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.","published":"2026-05-28T10:16:35.000Z","lastModified":"2026-10-15T02:19:49.000Z","status":"Modified","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H"},"cwe":["CWE-125"],"affected":["linux/linux kernel"],"epss":{"score":0.00131,"percentile":0.02695,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.13%).
