Zoom Clients

Remote code execution in Zoom Clients' annotator function allows a malicious meeting participant to compromise another participant's device by exploiting a use-after-free memory corruption flaw during a live meeting session. The CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H vector confirms network-accessible cross-participant exploitation with full CIA impact and scope change, requiring no in-meeting privileges but demanding high attack complexity consistent with UAF heap manipulation. No public exploit code has been identified at time of analysis, and no CISA KEV listing was found.
Remote code execution in Zoom Clients allows a malicious meeting participant to exploit a buffer over-write vulnerability in the annotator function, achieving code execution on another participant's device over the network. The CVSS 3.1 vector (AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H) reflects high-complexity exploitation with a changed scope, meaning impact extends beyond the Zoom process to the underlying host. No public exploit code and no CISA KEV listing have been identified at time of analysis, but the RCE potential and network vector make this a high-priority patch target for organizations relying on Zoom for sensitive communications.
Buffer over-read in the Zoom Clients annotator function allows any meeting participant to crash another participant's client, resulting in denial of service. The flaw (CWE-126) is exploitable remotely over the network with no privileges required but demands that the target be an active meeting participant with annotation data processed by their client. No active exploitation or public proof-of-concept code has been identified at time of analysis, and the impact is limited entirely to availability - no confidentiality or integrity effects are present.
