CVE-2025-39751 Details
Description
Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.
A buffer overflow vulnerability has been identified in the Linux kernel's Advanced Linux Sound Architecture (ALSA) component, specifically within the High Definition Audio (HDA) driver for the CA0132 codec. The issue arises in the 'add_tuning_control' function, where the 'sprintf' function is used to format strings. This can potentially lead to a buffer overflow if either string argument exceeds 44 bytes. The vulnerability has been addressed by replacing 'sprintf' with 'snprintf', which restricts the string length and prevents the overflow.
Users can upgrade to the latest version of the Linux kernel, where this vulnerability has been fixed. Instructions for upgrading the kernel can be found in the official Linux kernel documentation.
