Description

In the Linux kernel, the following vulnerability has been resolved: can: etas_es58x: fix potential NULL pointer dereference on udev->serial The driver assumed that es58x_dev->udev->serial could never be NULL. While this is true on commercially available devices, an attacker could spoof the device identity providing a NULL USB serial number. That would trigger a NULL pointer dereference. Add a check on es58x_dev->udev->serial before accessing it.

Affected configurations

• linux linux kernel (>= 6.2 < 6.6.79) • linux linux kernel (>= 6.7 < 6.12.16) • linux linux kernel (>= 6.13 < 6.13.4) • linux linux kernel 6.14
