Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

The “Use After Free” vulnerability in the Linux kernel’s traffic control index filter tcindex allows for privilege escalation. The imperfect hash area can be updated while packets are being processed, leading to a use-after-free when the ‘tcfextsexec’ function is called with a corrupted tcfext. A...

Astra Linux – Vulnerability in open-vm-tools

open-vm-tools contains a file descriptor hijacking vulnerability in the vmware-user-suid-wrapper. A malicious actor with non-root privileges may be able to hijack the /dev/uinput file descriptor, allowing them to simulate user inputs...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

A flaw was discovered in the Linux kernel. The existing KVM SEV API contains a vulnerability that allows a non-root host user-level application to crash the host kernel by creating a confidential guest VM instance in an AMD CPU that supports Secure Encrypted Virtualization SEV...

Astra Linux – Vulnerability in ofono

oFono CUSD Stack-based Buffer Overflow Code Execution Vulnerability. This vulnerability allows local attackers to execute arbitrary code on affected installations of oFono. An attacker must first obtain the ability to execute code on the target modem in order to exploit this vulnerability. The...

Astra Linux – Vulnerability in cups

OpenPrinting CUPS is an open-source printing system for Linux and other Unix-like operating systems. In versions 2.4.16 and earlier, a local unprivileged user could force cupsd to authenticate against a localhost IPP service controlled by the attacker, using a reusable “Authorization: Local…”...

Astra Linux – Vulnerability in xrdp

XRDPT is an open-source remote desktop protocol RDP server. In affected versions, an integer underflow leading to a heap overflow in the SESMAN server allows any unauthenticated attacker who can access the SESMAN server locally to execute code as root. This vulnerability has been patched in versi...

Astra Linux – Vulnerability in pmix

In versions of OpenPMIx PMIx prior to 4.2.6 and 5.0.x before 5.0.1, attackers could obtain ownership of arbitrary files due to a race condition during the execution of library code with a UID of 0...

Astra Linux – Vulnerability in exim4

Exim 4 before 4.94.2 has an improper neutralization of line delimiters, which is relevant in non-default configurations that enable Delivery Status Notification DSN. Certain uses of ORCPT= can cause a new line to be inserted into a spool header file, thereby indirectly allowing unauthenticated...

Astra Linux – Vulnerability in libblockdev, udisks2

A Local Privilege Escalation LPE vulnerability was discovered in libblockdev. Typically, the “allowactive” setting in Polkit allows a physically present user to perform certain actions based on the session type. Due to the way libblockdev interacts with the udisks daemon, a “allowactive” user on ...

Astra Linux – Vulnerability in avahi

The avahi-daemon-check-dns.sh script within the Debian avahi package, as of version 0.8-4, is executed as the root user via /etc/network/if-up.d/avahi-daemon. This script allows a local attacker to cause a denial of service or create arbitrary empty files through a symlink attack on files located...

Astra Linux – Vulnerability in exim4

Exim 4 before 4.94.2 allowed a heap-based buffer overflow in the queuerun function, through two sender options: -R and -S. This could lead to privilege escalation from the exim user to the root user...

Astra Linux – Vulnerability in exim4

Exim 4 before 4.94.2 allows Heap-based Buffer Overflows because it mishandles the "-F’.‘” syntax on the command line. This may allow privilege escalation from any user to root. This issue occurs due to the incorrect interpretation of negative sizes in the strncpy function...

Astra Linux – Vulnerability in sssd

A flaw was discovered in SSSD, where the sssctl command was vulnerable to shell command injection through the logs-fetch and cache-expire subcommands. This flaw allows an attacker to trick the root user into executing a specially crafted sssctl command, such as using sudo, in order to gain root...

Astra Linux – Vulnerability in Ceph

A privilege escalation flaw was discovered in Ceph. Ceph-crash.service allows a local attacker to escalate privileges to root through a crash dump, thereby exposing privileged information...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

A use-after-free vulnerability in the Linux Kernel traffic control index filter tcindex can be exploited to achieve local privilege escalation. The tcindexdelete function does not properly deactivate filters in the case of a perfect hash; moreover, it deletes the underlying structure without...

Astra Linux – Vulnerability in ofono

oFono CUSD AT Command Stack-based Buffer Overflow Code Execution Vulnerability. This vulnerability allows local attackers to execute arbitrary code on affected installations of oFono. An attacker must first obtain the ability to execute code on the target modem in order to exploit this...

Security Bulletin: This Power System update is being released to address CVE-2026-17063

Summary Power Systems Firmware is affected by a vulnerability in the interface between the BMC/FSP and the host system. An attacker with service account or root access to the BMC/FSP can access and disrupt host processor state, potentially affecting the managed system and all hosted partitions,...

CVE-2026-63343 Arbitrary File Read/Write: metadata.yaml symlink in image allows host filesystem access as root

Incus is a system container and virtual machine manager. Prior to version 7.3.0, a malicious image containing a metadata.yaml symlink pointing to an arbitrary host path allows an authenticated Incus user to read or overwrite any file on the host as root via the instance metadata API. The...

CVE-2026-48769

CVE-2026-48769 is a critical (CVSS 9.9) arbitrary file write vulnerability in Incus , a system container and virtual machine manager, affecting versions prior to 7.2.0 . The root cause is that the Incus client trusts a crafted Incus-Image-Hash header returned by a malicious image server, leading ...
