CVE-2026-46190

Alta 7.1

In the Linux kernel, the following vulnerability has been resolved: mtd: spi-nor: debugfs: fix out-of-bounds read in spi_nor_params_show() Sashiko noticed an out-of-bounds read [1]. In spi_nor_params_show(), the snor_f_names array is passed to spi_nor_print_flags() using sizeof(snor_f_names). Since snor_f_names is an array of pointers, sizeof() returns the total number of bytes occupied by the pointers (element_count * sizeof(void *)) rather than the element count itself. On 64-bit systems, this makes the passed length 8x larger than intended. Inside spi_nor_print_flags(), the 'names_len' argument is used to bounds-check the 'names' array access. An out-of-bounds read occurs if a flag bit is set that exceeds the array's actual element count but is within the inflated byte-size count. Correct this by using ARRAY_SIZE() to pass the actual number of string pointers in the array.
