Astra Linux – Vulnerability in Linux 5.10
A flaw was discovered in the way the “flags” member of the new pipe buffer structure lacked proper initialization in the copypagetoiterpipe and pushpipe functions of the Linux kernel. As a result, these members could contain stale values. An unprivileged local user could exploit this flaw to writ...
kernel: Read root-owned files as an unprivileged user
A vulnerability was found in the Linux kernel that allows an unprivileged local user to read sensitive files normally restricted to the root user. The flaw occurs during process exit, where a brief window allows an attacker to intercept file access from a privileged process before it fully...
PackageKit: race condition vulnerability leads to arbitrary package installation as root
A flaw was found in PackageKit. A time-of-check time-of-use TOCTOU race condition on transaction flags allows unprivileged users to install packages as root, resulting in a local privilege escalation...
Important: kernel-rt security update
The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fixes: kernel: "Fragnesia" is a variant of Dirty Frag vulnerability in the ESP/XFRM leading to Local Privilege Escalation LPE vulnerability in th...
FreeBSD -- Missing validation in ptrace(PT_SC_REMOTE)
Problem Description: ptracePTSCREMOTE failed to properly validate parameters for the syscall2 and syscall2 meta-system calls. As a result, a user with the ability to debug a process may trigger arbitrary code execution in the kernel, even if the target process has no special privileges. Impact: T...
Amazon Linux 2023 : firewalld, firewalld-filesystem, firewalld-test (ALAS2023-2026-1636)
It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2026-1636 advisory. A flaw was found in firewalld. A local unprivileged user can exploit this vulnerability by mis-authorizing two runtime D-Bus Desktop Bus setters, setZoneSettings2 and setPolicySettings. This...
FreeBSD -- Stack buffer overflow via setcred(2)
Problem Description: The setcred2 system call is only available to privileged users. However, before the privilege level of the caller is checked, the user-supplied list of supplementary groups is copied into a fixed-size kernel stack buffer without first validating its length. If the supplied li...
libcap: libcap: Privilege escalation via TOCTOU race condition in cap_set_file()
A flaw was found in libcap. A local unprivileged user can exploit a Time-of-check-to-time-of-use TOCTOU race condition in the capsetfile function. This allows an attacker with write access to a parent directory to redirect file capability updates to an attacker-controlled file. By doing so,...
PackageKit: race condition vulnerability leads to arbitrary package installation as root
A flaw was found in PackageKit. A time-of-check time-of-use TOCTOU race condition on transaction flags allows unprivileged users to install packages as root, resulting in a local privilege escalation...
kernel: "Dirty Frag" ESP XFRM variant is a new universal Local Privilege Escalation (LPE) vulnerability in the Linux kernel
A flaw was found in the Linux kernel's xfrm-ESP and RxRPC subsystems. Unsafe in-place cryptographic processing of shared socket buffer fragments allows a low-privileged local attacker to corrupt page-cache contents of readable files, including sensitive system files, and gain root privileges. The...
libcap: libcap: Privilege escalation via TOCTOU race condition in cap_set_file()
A flaw was found in libcap. A local unprivileged user can exploit a Time-of-check-to-time-of-use TOCTOU race condition in the capsetfile function. This allows an attacker with write access to a parent directory to redirect file capability updates to an attacker-controlled file. By doing so,...

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,...
CVE-2026-32244
Discourse: Cached outdated AI summaries can leak removed content to anonymous/unprivileged users who cannot regenerate summaries. Affected in versions prior to 2026.1.4, 2026.3.1, 2026.4.1 and 2026.5.0-latest. Fixed in those versions. Remediation: upgrade to 2026.1.4, 2026.3.1, 2026.4.1, or 2026....
SUSE CVE-2026-6473
Integer wraparound in multiple PostgreSQL server features allows an unprivileged database user to cause the server to undersize an allocation and write out-of-bounds. This may execute arbitrary code as the operating system user running the database. In applications that pass gigabyte-scale user...
