CWE ID 120


CVE-2024-39291 is a vulnerability in the Linux kernel that has been resolved. It affects multiple products, including Qtrc2o, ohMfk4, Qtrc2i, and many others. The vulnerability arises from a buffer size issue in the function gfx_v9_4_3_init_microcode in gfx_v9_4_3.c. The buffer 'ucode_prefix' is too small to accommodate the maximum possible length of the string being written into it, which can lead to truncation and potential exploitation. To remediate this issue, the size of the 'ucode_prefix' buffer has been reduced from 30 to 15. This vulnerability poses a high risk to organizations as it can be exploited locally with low privileges, resulting in high impact on integrity and confidentiality. The base severity score is rated as HIGH with a base score of 7.8 according to CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H.
