{"id":"CVE-2026-89468","summary":"power: supply: lp8788-charger: fix use-after-free on remove","details":"In the Linux kernel, the following vulnerability has been resolved:\n\npower: supply: lp8788-charger: fix use-after-free on remove\n\nlp8788_charger_remove() flushes charger_work before unregistering the\nIRQs. An IRQ thread can queue charger_work after flush_work() has\nreturned. The work can then run after devres frees pchg and dereference\nit in lp8788_charger_event().\n\nUnregister the IRQs first. free_irq() waits for any running threaded\nhandler, so no handler can queue more work afterwards. Then use\ncancel_work_sync() to cancel pending work or wait for running work to\nfinish.\n\nThis issue was found by an in-house static analysis tool.","modified":"2026-09-13T03:47:18.076282546Z","published":"2026-09-11T19:43:27.906Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89468.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/831c29a12d560f8a3225f43050b3fbb5dfd79c66"},{"type":"WEB","url":"https://git.kernel.org/stable/c/88d8eadfad5d9ff967e74090152940bcfa27df69"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b3aa1e9509e1b0a863353356d617fb45d1b6250a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b4eb6a056b441ba0caedfbfc42cec501acf12f67"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89468.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89468"},{"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":"98a2766493589c18c327ae3dad5243b53fcb5f70"},{"fixed":"88d8eadfad5d9ff967e74090152940bcfa27df69"},{"fixed":"b3aa1e9509e1b0a863353356d617fb45d1b6250a"},{"fixed":"b4eb6a056b441ba0caedfbfc42cec501acf12f67"},{"fixed":"831c29a12d560f8a3225f43050b3fbb5dfd79c66"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-89468.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.7.0"},{"fixed":"6.12.109"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.50"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-89468.json"}}],"schema_version":"1.9.0"}
