| In the Linux kernel, the following vulnerability has been resolved:
binder: fix UAF in binder_thread_release()
When a thread exits, binder_thread_release() walks its transaction stack
to clear the t->from and t->to_proc that correspond with the exiting
thread. However, a process dying in parallel might attempt to kfree some
of these transactions. And if one of them has no associated t->to_proc,
the t->to_proc->inner_lock will not be acquired.
This means that transaction accesses in binder_thread_release() after
t->to_proc has been cleared might race with binder_free_transaction()
and cause a use-after-free error as reported by KASAN:

==================================================================
In order to avoid this, make sure that binder_free_transaction() reads
the t->to_proc under the transaction lock. This will serialize the
transaction release with the accesses in binder_thread_release(). Plus,
it matches the documented locking rules for @to_proc. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btusb: fix use-after-free on registration failure
Make sure to release the sibling interfaces in case controller
registration fails to avoid use-after-free and double-free when they are
eventually disconnected.
This issue was reported by Sashiko while reviewing a fix for a wakeup
source leak in the btusb probe errors paths. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: temperature: tmp006: use devm_iio_trigger_register
tmp006_probe() allocates the DRDY trigger with devm_iio_trigger_alloc()
but registers it with plain iio_trigger_register(). The driver has no
.remove() callback, so on module unload the trigger stays in the global
trigger list while its memory is freed by devm, leaving a dangling
entry.
Switch to devm_iio_trigger_register() so the registration is undone in
the same devm scope as the allocation. |
