CVE-2026-53132

A flaw was found in the Linux kernel's vsock/virtio component. A remote attacker could send specially crafted packets with zero length and an End-of-Message EOM flag. This could lead to an unbounded queue of packets, consuming excessive memory and potentially causing a Denial of Service DoS due t...

CVE-2026-53132

CVE-2026-53132 affects the Linux kernel vsock/virtio, where receiving zero-length packets with VIRTIO_VSOCK_SEQ_EOM could cause an unbounded skb queue growth, exhausting memory. The root cause is a miscalculation of backlog: vvs->rx_bytes + len > vvs->buf_alloc allows large queues when l...

OESA-2023-1312 c-ares security update

This is c-ares, an asynchronous resolver library. It is intended for applications which need to perform DNS queries without blocking, or need to perform multiple Security Fixes: c-ares is an asynchronous resolver library. c-ares is vulnerable to denial of service. If a target resolver sends a...

AZL-26942 CVE-2023-32067 affecting package python-gevent for versions less than 21.1.2-3

c-ares is an asynchronous resolver library. c-ares is vulnerable to denial of service. If a target resolver sends a query, the attacker forges a malformed UDP packet with a length of 0 and returns them to the target resolver. The target resolver erroneously interprets the 0 length as a graceful...

c-ares is an asynchronous resolver library. c-ares is vulnerable to denial of service. If a target resolver sends a query, the attacker forges a malformed UDP packet with a length of 0 and returns them to the target resolver. The target resolver erroneously interprets the 0 length as a graceful...

Bro Buffer Overflow Vulnerability

Bro is an open source framework for network analysis and security monitoring . A security vulnerability exists in the analyzer/protocol/dnp3/DNP3.cc file in Bro versions prior to 2.3.2, which stems from the program failing to properly handle packets of zero length. A remote attacker could exploit...

kernel: firewire: ohci: handle receive packets with a data length of zero

drivers/firewire/ohci.c in the Linux kernel before 2.6.32-git9, when packet-per-buffer mode is used, allows local users to cause a denial of service NULL pointer dereference and system crash or possibly have unknown other impact via an unspecified ioctl associated with receiving an ISO packet tha...
