Buffer Handling Vulnerability in Linux Kernel Affects Sound System

CVE-2026-98912

What is CVE-2026-98912?

A vulnerability in the Linux kernel's Advanced Linux Sound Architecture (ALSA) component allows improper handling of buffer sizes during event reading. The flaw is due to an incorrect check in the snd_seq_oss_read() function, which causes the reading process to prematurely stop when it encounters an event smaller than the available buffer size. This could lead to confusion regarding the end-of-file status, as incomplete events remain in the queue, potentially allowing unauthorized data access or manipulation. This vulnerability underscores the importance of properly validating buffer sizes to ensure system integrity and application security.
