AI-suggested
A fix has been applied to the Linux kernel to add proper NULL checks and reorder function calls to prevent the NULL pointer dereference. Users should update to a kernel version that includes this fix. Patch status is confirmed resolved in the Linux kernel source. No additional mitigation steps are indicated.
Description
A NULL pointer dereference vulnerability in the Linux kernel's usbip vhci_hcd driver was resolved. The issue occurs because platform_get_drvdata() can return NULL if a VHCI host controller's probe fails, but the code did not properly check for this before dereferencing. This could lead to a kernel crash or denial of service. The fix adds a NULL check before dereferencing and reorders function calls to handle error paths correctly.
