CVE-2026-23149 |
|
| Software afectado | LINUX KERNEL |
|
In the Linux kernel, the following vulnerability has been resolved: drm: Do not allow userspace to trigger kernel warnings in drm_gem_change_handle_ioctl() Since GEM bo handles are u32 in the uapi and the internal implementation uses idr_alloc() which uses int ranges, passing a new handle larger than INT_MAX trivially triggers a kernel warning: idr_alloc(): ... if (WARN_ON_ONCE(start < 0)) return -EINVAL; ... Fix it by rejecting new handles above INT_MAX and at the same time make the end limit calculation more obvious by moving into int domain. |
