Astra Linux - Vulnerability in Golang-1.19

On Unix platforms, the Go runtime behaves differently when a binary is run with the setuid/setgid bits enabled. This can be dangerous in certain situations, such as when dumping memory state or assuming the status of standard I/O file descriptors. If a setuid/setgid binary is executed with standa...

Linux Distros Unpatched Vulnerability : CVE-2026-15226

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - A sandbox confinement bypass vulnerability exists in Canonical snapd within its internal execution environment compiler snap-confine. The default seccomp securi...

CVE-2026-15226

A sandbox confinement bypass vulnerability exists in Canonical snapd within its internal execution environment compiler snap-confine. The default seccomp security templates generated by the engine to restrict system calls do not filter or reject process operations capable of creating or...

CVE-2026-15226

Canonically reported vulnerability CVE-2026-15226 affects Canonical snapd’s sandboxed environment (snap-confine). The issue: default seccomp templates did not filter or reject operations to create/manipulate file execution flags with set-user-id attributes, allowing a strictly confined snap to co...

TencentOS Server 2: glibc (TSSA-2025:1030)

The version of Tencent Linux installed on the remote TencentOS Server 2 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2025:1030 advisory. Package updates are available for TencentOS Server 2 that fix the following vulnerabilities:...

CVE-2026-49414 ASLR bypass for setuid executables via procctl(2)

The ELF image activator cleared per-process ASLR preference flags for setuid binaries after the code that computes the PIE base address, rather than before. As a result, a user-requested ASLR disable was still in effect at the point where the base address was chosen. An unprivileged local user ca...

CVE-2026-49414

The FreeBSD kernel contains a vulnerability (CVE-2026-49414) where the ELF image activator clears per-process ASLR preference flags for setuid binaries after the code computes the PIE base address. This allows an unprivileged local user to call procctl(2) before execve(2) to disable ASLR, simplif...

CVE-2026-48980

The PAM module pam_usb is affected by a local-access vulnerability in earlier releases (pre-0.9.2) where getenv() in a PAM context returns attacker-controlled values for XRDP_SESSION, DISPLAY, and TMUX when the environment is manipulated by a local user. These values influence local-vs-remote ses...

CVE-2026-48980 pam_usb: getenv() used in PAM context allows environment variable injection into local-check logic

pamusb provides hardware authentication for Linux using removable media. In versions prior to 0.9.2, getenv environment variables XRDPSESSION, DISPLAY and TMUX allow environment variable injection into local-check logic. These environment variables influence whether a current session is local or...
