in the Linux kernel's Bluetooth ISO subsystem , specifically in the iso_conn_ready() function. When a BIS listener socket is closed concurrently between iso_get_sock() and lock_sock(), the socket may be freed while a child socket remains linked to ...

CVE-2026-87825

zstd-jni before 1.5.7-14 contains a use-after-free vulnerability where streams and contexts hold a dictionary's shared lock only during the load call, allowing the dictionary to be closed while still referenced. Attackers can close a dictionary after associating it with a stream or context, causi...

CVE-2026-87877 zstd-jni 1.3.8-4 through 1.5.7-13 Use-After-Free via Setters Called After close()

zstd-jni versions before 1.5.7-14 fail to validate closed state in setDict, setLongMax, setLevel and setRefMultipleDDicts methods of stream classes. Attackers can call these methods on closed streams to write through freed native pointers, corrupting unrelated objects or crashing the JVM...

undici: undici: Denial of Service via WebSocketStream unclean close

A flaw was found in undici's experimental WebSocketStream client. A remote attacker, operating as an untrusted server, can trigger a Denial of Service DoS by closing the TCP connection without a proper WebSocket close handshake. This action causes an unhandled error in the client, leading to the...
