Hackney has unbounded buffer accumulation in WebSocket

Summary The WebSocket client in src/hackneyws.erl imposes no upper bound on memory consumption across three distinct code paths. In each case, an attacker-controlled WebSocket server can exhaust the connecting process's memory without any authentication or special client configuration. Details 1...

EUVD-2026-39599

A flaw was found in KubeVirt's downward metrics virtio-serial server. The server reads guest requests using textproto.Reader.ReadLine, which buffers input indefinitely until a newline character is received, with no length limit or read deadline. A user with access to a VM guest that has the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: greybus: gb-beagleplay: bound bootloader receive buffering The function cc1352bootloaderrx appends each serdev chunk into the rxbuffer before parsing bootloader packets. This helper function can retain leftover bytes between...

python-multipart: Negative Content-Length in parse_form buffers the entire body in memory

Summary parseform did not validate the Content-Length header before using it to bound its chunked read of the request body. A negative Content-Length turned the bounded read into a read-until-EOF, so the entire body was loaded into memory in a single read instead of in fixed-size chunks. Details...

SUSE CVE-2026-53702
