CVE-2026-106585

A flaw was found in OpenSSH. A remote attacker can trigger a denial of service DoS or abnormal packet processing by transmitting crafted, highly compressed data to a vulnerable client or server. The application fails to verify that decompressed payloads remain within the maximum permitted packet...

Astra Linux – Vulnerability in Qemu

In QEMU versions up to 5.0.0, an assertion failure can occur during network packet processing. This issue affects the e1000e and vmxnet3 network devices. A malicious guest user/process could exploit this flaw to terminate the QEMU process on the host, resulting in a denial-of-service condition in...

UBUNTU-CVE-2026-100236

A flaw was found in the DPDK GSO library. When software GSO copies packet headers into a new mbuf, it does not check that the header fits in the source first segment or in the destination buffer, and a header longer than the configured GSO segment size can underflow the payload-size calculation. ...
