Design/Logic Flaw

An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces subsystem was found in the way users have access to some less privileged process that are controlled by cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1...

CVE-2021-4197

CVE-2021-4197 is a Linux kernel vulnerability in the cgroup process migration permission checks. A local attacker could escalate privileges due to incorrect permission validation for cgroup-associated processes (affecting both cgroup v1 and v2). The issue is described across multiple sources as a...

kernel: cgroups v1 release_agent feature may allow privilege escalation

A vulnerability was found in the Linux kernel’s cgroupreleaseagentwrite in the kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups v1 releaseagent feature to escalate privileges and bypass the namespace isolation unexpectedly...

kernel: local privilege escalation by exploiting the fsconfig syscall parameter leads to container breakout

A use-after-free flaw was found in cgroup1parseparam in kernel/cgroup/cgroup-v1.c in the Linux kernel's cgroup v1 parser. A local attacker with a user privilege could cause a privilege escalation by exploiting the fsconfig syscall parameter leading to a container breakout and a denial of service ...

Bug in the Linux Kernel Allows Privilege Escalation, Container Escape

To go along with the “Dirty Pipe” Linux security bug coming to light, two researchers from Huawei – Yiqi Sun and Kevin Wang – have discovered a vulnerability in the “control groups” feature of the Linux kernel which allows attackers to escape containers, escalate privileges and execute arbitrary...
