systemd: systemd: Arbitrary code execution or Denial of Service via spurious IPC API call data
A flaw was found in systemd, a system and service manager. An unprivileged user can exploit this vulnerability by making an Inter-Process Communication IPC API call with spurious data. In older versions v249 and earlier, this can lead to stack overwriting with attacker-controlled content,...

kernel: rtnetlink: add missing netlink_ns_capable() check for peer netns
A flaw was found in the Linux kernel's rtnetlink component. An unprivileged local user, leveraging a user namespace, can exploit a missing CAPNETADMIN capability check in the rtnlnewlink function. This allows the user to create paired network devices in arbitrary network namespaces, including the...

CVE-2026-44094
An unauthenticated remote attacker can enforce the system to fall back to a firmware partition with an insecure configuration including default credentials. This could allow the attacker to gain SSH access to the system as an unprivileged user "user-app". Charging could be interrupted...
CVE-2026-44094 Fallback to second RAUC slot with default credentials
An unauthenticated remote attacker can enforce the system to fall back to a firmware partition with an insecure configuration including default credentials. This could allow the attacker to gain SSH access to the system as an unprivileged user "user-app". Charging could be interrupted...
K000162478: PostgreSQL vulnerability CVE-2026-6637
Security Advisory Description Stack buffer overflow in PostgreSQL module "refint" allows an unprivileged database user to execute arbitrary code as the operating system user running the database. A distinct attack is possible if the application declares a user-controlled column as a "refint"...
OPENSUSE-SU-2026:21473-1 Security update for apptainer
This update for apptainer fixes the following issues: Changes in apptainer: - Update to version 1.5.3: If the ptrace system call does not work while building an image as an unprivileged user, skip using PRoot to preserve file ownership and print an INFO message. Bind getopt from the host when usi...
UBUNTU-CVE-2026-17523
A flaw was found in the kernel. An unprivileged local user can exploit this vulnerability to execute arbitrary code within the kernel, which leads to a local privilege escalation LPE. This allows the attacker to gain root privileges and take full control of the affected system...
CVE-2026-64459
A flaw was found in the Linux kernel's TCP-AO TCP Authentication Option implementation. An unprivileged local user can exploit a use-after-free vulnerability in the tcpaodestroysock function. By manipulating TCP sockets with TCPMD5SIG and TCPAOADDKEY, an attacker can trigger a race condition duri...
Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12
In the Linux kernel, the following vulnerability has been resolved: ppp: The requirement for CAPNETADMIN in the target netns is necessary for unattached IOCTls. The opening of /dev/ppp is currently allowed for file-fcred-userns, while unattached administrative IOCTls operate on...

CVE-2026-16552
Rejected reason: The reported issue is invalid, as it requires root privileges to reproduce, and it is out of scope of the threat model of the affected component...
DEBIAN-CVE-2026-16552
A flaw was found in systemd-tmpfiles. When processing a tmpfiles.d configuration entry that writes to a file, systemd-tmpfiles can follow a symbolic link placed by an unprivileged local user, and an existing safety check does not detect this specific case because it always treats transitions away...
CVE-2026-16552
The CVE-2026-16552 entries describe a vulnerability in systemd-tmpfiles: when processing tmpfiles.d entries that write to a file, an unprivileged local user can cause systemd-tmpfiles to follow a symbolic link, potentially redirecting a privileged write to an attacker-controlled file. The highest...
