"value": "In the Linux kernel, the following vulnerability has been resolved:\n\npower: supply: pm8916_lbc: Fix use-after-free for extcon in IRQ handler\n\nUsing the `devm_` variant for requesting IRQ _before_ the `devm_`\nvariant for allocating/registering the `extcon` handle, means that the\n`extcon` handle will be deallocated/unregistered _before_ the interrupt\nhandler (since `devm_` naturally deallocates in reverse allocation\norder). This means that during removal, there is a race condition where\nan interrupt can fire just _after_ the `extcon` handle has been\nfreed, *but* just _before_ the corresponding unregistration of the IRQ\nhandler has run.\n\nThis will lead to the IRQ handler calling `extcon_set_state_sync()` with\na freed `extcon` handle. Which usually crashes the system or otherwise\nsilently corrupts the memory...\n\nFix this racy use-after-free by making sure the IRQ is requested _after_\nthe registration of the `extcon` handle."
