| In the Linux kernel, the following vulnerability has been resolved:
binder: fix UAF in binder_netlink_report()
Oneway transactions sent to frozen targets via binder_proc_transaction()
return a BR_TRANSACTION_PENDING_FROZEN error but they are still treated
as successful since the target is expected to thaw at some point. It is
then not safe to access 't' after BR_TRANSACTION_PENDING_FROZEN errors
as the transaction could have been consumed by the now thawed target.
This is the case for binder_netlink_report() which derreferences 't'
after a pending frozen error, as pointed out by the following KASAN
report:

Instead, make a transaction copy so the data can be safely accessed by
binder_netlink_report() after a pending frozen error. While here, add a
comment about not using t->buffer in binder_netlink_report(). |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: mld: cancel mlo_scan_start_wk
mlo_scan_start_wk is not canceled on disconnection. In fact, it is not
canceled anywhere except in the restart cleanup, where we don't really
have to.
This can cause an init-after-queue issue: if, for example, the work was
queued and then drv_change_interface got executed.
This can also cause use-after-free: if the work is executed after the
vif is freed. |
| In the Linux kernel, the following vulnerability has been resolved:
linkwatch: use __dev_put() in callers to prevent UAF
After linkwatch_do_dev() calls __dev_put() to release the linkwatch
reference, the device refcount may drop to 1. At this point,
netdev_run_todo() can proceed (since linkwatch_sync_dev() sees an
empty list and returns without blocking), wait for the refcount to
become 1 via netdev_wait_allrefs_any(), and then free the device
via kobject_put().
This creates a use-after-free when __linkwatch_run_queue() tries to
call netdev_unlock_ops() on the already-freed device.
Note that adding netdev_lock_ops()/netdev_unlock_ops() pair in
netdev_run_todo() before kobject_put() would not work, because
netdev_lock_ops() is conditional - it only locks when
netdev_need_ops_lock() returns true. If the device doesn't require
ops_lock, linkwatch won't hold any lock, and netdev_run_todo()
acquiring the lock won't provide synchronization.
Fix this by moving __dev_put() from linkwatch_do_dev() to its
callers. The device reference logically pairs with de-listing the
device, so it's reasonable for the caller that did the de-listing
to release it. This allows placing __dev_put() after all device
accesses are complete, preventing UAF.
The bug can be reproduced by adding mdelay(2000) after
linkwatch_do_dev() in __linkwatch_run_queue(), then running:
ip tuntap add mode tun name tun_test
ip link set tun_test up
ip link set tun_test carrier off
ip link set tun_test carrier on
sleep 0.5
ip tuntap del mode tun name tun_test
