| In the Linux kernel, the following vulnerability has been resolved:
io_uring: fix task_work add use-after-free with SQPOLL
For SQPOLL, the sqpoll thread runs task_work off its own list and
doesn't need to be told about it, so it can pop and complete a request
as soon as mpscq_push() has published it. If that was the last request
holding the ring alive, io_ring_exit_work() then frees the ctx, stops
the thread, and with it the tctx, while io_req_normal_work_add() is
still looking at both after the push:

as well before freeing the ctx. |
| In the Linux kernel, the following vulnerability has been resolved:
binderfs: fix UAF write in binder_add_device
binderfs_binder_device_create() publishes the new dentry with
d_make_persistent() and then calls simple_done_creating(), which drops
the parent directory lock and the creator's dentry reference. It then
calls binder_add_device() to register the device in the global
binder_devices list.
After simple_done_creating() releases the parent directory lock, a
concurrent unlinkat() can remove the new device entry. Dropping the
creator's dentry reference can then trigger binderfs_evict_inode(),
freeing the device. binder_add_device() later accesses the freed
object, causing UAF write.

rtc: ac100: Fix clock provider use-after-free on probe failure
ac100_rtc_register_clks() registers the RTC-32k clock with
clk_hw_register_fixed_rate() and the clock provider with
of_clk_add_hw_provider(). Neither is device managed, and both are
released only from ac100_rtc_remove(). The driver core does not call
remove() when probe() fails: really_probe() reaches probe_failed below
the device_remove() call and goes straight to releasing the device's
managed resources.
ac100_rtc_probe() ends with
return devm_rtc_register_device(chip->rtc);
so if that fails after the clocks have been registered, the provider is
left on the global of_clk_providers list holding chip->clk_data, which
was allocated with devm_kzalloc() and is freed while probe() unwinds. A
later lookup on this device tree node then reads freed memory in
of_clk_hw_onecell_get(). Consumers that do exactly that exist in tree:
the wifi power sequence nodes on sun8i-a83t-bananapi-m3 and
sun8i-a83t-cubietruck-plus take <&ac100_rtc 1>, and the sun9i-a80 boards
route osc32k through <&ac100_rtc 0>. The window is narrow, as
devm_rtc_register_device() can only fail with -ENOMEM here, but the
provider is left dangling whenever it does.
The RTC-32k clock is leaked on the same path. Since clk_core_lookup()
searches a global list that is not scoped per device, __clk_register()
rejects the duplicate name with -EEXIST, so the leak also makes a later
probe of the same device fail.
The error path that returns -EINVAL when the ADDA 4M parent clock cannot
be found leaks the RTC-32k clock in the same way. No provider has been
registered at that point, so that one is a leak rather than a
use-after-free.
Register both with devm_clk_hw_register_fixed_rate() and
devm_of_clk_add_hw_provider() so that they are released whenever the
device goes away, on a failed probe as well as on unbind. Devres
releases in reverse order of acquisition, so the provider is removed
before chip->clk_data is freed, and the clkout children are now
unregistered before their parent rather than after it.
ac100_rtc_unregister_clks() and the remove callback then have nothing
left to do and are removed. |

nvme: fix command effects log lifetime for multipath heads
KASAN reported a use-after-free when an I/O passthrough command was sent
through a multipath namespace head after the controller path that first
created the head had been removed:

Move the log cache to the subsystem, with one entry per command set. Both
controllers and namespace heads hold subsystem references, keeping their
log pointers valid until subsystem release. |

| In the Linux kernel, the following vulnerability has been resolved:
rust_binder: cancel deferred work items in thread exit
If there are deferred work items on the thread todo list, then they are
not cleaned up in the Thread::release() method. Thus, update the code to
clean up the work items even if they are deferred.
This can happen if the thread dies while it has an active outgoing
transaction. |
| In the Linux kernel, the following vulnerability has been resolved:
ipe: protect the dm-verity root hash with RCU
ipe_bdev_setintegrity() frees the old root hash when dm-verity publishes
a new one on ->preresume, while policy evaluation can still be
dereferencing it.
Protect the root hash with RCU. The evaluation path already runs under
rcu_read_lock().
[FW: remove model name according to latest guideline] |
| In the Linux kernel, the following vulnerability has been resolved:
drm/i915: fix incorrect RCU teardown order
i915_gem_busy_ioctl uses dma_resv_for_each_fence_unlocked() to iterate
over the fences in an GEM object without holding a reference but only
the RCU read side lock.
What can happen here is that the GEM object is destroyed concurrently
while i915_gem_busy_ioctl is still running. This won't free the GEM
objects memory, but still drops all the dma_fence references.
Now when dma_resv_for_each_fence_unlocked() sees a destroyed dma_fence it
assumes that a new fence list was installed and re-starts the loop.
But in the case of a destroyed GEM object a new fence list is never
installed, only the old one freed and therefore the iteration never
finishes resulting in an endless loop.
The solution is to drop the fence references only after the RCU grace
period.
The fixes tag is not necessary the patch introducing the problem, but the
one making it so worse that we need to address it.
This problem was pointed out by Sashiko-bot.
(cherry picked from commit 5113479556025093bf8133bb2dcaa33be2d50921) |
