Title
pps: Fix a use-after-free
Summary
In the Linux kernel, the following vulnerability has been resolved: pps: Fix a use-after-free On a board running ntpd and gpsd, I'm seeing a consistent use-after-free in sys_exit() from gpsd when rebooting: pps pps1: removed ------------[ cut here ]------------ kobject: '(null)' (00000000db4bec24): is not initialized, yet kobject_put() is being called.

Kernel panic - not syncing: Oops - BUG: Fatal exception This happens because pps_device_destruct() frees the pps_device with the embedded cdev immediately after calling cdev_del(), but, as the comment above cdev_del() notes, fops for previously opened cdevs are still callable even after cdev_del() returns. I think this bug has always been there: I can't explain why it suddenly started happening every time I reboot this particular board. In commit d953e0e837e6 ("pps: Fix a use-after free bug when unregistering a source."), George Spelvin suggested removing the embedded cdev. That seems like the simplest way to fix this, so I've implemented his suggestion, using __register_chrdev() with pps_idr becoming the source of truth for which minor corresponds to which device. But now that pps_idr defines userspace visibility instead of cdev_add(), we need to be sure the pps->dev refcount can't reach zero while userspace can still find it again. So, the idr_remove() call moves to pps_unregister_cdev(), and pps_idr now holds a reference to pps->dev. pps_core: source serial1 got cdev (251:1) <...> pps pps1: removed pps_core: unregistering pps1 pps_core: deallocating pps1

That seems like the simplest way to fix this, so I\u0027ve\nimplemented his suggestion, using __register_chrdev() with pps_idr\nbecoming the source of truth for which minor corresponds to which\ndevice.\n\nBut now that pps_idr defines userspace visibility instead of cdev_add(),\nwe need to be sure the pps-\u003edev refcount can\u0027t reach zero while\nuserspace can still find it again. So, the idr_remove() call moves to\npps_unregister_cdev(), and pps_idr now holds a reference to pps-\u003edev.\n\n    pps_core: source serial1 got cdev (251:1)\n    \u003c...\u003e\n    pps pps1: removed\n    pps_core: unregistering pps1\n    pps_core: deallocating pps1"

underflow; use-after-free.\\n    kernel BUG at lib/list_debug.c:62!\\n    Kernel panic - not syncing: Oops - BUG: Fatal exception\\n\\nThis happens because pps_device_destruct() frees the pps_device with the\\nembedded cdev immediately after calling cdev_del(), but, as the comment\\nabove cdev_del() notes, fops for previously opened cdevs are still\\ncallable even after cdev_del() returns. I think this bug has always\\nbeen there: I can\u0027t explain why it suddenly started happening every time\\nI reboot this particular board.\\n\\nIn commit d953e0e837e6 (\\\"pps: Fix a use-after free bug when\\nunregistering a source.\\\"), George Spelvin suggested removing the\\nembedded cdev. That seems like the simplest way to fix this, so I\u0027ve\\nimplemented his suggestion, using __register_chrdev() with pps_idr\\nbecoming the source of truth for which minor corresponds to which\\ndevice.\\n\\nBut now that pps_idr defines userspace visibility instead of cdev_add(),\\nwe need to be sure the pps-\u003edev refcount can\u0027t reach zero while\\nuserspace can still find it again. So, the idr_remove() call moves to\\npps_unregister_cdev(), and pps_idr now holds a reference to pps-\u003edev.\\n\\n    pps_core: source serial1 got cdev (251:1)\\n    \u003c...\u003e\\n    pps pps1: removed\\n    pps_core: unregistering pps1\\n    pps_core: deallocating pps1\"}], \"cpeApplicability\": [{\"nodes\": [{\"negate\": false, \"cpeMatch\": [{\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"5.4.291\", \"versionStartIncluding\": \"3.9\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"5.10.235\", \"versionStartIncluding\": \"3.9\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"5.15.179\", \"versionStartIncluding\": \"3.9\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.1.129\", \"versionStartIncluding\": \"3.9\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.6.76\", \"versionStartIncluding\": \"3.9\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.12.13\", \"versionStartIncluding\": \"3.9\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.13.2\", \"versionStartIncluding\": \"3.9\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.14\", \"versionStartIncluding\": \"3.9\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionStartIncluding\": \"3.2.40\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionStartIncluding\": \"3.4.87\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionStartIncluding\": \"3.8.1\"}], \"operator\": \"OR\"}]}], \"providerMetadata\": {\"orgId\": \"416baaa9-dc9f-4396-8d5f-8c081fb06d67\", \"shortName\": \"Linux\", \"dateUpdated\": \"2025-05-04T13:01:47.796Z\"}}}",
