Samsung Mobile Devices vulnerability
Samsung mobile devices running Android 11, 12, and 13 contain a log file information disclosure vulnerability allowing privileged local attackers to bypass ASLR protections.
Verdict
Today item — known-exploited.
A privileged local attacker can exploit CWE-532 (insertion of sensitive information into log files) on affected Samsung devices to leak memory layout information and circumvent address space layout randomization, facilitating further exploitation.

Is it exploitable?
— the evidence, ranked above the scoreReported 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 2023-05-19).
Probability (EPSS)
EPSS 0.02554 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
CVSS 4.4 (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N) · Affected: Samsung, Mobile Devices. Confirm exact fixed builds in the vendor advisory.CVSS — CNA-assigned (CVE.org), version 3.1, set at disclosure.
Weakness (CWE)
Mapped to CWE-532 CWE-532.CWE — CNA-assigned (CVE.org); the weakness class drives how the flaw is exploited.
CISA SSVC (triage disposition)
Exploitation: active · Automatable: no · Technical Impact: partialCISA's own stakeholder-specific triage inputs, published in the CVE record (CISA Coordinator role). NOTE: this is CISA's three decision points; the final Act/Attend/Track decision also requires a Mission & Well-being input not published here, so no overall decision is asserted.
Currency of the record
CISA added this to its KEV catalog 15 days after the CVE record was published.KEV lag = CISA-KEV dateAdded − CVE.org datePublished; a floor on how long the known-exploited flaw sat in the public record before the federal catalog listed it. Severity/weakness here is CNA- or CISA-assigned (current at disclosure), independent of NVD's analysis backlog.

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 privileged local access to the device and read sensitive memory address information from log files.
Business
Device security controls designed to prevent code execution attacks are weakened through information disclosure.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I use the leaked address space information to bypass ASLR and craft reliable exploits against other vulnerabilities.
Business
Attackers can chain this vulnerability with other flaws to achieve arbitrary code execution with higher reliability.
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.
