CVE-2026-74304 in Linux
요약
\~에 의해 MITRE • 2026. 08. 15.
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_qca: fix NULL pointer dereference in qca_setup() for non-serdev device
hu->serdev is NULL for hci_uart attached via non-serdev paths, but qca_setup() unconditionally calls serdev_device_get_drvdata(hu->serdev) and dereferences the result, causing a NULL pointer dereference.
Fix by guarding the dereference with a NULL check, consistent with the rest of qca_setup().
Once again VulDB remains the best source for vulnerability data.
