Linux Kernel vulnerability
Linux Kernel cgroups v1 release_agent feature contains an improper authentication vulnerability enabling privilege escalation.
Verdict
Today item — known-exploited.
An unauthenticated local attacker can exploit cgroups v1 release_agent functionality to escalate privileges on affected Linux systems. The vulnerability has been observed in active exploitation.
01
Is it exploitable?
— the evidence, ranked above the scoreExploit available
Public proof-of-concept exploit code is cataloged for this vulnerability.We link the existence of the exploit; we do not host or redistribute payloads.
Reported exploitation
4 independent public reports of in-the-wild exploitation are cataloged.Distinct reporting sources (vendor, incident response, government); open them for the underlying claims.
Exploited in the wild
Listed in the CISA Known Exploited Vulnerabilities catalog (added 2026-06-02).
Probability (EPSS)
EPSS 0.05528 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Linux, Kernel. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-287 Improper Authentication — weakness family: Authentication.CWE — CNA-assigned (CVE.org); the weakness class drives how the flaw is exploited.
Public exploit available
Public exploit tooling is catalogued for this CVE (a functional/weaponized public exploit). Catalog entries: Metasploit module. We link the catalog page(s) only — no payload or code is hosted or restated here.Link, never host — the catalog page is the source; basicsecurity.net does not redistribute payloads.
02
Who’s exploiting it?
— attribution turns risk into urgencyAttribution not established
No confirmed (advisory-backed) threat-actor attribution is established for this record. Absence of a named actor is not absence of compromise — see Coverage & confidence.
03
Why it matters
— the attack path, told twice: adversary, then board1
Front door — unauthenticated access narrative 1
Attacker
Gain local system access to a Linux host running vulnerable kernel.
Business
Attacker establishes initial foothold on infrastructure.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
Manipulate cgroups v1 release_agent configuration to execute arbitrary code with elevated privileges.
Business
Attacker bypasses access controls and authentication mechanisms.
3
Lateral reach — past segmentation narrative 3
Attacker
Achieve root or administrative privilege level on the compromised system.
Business
Attacker gains complete control over affected host and can access sensitive data or pivot to other systems.
04
What to do
— defensible action- Remediate per the vendor advisory — confirm the fixed build for your version and verify exposure.1
Say it to the boardA vulnerability with this evidence profile is a defensible budget line, not a backlog ticket — fund the change against the proof above.
