{"id":"AZL-93776","summary":"CVE-2026-64362 affecting package kernel for versions less than 6.6.145.2-1","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":"2026-08-28T17:48:12.954153724Z","published":"2026-07-25T10:17:18Z","upstream":["CVE-2026-64362"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64362"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.145.2-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-93776.json"}}],"schema_version":"1.9.0"}
