CVE-2026-89952

Estado: RecibidaSin puntuar—

In the Linux kernel, the following vulnerability has been resolved:

mtd: rawnand: validate ONFI extended parameter page sections

nand_flash_detect_ext_param_page() allocates the length declared by the ONFI parameter page, then treats the data as a fixed header followed by variable-length sections. It reads that header and advances over sections without first proving that the fixed page and each current section fit in the allocation.

Reject pages shorter than the fixed header, track the remaining variable area while walking sections, and require the ECC section to contain every field read from struct onfi_ext_ecc_info. Use device-scoped diagnostics that identify the malformed ONFI section.
