Answer in brief
CVE-2026-45896 records a High severity (CVSS 7.8) vulnerability in mtd: intel-dg: Fix accessing regions before setting nregions. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 7.8. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

In the Linux kernel, the following vulnerability has been resolved: mtd: intel-dg: Fix accessing regions before setting nregions The regions array is counted by nregions, but it's set only after accessing it: [] UBSAN: array-index-out-of-bounds in drivers/mtd/devices/mtd_intel_dg.c:750:15 [] index 0 is out of range for type '<unknown> [*]' Fix it by also fixing an undesired behavior: the loop silently ignores ENOMEM and continues setting the other entries.
