No affected components available
In the Linux kernel, the following vulnerability has been resolved: power: supply: pm8916_lbc: Fix use-after-free for extcon in IRQ handler Using the devm_ variant for requesting IRQ before the devm_ variant for allocating/registering the extcon handle, means that the extcon handle will be deallocated/unregistered before the interrupt handler (since devm_ naturally deallocates in reverse allocation order). This means that during removal, there is a race condition where an interrupt can fire just after the extcon handle has been freed, but just before the corresponding unregistration of the IRQ handler has run. This will lead to the IRQ handler calling extcon_set_state_sync() with a freed extcon handle. Which usually crashes the system or otherwise silently corrupts the memory... Fix this racy use-after-free by making sure the IRQ is requested after the registration of the extcon handle.
The vulnerability requires local access to the device to be exploited. It is easy for an attacker to exploit this vulnerability. An attacker needs basic access or low-level privileges. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data. There is a high impact on the availability of the system.
