Summary
A flaw was found in the Linux kernel's mtd: mchp23k256 driver. This driver, responsible for managing memory technology devices (MTD), incorrectly determined the capabilities of certain SPI (Serial Peripheral Interface) flash chips.
This could lead to the system misinterpreting the memory device's layout, potentially causing data corruption or system instability. Red Hat severity: Moderate — CVSS 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H).
Weakness: CWE-348. Red Hat lists Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9 as not affected.
