Details

In the Linux kernel, the following vulnerability has been resolved: PCI: endpoint: Fix NULL pointer dereference for ->getfeatures() getfeatures ops of pciepcops may return NULL, causing NULL pointer dereference in pciepftestallocspace function. Let us add a check for pciepcfeature pointer in pciepftestbind before we access it to avoid any such NULL pointer dereference and return -ENOTSUPP in case pciepcfeature is not found. When the patch is not applied and EPC features is not implemented in the platform driver, we see the following dump due to kernel NULL pointer dereference.
