  2. Vulnerabilities (CVE)
  3. CVE-2026-46284
In the Linux kernel, the following vulnerability has been resolved: mm/hugetlb: fix early boot crash on parameters without '=' separator If hugepages, hugepagesz, or default_hugepagesz are specified on the kernel command line without the '=' separator, early parameter parsing passes NULL to hugetlb_add_param(), which dereferences it in strlen() and can crash the system during early boot. Reject NULL values in hugetlb_add_param() and return -EINVAL instead.

Summary
  • (es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: mm/hugetlb: corrige un fallo de arranque temprano en parámetros sin el separador '=' Si hugepages, hugepagesz o default_hugepagesz se especifican en la línea de comandos del kernel sin el separador '=', el análisis temprano de parámetros pasa NULL a hugetlb_add_param(), lo que lo desreferencia en strlen() y puede provocar un fallo del sistema durante el arranque temprano. Rechazar valores NULL en hugetlb_add_param() y devolver -EINVAL en su lugar.
