Linux Kernel vulnerability
Linux Kernel RDS protocol implementation contains improper input validation in sendmsg and recvmsg system calls, allowing local users to escalate privileges through crafted messages.
Verdict
Today item — known-exploited.
A local privilege escalation vulnerability in the Linux Kernel's Reliable Datagram Sockets protocol implementation. Attackers with local system access can exploit improper input validation to gain elevated privileges.
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
1 independent public report 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 2023-05-12).
Probability (EPSS)
EPSS 0.11217 — 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-20 Improper Input Validation.CWE assignment from the public NVD record; the weakness class drives how the flaw is exploited.
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
I craft malicious RDS protocol messages using sendmsg and recvmsg system calls to bypass input validation checks.
Business
An unprivileged local user gains unauthorized administrative access to the system.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I leverage elevated privileges to access sensitive system resources and data restricted to administrators.
Business
Confidentiality and integrity of system data are compromised, enabling further lateral movement or data exfiltration.
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.
