On 64-bit systems, this makes the\npassed length 8x larger than intended.\n\nInside spi_nor_print_flags(), the 'names_len' argument is used to\nbounds-check the 'names' array access. An out-of-bounds read occurs\nif a flag bit is set that exceeds the array's actual element count\nbut is within the inflated byte-size count.\n\nCorrect this by using ARRAY_SIZE() to pass the actual number of\nstring pointers in the array.\n\n## Affected\n\n- `linux_kernel >= 5.19, < 6.6.140`\n- `linux_kernel >= 6.7, < 6.12.88`\n- `linux_kernel >= 6.13, < 6.18.30`\n- `linux_kernel >= 6.19, < 7.0.7`\n- `linux_kernel = 7.1`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `linux_kernel 7.0.7`","depth":"twilight","depthScore":39,"depthScoreParts":{"impact":39.1,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
