"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nPCI/AER: Avoid NULL pointer dereference in aer_ratelimit()\n\nWhen platform firmware supplies error information to the OS, e.g., via the\nACPI APEI GHES mechanism, it may identify an error source device that\ndoesn't advertise an AER Capability and therefore dev->aer_info, which\ncontains AER stats and ratelimiting data, is NULL.\n\npci_dev_aer_stats_incr() already checks dev->aer_info for NULL, but\naer_ratelimit() did not, leading to NULL pointer dereferences like this one\nfrom the URL below:\n\n {1}[Hardware Error]: Hardware error from APEI Generic Hardware Error Source: 0\n {1}[Hardware Error]: event severity: corrected\n {1}[Hardware Error]: device_id: 0000:00:00.0\n {1}[Hardware Error]: vendor_id: 0x8086, device_id: 0x2020\n {1}[Hardware Error]: aer_cor_status: 0x00001000, aer_cor_mask: 0x00002000\n BUG: kernel NULL pointer dereference, address: 0000000000000264\n RIP: 0010:___ratelimit+0xc/0x1b0\n pci_print_aer+0x141/0x360\n aer_recover_work_func+0xb5/0x130\n\n[8086:2020] is an Intel \"Sky Lake-E DMI3 Registers\" device that claims to\nbe a Root Port but does not advertise an AER Capability.\n\nAdd a NULL check in aer_ratelimit() to avoid the NULL pointer dereference.\nNote that this also prevents ratelimiting these events from GHES.\n\n[bhelgaas: add crash details to commit log]"
