Description

In the Linux kernel, the following vulnerability has been resolved: ipv4: validate checksum_start before completing checksum If a packet with bad checksum metadata gets into the ipv4 stack, skb_checksum_help can corrupt the network header and cause a bunch of mischief. This was discovered and reported by Paulos, and has been reporoduced by others independently since. We really shouldn't allow such packets in, but as a defence in depth measure, let's also check before we complete the checksum. A more complete validation at input is forthcoming, but needs more work.

15 октября появилась публичная информация о KVM escape и патчи ядра Linux. Авторы не предоставили публичный PoC опасаясь эксплуатации в дикой природе

А уже 17 октября был взломан FirstVDS.

Но с CVE-2026-99999 это не связано. У firstvds взлом произошёл через vmmanager 6. Там дырка, позволявшая через ссылку на iso передать ещё и команду, выполнявшуюся от root-а панелью.

Резюмируем, что с современным ИИ эксплуатация уязвимостей стала производиться гораздо быстрее.
Информации из анализа изменений достаточно для обнаружения ошибки и написания полноценного эксплоита в кратчайшие сроки.

Overview

27 Aug 2026
Published
01 Sep 2026
Updated
CVSS v3.1
HIGH (8.9)
EPSS
0.09%
KEV

Description

Ceph is an open-source distributed storage platform providing object, block, and file storage. In versions prior to 20.2.4 and 19.2.6, the CephX authentication protocol encrypts tickets with AES-128-CBC in an unauthenticated mode that uses a hard-coded initialization vector and no message authentication, allowing an attacker to forge credentials and gain cluster-wide access. Because the ciphertext is malleable and the monitor will encrypt attacker-chosen entity names, an attacker holding one low-privilege key and able to observe CephX traffic can use the monitor as an encryption oracle and splice ciphertext blocks into valid tickets for privileged entities such as Manager, MDS, and OSD. The same lack of authentication also lets an attacker with CephX permissions escalate privileges by flipping a single bit in a service ticket to set its allow_all field to true. This issue is fixed in versions 20.2.4 and 19.2.6.

Description

In fail2ban 0.10.5 through 1.1.1 before ddd879d, the sshd filter (config/filter.d/sshd.conf) accepts an "on <token>" suffix after the host address. Because OpenSSH logs the offered username verbatim, a remote unauthenticated attacker can use a username such as "x VICTIM-SOURCE-IP-ADDRESS on" to make fail2ban associate failed login attempts with an arbitrary source IP address and ban it (e.g., to block logins from a legitimate user). The default filter mode is affected.
