HCE3-SA-2026-0041 Important HCE 3.0 Security Fix(es): A flaw was found in the RandR extension, where the RRChangeProviderProperty function does not properly validate input. This issue leads to an integer overflow when computing the total size to allocate. (CVE-2025-49180) A flaw was found in the X Record extension. The RecordSanityCheckRegisterClients function does not check for an integer overflow when computing request length, which allows a client to bypass length checks. (CVE-2025-49179) A flaw was found in the X Rendering extension_x27;s handling of animated cursors. If a client provides no cursors, the server assumes at least one is present, leading to an out-of-bounds read and potential crash. (CVE-2025-49175) A flaw was found in the Big Requests extension. The request length is multiplied by 4 before checking against the maximum allowed size, potentially causing an integer overflow and bypassing the size check. (CVE-2025-49176) A flaw was found in the X server_x27;s request handling. Non-zero _x27;bytes to ignore_x27; in a client_x27;s request can cause the server to skip processing another client_x27;s request, potentially leading to a denial of service.
