"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nagp/amd64: Fix broken error propagation in agp_amd64_probe()\n\nA NULL pointer dereference was observed in the AMD64 AGP driver when\nrunning in a virtualized environment (e.g. qemu/kvm) without a physical\nAMD northbridge. The crash occurs in amd64_fetch_size() when attempting\nto dereference the pointer returned by node_to_amd_nb(0).\n\nThe root cause of this crash is broken error propagation in\nagp_amd64_probe(): When no AMD northbridges are found, cache_nbs()\ncorrectly returns -ENODEV. However, the probe function erroneously\nchecks the return value against exactly -1, rather than < 0.\n\nAs a result, the hardware absence error is masked, allowing the driver\nto improperly proceed with initialization. It eventually calls\nagp_add_bridge(), which invokes amd64_fetch_size(). Since the hardware\ndoes not exist, node_to_amd_nb(0) returns NULL, leading to a General\nProtection Fault (GPF) when accessing its ->misc member.\n\nFix the issue by correcting the error check in agp_amd64_probe() to\nabort properly when cache_nbs() returns any negative error code. This\nprevents the driver from erroneously proceeding without hardware, thereby\navoiding the subsequent NULL pointer dereference at its source."
