Vulnerability from fkie_nvd - Published: 2016-04-27 17:59 - Updated: 2026-06-17 00:44
Severity
Summary
The snd_seq_ioctl_remove_events function in sound/core/seq/seq_clientmgr.c in the Linux kernel before 4.4.1 does not verify FIFO assignment before proceeding with FIFO clearing, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted ioctl call.

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.
