CVE-2026-97909

Status: ReceivedUnscored—

In the Linux kernel, the following vulnerability has been resolved:

ASoC: sti: initialize IRQ lock before requesting IRQ

uni_reader_init() registers the shared IRQ before initializing reader->irq_lock. A pending interrupt can invoke the handler while the lock is still uninitialized.

Initialize the lock before registering the IRQ so the interrupt path always sees valid lock state.

CVSS

NVD hasn't assigned a CVSS score to this CVE (common since the April 2026 policy change).

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
