CVE-2026-45896 Details
Description
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.
A vulnerability in the Linux kernel's Intel graphics non-volatile memory device driver has been addressed. The issue was an array index out-of-bounds error in the regions array, which is counted by nregions but was accessed before nregions was set. This flaw, detected by Undefined Behavior Sanitizer, could lead to memory access errors. The vulnerability arose because the driver loop ignored memory allocation errors and continued processing, potentially causing further issues.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. The patch is available in the Linux stable tree.
