DEBIAN-CVE-2026-97029

Flatpak's process ID namespace separation does not prevent a sandboxed app's kill0, signal or killpg0, signal calls from reaching processes outside the sandbox that share the same process group. A malicious or compromised Flatpak app can use this to cause denial of service by terminating processe...

CVE-2026-97029

A vulnerability in Flatpak allows a sandboxed application to bypass process ID namespace separation . Specifically, the kill(0, signal) or killpg(0, signal) calls can reach processes outside the sandbox if they share the same process group . A malicious or compromised Flatpak app can exploit this...

CVE-2017-14179

Apport before 2.13 does not properly handle crashes originating from a PID namespace allowing local users to create certain files as root which an attacker could leverage to perform a denial of service via resource exhaustion, possibly gain root privileges, or escape from containers...

DEBIAN-CVE-2013-1958

The scmcheckcreds function in net/core/scm.c in the Linux kernel before 3.8.6 does not properly enforce capability requirements for controlling the PID value associated with a UNIX domain socket, which allows local users to bypass intended access restrictions by leveraging the time interval durin...

kernel: 'kill sig -1' must only apply to caller's pid namespace

The killsomethinginfo function in kernel/signal.c in the Linux kernel before 2.6.28 does not consider PID namespaces when processing signals directed to PID -1, which allows local users to bypass the intended namespace isolation, and send arbitrary signals to all processes in all namespaces, via ...
