CVE-2026-98412 Linux CVE debrief
A NULL-pointer dereference vulnerability was found in the Linux kernel's power sequencing code. The issue occurs in the `pwrseq_unit_new()` function when memory allocation fails in `pwrseq_unit_setup_deps()`. This vulnerability can cause a system crash or potentially allow an attacker to execute arbitrary code. Linux kernel maintainers and users should assess exposure and prioritize patching. The CVE Program record and NVD vulnerability detail provide official information about the vulnerability.
