Summary An attacker can cause excessive memory allocation in quic-go's HTTP/3 client and server implementations by sending a QPACK-encoded HEADERS frame that decodes into a large trailer field section with many unique field names and/or large values. The implementation builds an http.Header for t...
CVE-2026-9759
A flaw was found in the ROHC dissector in Wireshark. This issue occurs when malformed packets are decoded from a pcap file or the network, causing a NULL pointer dereference, resulting in a denial of service. Mitigation If the ROHC protocol dissector is not being used, it can be disabled via the...

SUSE CVE-2026-45843
In the Linux kernel, the following vulnerability has been resolved: slip: bound decode reads against the compressed packet length slhcuncompress parses a VJ-compressed TCP header by advancing a pointer through the packet via decode and pull16. Neither helper bounds-checks against isize, and decod...

Wireshark is a set of network packet analysis tools developed by the Wireshark team. The software’s function is to capture network packets and display detailed data for analysis. Versions of Wireshark from 4.6.0 to 4.6.5, as well as 4.4.0 to 4.4.15, have code vulnerabilities that can lead to a...
Astra Linux - уязвимость в nghttp2
nghttp2 is an implementation of the Hypertext Transfer Protocol Version 2 in C. The nghttp2 library prior to version 1.61.0 continued to read an unlimited number of HTTP/2 CONTINUATION frames even after a stream was reset, in order to keep the HPACK context synchronized. This caused excessive CPU...
CVE-2026-43970
Improper Handling of Highly Compressed Data Data Amplification vulnerability in ninenines cowlib allows unauthenticated remote denial of service via memory exhaustion. cowspdy:inflate/2 in cowlib passes peer-supplied compressed bytes directly to zlib:inflate/2 with no output size bound. The SPDY...
Denial Of Service (DoS)
Node.js is vulnerable to Denial of Service DoS. The vulnerability is due to improper handling of malformed HTTP/2 HEADERS frames containing invalid HPACK data, which can trigger an unhandled TLSSocket ECONNRESET error and cause the Node.js process to crash, enabling remote denial of service...
