Vulnerability from github – Published: 2024-11-08 06:30 – Updated: 2026-05-12 15:30
VLAI
Details
In the Linux kernel, the following vulnerability has been resolved:
ALSA: firewire-lib: Avoid division by zero in apply_constraint_to_size()
The step variable is initialized to zero. It is changed in the loop, but if it's not changed it will remain zero. Add a variable check before the division.
The observed behavior was introduced by commit 826b5de90c0b ("ALSA: firewire-lib: fix insufficient PCM rule for period/buffer size"), and it is difficult to show that any of the interval parameters will satisfy the snd_interval_test() condition with data from the amdtp_rate_table[] table.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
