OpenSSH Compression Payload Size Vulnerability (CVE-2026-110927)

Sources read

1

Source agreement

Tam uyum

Evidence confidence

%55

Short explanation

A flaw exists in OpenSSH where a compressed payload can expand past the maximum supported packet size after compression is negotiated. Because the inflate loop does not stop at that limit, memory usage grows in the process handling that connection.

Why does it matter?

This vulnerability allows attackers to increase memory consumption, potentially jeopardizing service availability. It can lead to performance degradation or service disruptions on affected systems.

What should be done?

  • Follow vendor security advisories
  • Review official announcements for available patches
Chain of evidence and sources2 verified claims

OpenSSH içinde sıkıştırma müzakeresi sonrasında sıkıştırılmış yük maksimum desteklenen paket boyutunu aşabilmektedir.

Şişirme döngüsü sınırda durmadığı için bağlantıyı işleyen süreçte bellek kullanımı artmaktadır.
