{"id":"CVE-2026-64362","summary":"HID: lg-g15: cancel pending work on remove to fix a use-after-free","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nHID: lg-g15: cancel pending work on remove to fix a use-after-free\n\nlg_g15_data is allocated with devm and holds a work item. The report\nhandlers schedule that work straight from device input.\nlg_g15_event() and lg_g15_v2_event() do it on the backlight cycle key,\nand lg_g510_leds_event() does it too. The worker dereferences the\nlg_g15_data back through container_of.\n\nThe driver had no remove callback and never cancelled the work. So if a\nreport scheduled the work and the keyboard was then unplugged, devres\nfreed lg_g15_data while the work was still pending or running, and the\nworker touched freed memory. This is a use-after-free. It is reachable\nas a race on device unplug.\n\nAdd a remove callback that cancels the work before devres frees the\nstate. g15-\u003ework is only initialized for the models that schedule it\n(G15, G15 v2, G510). The G13 and Z-10 leave it zeroed, so guard the\ncancel on g15-\u003ework.func to avoid cancelling a work that was never set\nup. The g15 NULL test mirrors the one already in lg_g15_raw_event().","modified":"2026-07-27T04:03:21.448528629Z","published":"2026-07-25T08:50:18.008Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64362.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/33cd1a000daf929356aacf2b191d31714ff0615e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3b9a3919aac6977262f04d5365c0456877522a44"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4aef9676c26dff8723b56834951cfc6b618f0986"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4d0d51bc12d246accbfbb94de05d729c68c9b8fb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7705b4140d188ce22656f6e541ae7ef834c7e11a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8131f4226688c4be5f30874d167e44dab838eb09"},{"type":"WEB","url":"https://git.kernel.org/stable/c/acce9dee807f21184fff19ad17c8ed464247e7f7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/dfc6e61f83113cc18346b6988f07271c0063357d"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64362.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64362"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"97b741aba918c4143f4208d2421d08ff215c1b49"},{"fixed":"3b9a3919aac6977262f04d5365c0456877522a44"},{"fixed":"4aef9676c26dff8723b56834951cfc6b618f0986"},{"fixed":"acce9dee807f21184fff19ad17c8ed464247e7f7"},{"fixed":"33cd1a000daf929356aacf2b191d31714ff0615e"},{"fixed":"dfc6e61f83113cc18346b6988f07271c0063357d"},{"fixed":"4d0d51bc12d246accbfbb94de05d729c68c9b8fb"},{"fixed":"8131f4226688c4be5f30874d167e44dab838eb09"},{"fixed":"7705b4140d188ce22656f6e541ae7ef834c7e11a"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64362.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.5.0"},{"fixed":"5.10.261"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.212"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.178"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.145"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.96"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.39"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64362.json"}}],"schema_version":"1.7.5"}
