  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: typec: ucsi: glink: fix use-after-free of ucsi on remove\n\nThe pmic_glink client is released by the devres cleanup, which runs\nafter pmic_glink_ucsi_remove() has returned, so its notification\ncallbacks can queue work until then. Work that runs after\nucsi_unregister() has been called touches freed state: it dereferences\nthe connector array that ucsi_unregister() freed, or registers and\nunregisters the instance a second time.\n\nDisable both work items with disable_work_sync() before unregistering,\nand unregister only if the instance is still registered.\n\nThis issue was found by an in-house static analysis tool.",
