Echo: linux: security update to 6.1.176-1

high Tenable Cloud Security Plugin ID 462038

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-46190)

Solution

Update the linux library and its related packages to version 6.1.176-1 or later.
