If a caller write more characters,\ncount is truncated to the max available space in \"simple_write_to_buffer\".\nBut afterwards a string terminator is written to the buffer at offset count\nwithout boundary check. The zero termination is written OUT-OF-BOUND.\n\nAdd a check that the given buffer is smaller then the buffer to prevent.","published":"2025-07-28T12:15:30.000Z","lastModified":"2026-07-30T06:23:20.000Z","status":"Modified","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-787"],"affected":["linux/linux kernel"],"epss":{"score":0.00162,"percentile":0.05349,"date":"2026-10-27","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 (0.16%).
