Linux Kernel vulnerability
Linux Kernel integer overflow in create_elf_tables() allows unprivileged local users to escalate privileges via SUID binaries.
Verdict
Today item — known-exploited.
An integer overflow in the Linux Kernel's create_elf_tables() function enables local privilege escalation when an unprivileged user accesses a SUID or privileged binary, leading to full system compromise.
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
2 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 2026-01-26).
Probability (EPSS)
EPSS 0.14806 — 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-190 Integer Overflow — weakness family: Memory safety.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 gain local system access as an unprivileged user.
Business
An attacker establishes initial foothold on the system.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I identify and execute a SUID or privileged binary on the system.
Business
The attacker identifies a vector to trigger the vulnerable code path.
3
Lateral reach — past segmentation narrative 3
Attacker
I trigger an integer overflow in create_elf_tables() during binary execution.
Business
Memory corruption occurs within a privileged process context.
4
Data at risk — exfiltration narrative 4
Attacker
I escalate my privileges to root or system level through the overflow.
Business
The attacker gains complete control of the affected system.
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.
