CVE-2026-64290

CVE-2026-64290 affects the Linux kernel via iommufd_fault_fops_read(): on a copy_to_user() failure inside the inner loop, only the inner loop breaks, causing the outer loop to retry indefinitely and spin the reader with fault->mutex held. The public fixes implement breaking the outer while by ...

libp2p: yamux connection DoS via oversized data frame

Summary The yamux stream multiplexer in py-libp2p does not validate incoming DATA frame lengths against the receive window before reading the frame body. Any peer that completes a standard libp2p handshake can send a single 12-byte frame claiming a 4 GB body, causing the victim's yamux read loop ...

Improper Validation of Specified Quantity in Input

Overview libp2p is a libp2p: The Python implementation of the libp2p networking stack Affected versions of this package are vulnerable to Improper Validation of Specified Quantity in Input through the handleincoming process. An attacker can cause the read loop to block indefinitely by sending a...

golang.org/x/crypto/ssh: golang.org/x/crypto/ssh: Denial of Service via resource leak from unsolicited SSH responses

A flaw was found in golang.org/x/crypto/ssh. A remote malicious SSH peer can exploit this by sending unsolicited global request responses, which fills an internal buffer and blocks the connection's read loop. This prevents the associated resources from being released, leading to a resource leak p...

golang.org/x/crypto/ssh: Invoking client can cause server deadlock on unexpected responses...

Important: runfinch-finch

Issue Overview: An authenticated SSH client that repeatedly opened channels which were rejected by the server caused unbounded memory growth, eventually crashing the server process and affecting all connected users. Rejected channels are now properly removed from the connection's internal state a...
