Acer Altos W2000h-W570h F4 R01.03.0018 was discovered to contain a stack overflow in the RevserveMem component. This vulnerability allows attackers to cause a Denial of Service (DoS) via injecting crafted shellcode into the NVRAM variable.
Security readout for executives and security teams
Plain-English summary
CVE-2022-41415 is a critical firmware vulnerability reported in Acer Altos W2000h-W570h F4 R01.03.0018. A remote, unauthenticated attacker may be able to crash affected systems and potentially affect confidentiality, integrity, and availability. Public affected-product data is incomplete.
Executive priority
Treat as urgent for any confirmed Acer Altos W2000h-W570h deployment because the score is critical and authentication is not required. Prioritize inventory first because public affected-product and fix information is incomplete.
Technical view
The CVE describes a CWE-787 out-of-bounds write stack overflow in the RevserveMem component. The reported trigger involves crafted data in an NVRAM variable. CVSS 3.1 is 9.8 with network attack vector, low complexity, no privileges, no user interaction, and high C/I/A impact.
Likely exposure
Exposure appears limited to environments running Acer Altos W2000h-W570h F4 R01.03.0018, but CVE affected-product metadata lists vendor and product as n/a. Asset inventory and firmware confirmation are required before scoping impact.
Exploitation context
The source bundle does not show CISA KEV listing or cited evidence of active exploitation. The public description indicates denial-of-service impact through crafted NVRAM input, with CVSS also rating confidentiality and integrity impacts high.
Researcher notes
Key gaps are vendor/product metadata marked n/a, no patch details in the provided sources, and no KEV evidence. Research should focus on firmware lineage, RevserveMem exposure boundaries, NVRAM variable handling, and vendor remediation status.
Mitigation direction
Check Acer or platform vendor guidance for fixed firmware or advisories.
Identify and prioritize any Acer Altos W2000h-W570h systems on F4 R01.03.0018.
Restrict reachable management or firmware interfaces to trusted administrative networks.
Plan replacement or isolation if no vendor-supported remediation is available.
Monitor affected systems for unexpected crashes, resets, or firmware anomalies.
Validation and detection
Inventory Acer Altos W2000h-W570h assets and record firmware versions.
Compare discovered firmware against F4 R01.03.0018 from the CVE description.
Review network paths to any exposed management or firmware update services.
Check the CVE record and vendor channels for updated affected-product or fix data.
Avoid proof-of-concept testing unless authorized and safely isolated.
