CVE-2026-80982

CVE-2026-80982 is a use-after-free in the Linux kernel's SMC (Shared Memory Communications) network protocol (net/smc). The root cause is a race condition in smc_rx_pipe_buf_release(): it checks sk_state before acquiring the socket lock, so a concurrent smc_conn_free() can release the connection ...

CVE-2026-87776 compression vulnerable to Denial of Service via memory leak on premature response close

compression is a Node.js and Express compression middleware. In versions before 1.8.2, when a client aborts the connection while a compressed response is still being sent, the zlib stream created to compress that response is never destroyed, so each aborted compressed response leaks its native zl...

CVE-2026-87776

compression is a Node.js and Express compression middleware. In versions before 1.8.2 , when a client aborts a connection while a compressed response is still being sent, the associated zlib stream is never destroyed, causing native zlib memory to leak with each aborted response. A remote unauthe...

ws: ws: Uninitialized memory disclosure via `websocket.close()` with `TypedArray`

A flaw was found in ws, an open source WebSocket client and server for Node.js. The websocket.close implementation is vulnerable to uninitialized memory disclosure when a TypedArray is passed as the reason argument. This can lead to the disclosure of sensitive information from uninitialized memor...

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...
