CVE-2025-38680
Estado: ModificadaAlta (7.1)—
In the Linux kernel, the following vulnerability has been resolved:
media: uvcvideo: Fix 1-byte out-of-bounds read in uvc_parse_format()
The buffer length check before calling uvc_parse_format() only ensured that the buffer has at least 3 bytes (buflen > 2), buf the function accesses buffer[3], requiring at least 4 bytes.
This can lead to an out-of-bounds read if the buffer has exactly 3 bytes.
Fix it by checking that the buffer has at least 4 bytes in uvc_parse_format().
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H
