If hidinput_connect()\nfails -- for instance because input_register_device() returns an error --\nit unwinds through hidinput_disconnect(), which frees every input_dev it\ncreated, including the one cached in msc->input.\n\nThe failure does not abort the probe. hid_connect() only skips the claim:\n\n\tif ((connect_mask & HID_CONNECT_HIDINPUT) && !hidinput_connect(hdev,\n\t\t\t\tconnect_mask & HID_CONNECT_HIDINPUT_FORCE))\n\t\thdev->claimed |= HID_CLAIMED_INPUT;\n\nand the \"device has no listeners\" bailout below it does not fire for this\ndriver, which sets ->raw_event; on the USB Magic Mouse 2 / Magic Trackpad\n2 paths hidraw and hiddev are claimed as well. hid_hw_start() therefore\nreturns 0 and magicmouse_probe() continues with msc->input pointing at\nfreed memory. Being non-NULL, it passes the \"input not registered\" check\nin probe and the NULL checks in ->raw_event and ->event, so the next\ninput report dereferences freed memory.\n\nClear msc->input when the HID core did not claim an input device, so the\nexisting NULL checks cover this case as well."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/hid/hid-magicmouse.c"],"versions":[{"version":"f1a9a149abc86903e81dd1b2e720f3f89874384b","lessThan":"c3597923932bb90d4fc2186aef552f6677175e4a","status":"affected","versionType":"git"},{"version":"f1a9a149abc86903e81dd1b2e720f3f89874384b","lessThan":"e0c224c93d10ee38854fdf24c815108aedd3dcb3","status":"affected","versionType":"git"},{"version":"f1a9a149abc86903e81dd1b2e720f3f89874384b","lessThan":"403cc9bd6ccb9fbe68d501c3236e5a6dd5504e14","status":"affected","versionType":"git"},{"version":"f1a9a149abc86903e81dd1b2e720f3f89874384b","lessThan":"3d7a7bac4c75f25b2513505a0ac5ba909588ed2b","status":"affected","versionType":"git"},{"version":"f1a9a149abc86903e81dd1b2e720f3f89874384b","lessThan":"9bdf8c7bfd79f1090e61d28f969b32880fd77bb3","status":"affected","versionType":"git"},{"version":"f1a9a149abc86903e81dd1b2e720f3f89874384b","lessThan":"15b60ade825c8ce9ec560048a4ae3747e4572be3","status":"affected","versionType":"git"},{"version":"f1a9a149abc86903e81dd1b2e720f3f89874384b","lessThan":"0bf253e9ac994cb5329bc87b00bb4eeca9136791","status":"affected","versionType":"git"},{"version":"f1a9a149abc86903e81dd1b2e720f3f89874384b","lessThan":"2ef16934e069d5f771e989d6ee5c3ece5042f3cd","status":"affected","versionType":"git"},{"version":"f1a9a149abc86903e81dd1b2e720f3f89874384b","lessThan":"0af3b89705688af01aa06025b84fa7a1e06ba6cc","status":"affected","versionType":"git"},{"version":"0e55072e7c63a6569cab1447e9025d160abd9dd9","status":"affected","versionType":"git"},{"version":"3.8.7","lessThan":"3.9","status":"affected","versionType":"semver"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/hid/hid-magicmouse.c"],"versions":[{"version":"3.9","status":"affected"},{"version":"0","lessThan":"3.9","status":"unaffected","versionType":"semver"},{"version":"5.10.269","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.218","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.185","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.154","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.106","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.47","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.1.11","lessThanOrEqual":"7.1.*","status":"unaffected","versionType":"semver"},{"version":"7.2.1","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3-rc1","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.9","versionEndExcluding":"5.10.269"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.9","versionEndExcluding":"5.15.218"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.9","versionEndExcluding":"6.1.185"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.9","versionEndExcluding":"6.6.154"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.9","versionEndExcluding":"6.12.106"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.9","versionEndExcluding":"6.18.47"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.9","versionEndExcluding":"7.1.11"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.9","versionEndExcluding":"7.2.1"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.9","versionEndExcluding":"7.3-rc1"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.8.7"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/c3597923932bb90d4fc2186aef552f6677175e4a"},{"url":"https://git.kernel.org/stable/c/e0c224c93d10ee38854fdf24c815108aedd3dcb3"},{"url":"https://git.kernel.org/stable/c/403cc9bd6ccb9fbe68d501c3236e5a6dd5504e14"},{"url":"https://git.kernel.org/stable/c/3d7a7bac4c75f25b2513505a0ac5ba909588ed2b"},{"url":"https://git.kernel.org/stable/c/9bdf8c7bfd79f1090e61d28f969b32880fd77bb3"},{"url":"https://git.kernel.org/stable/c/15b60ade825c8ce9ec560048a4ae3747e4572be3"},{"url":"https://git.kernel.org/stable/c/0bf253e9ac994cb5329bc87b00bb4eeca9136791"},{"url":"https://git.kernel.org/stable/c/2ef16934
