Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified) openSUSE Tumbleweed versions prior to kernel-devel-7.0.12-1.1
Description A crash can occur during early boot if the kernel command line parameters hugepages, hugepagesz, or default hugepagesz are specified without the '=' separator. In this scenario, the early parameter parsing process passes a NULL value to the hugetlb add param() function, which then dereferences it within strlen(), leading to a system crash.
Recommendations Update to a version where the hugetlb add param() function is modified to reject NULL values and return -EINVAL. Update to kernel-devel-7.0.12-1.1 or a newer version.
