Status: AnalyzedMedium (5.5)—

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

ALSA: ad1816a: Fix potential NULL pointer deref in snd_card_ad1816a_pnp()

Use pr_warn() instead of dev_warn() when 'pdev' is NULL to avoid a potential NULL pointer dereference.

CVSS

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).
