| Description | In the Linux kernel, the following vulnerability has been resolved:
i2c: amd-mp2: Unregister callback on adapter add failure
amd_mp2_register_cb() stores the platform I2C context in the MP2 PCI
driver's callback table before the adapter is registered. If
i2c_add_adapter() fails, probe returns and devres frees the context,
but the PCI driver can still dereference the stale pointer from its IRQ
and system-sleep callbacks.
Unregister the callback before returning the adapter registration error. |
