CVE-2026-23149

  2. Vulnerabilities (CVE)
  3. CVE-2026-23149
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.

Summary
  • (es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: drm: No permitir que el espacio de usuario active advertencias del kernel en drm_gem_change_handle_ioctl() Dado que los identificadores GEM bo son u32 en la uapi y la implementación interna utiliza idr_alloc() que usa rangos int, pasar un nuevo identificador mayor que INT_MAX desencadena trivialmente una advertencia del kernel: idr_alloc(): ... if (WARN_ON_ONCE(start &lt; 0)) return -EINVAL; ... Se soluciona rechazando los nuevos identificadores superiores a INT_MAX y al mismo tiempo haciendo más obvio el cálculo del límite final al moverlo al dominio int.
