CVE-2025-38281

Status: AnalyzedMedium (5.5)—

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

wifi: mt76: mt7996: Add NULL check in mt7996_thermal_init

devm_kasprintf() can return a NULL pointer on failure,but this returned value in mt7996_thermal_init() is not checked. Add NULL check in mt7996_thermal_init(), to handle kernel NULL pointer dereference error.

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).
