Out-of-bounds read in Capability Access Management Service (camsvc) allows an authorized attacker to disclose information locally.
AI Analysis
Technical Summary
This vulnerability involves an out-of-bounds read (CWE-125) in the Capability Access Management Service (camsvc) component of Microsoft Windows 11 Version 24H2 (build 10.0.26100.0). An attacker with local authorized access can exploit this flaw to read memory beyond intended boundaries, potentially disclosing sensitive information. The CVSS v3.1 base score is 5.5, reflecting medium severity with high confidentiality impact but no integrity or availability impact. The attack vector requires local access with low complexity and no user interaction. Microsoft has released a patch to remediate this vulnerability.
Potential Impact
An authorized local attacker can exploit this vulnerability to read memory outside of expected bounds within the camsvc process, leading to potential disclosure of sensitive information. There is no impact on system integrity or availability. No known exploits are reported in the wild at this time.
Mitigation Recommendations
A patch is available from Microsoft to address this vulnerability. It is recommended to apply the official update for Windows 11 Version 24H2 to remediate this issue. Since this is a local vulnerability requiring authorized access, applying the patch will effectively mitigate the risk.
