Usb core calls usb_ep0_reinit() in this case,\nwhich ends up calling xhci_configure_endpoint().\n\nOn Panther point xHC the xhci_configure_endpoint() function will\nadditionally check and reserve bandwidth in software. Other hosts do\nthis in hardware\n\nIf xHC address device command fails then a new xhci_virt_device structure\nis allocated as part of re-enabling the slot, but the bandwidth table\npointers are not set up properly here.\nThis triggers the NULL pointer dereference the next time usb_ep0_reinit()\nis called and xhci_configure_endpoint() tries to check and reserve\nbandwidth\n\n[46710.713538] usb 3-1: new full-speed USB device number 5 using xhci_hcd\n[46710.713699] usb 3-1: Device not responding to setup address.\n[46710.917684] usb 3-1: Device not responding to setup address.\n[46711.125536] usb 3-1: device not accepting address 5, error -71\n[46711.125594] BUG: kernel NULL pointer dereference, address: 0000000000000008\n[46711.125600] #PF: supervisor read access in kernel mode\n[46711.125603] #PF: error_code(0x0000) - not-present page\n[46711.125606] PGD 0 P4D 0\n[46711.125610] Oops: Oops: 0000 [#1] PREEMPT SMP PTI\n[46711.125615] CPU: 1 PID: 25760 Comm: kworker/1:2 Not tainted 6.10.3_2 #1\n[46711.125620] Hardware name: Gigabyte Technology Co., Ltd.\n[46711.125623] Workqueue: usb_hub_wq hub_event [usbcore]\n[46711.125668] RIP: 0010:xhci_reserve_bandwidth (drivers/usb/host/xhci.c\n\nFix this by making sure bandwidth table pointers are set up correctly\nafter a failed address device command, and additionally by avoiding\nchecking for bandwidth in cases like this where no actual endpoints are\nadded or removed, i.e. only context for default control endpoint 0 is\nevaluated.", "affected": [ { "vendor": "Linux", "product": "Linux", "defaultStatus": "unaffected", "versions": [ { "version": "651aaf36a7d7b36a58980e70133f9437d4f6d312", "status": "affected", "versionType": "git", "lessThan": "ef0a0e616b2789bb804a0ce5e161db03170a85b6" }, { "version": "651aaf36a7d7b36a58980e70133f9437d4f6d312", "status": "affected", "versionType": "git", "lessThan": "a57b0ebabe6862dce0a2e0f13e17941ad72fc56b" }, { "version": "651aaf36a7d7b36a58980e70133f9437d4f6d312", "status": "affected", "versionType": "git", "lessThan": "0f0654318e25b2c185e245ba4a591e42fabb5e59" }, { "version": "651aaf36a7d7b36a58980e70133f9437d4f6d312", "status": "affected", "versionType": "git", "lessThan": "365ef7c4277fdd781a695c3553fa157d622d805d" }, { "version": "651aaf36a7d7b36a58980e70133f9437d4f6d312", "status": "affected", "versionType": "git", "lessThan": "5ad898ae82412f8a689d59829804bff2999dd0ea" }, { "version": "651aaf36a7d7b36a58980e70133f9437d4f6d312", "status": "affected", "versionType": "git", "lessThan": "6b99de301d78e1f5249e57ef2c32e1dec3df2bb1" }, { "version": "651aaf36a7d7b36a58980e70133f9437d4f6d312", "status": "affected", "versionType": "git", "lessThan": "8fb9d412ebe2f245f13481e4624b40e651570cbd" }, { "version": "651aaf36a7d7b36a58980e70133f9437d4f6d312", "status": "affected", "versionType": "git", "lessThan": "af8e119f52e9c13e556be9e03f27957554a84656" } ] }, { "vendor": "Linux", "product": "Linux", "defaultStatus": "affected", "versions": [ { "version": "4.15", "status": "affected" }, { "version": "0", "status": "unaffected", "versionType": "semver", "lessThan": "4.15" }, { "version": "4.19.321", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "4.19.*" }, { "version": "5.4.283", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.4.*" }, { "version": "5.10.225", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.10.*" }, { "version": "5.15.166", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.15.*" }, { "version": "6.1.107", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.1.*" }, { "version": "6.6.48", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.6.*" }, { "version": "6.10.7", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.10.*" }, { "version": "6.11", "status": "unaffected", "versionType": "original_commit_for_fix", "lessThanOrEqual": "*" } ] } ] } } }
