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. |
