| In the Linux kernel, the following vulnerability has been resolved:
rpmsg: glink: Add check for kstrdup
Add check for the return value of kstrdup() and return the error
if it fails in order to avoid NULL pointer dereference. |
| In the Linux kernel, the following vulnerability has been resolved:
PCI/DOE: Fix memory leak with CONFIG_DEBUG_OBJECTS=y
After a pci_doe_task completes, its work_struct needs to be destroyed
to avoid a memory leak with CONFIG_DEBUG_OBJECTS=y. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/core: Fix GID entry ref leak when create_ah fails
If AH create request fails, release sgid_attr to avoid GID entry
referrence leak reported while releasing GID table |
| In the Linux kernel, the following vulnerability has been resolved:
binder: fix memory leak in binder_init()
In binder_init(), the destruction of binder_alloc_shrinker_init() is not
performed in the wrong path, which will cause memory leaks. So this commit
introduces binder_alloc_shrinker_exit() and calls it in the wrong path to
fix that. |
| In the Linux kernel, the following vulnerability has been resolved:
virtio_vdpa: build affinity masks conditionally
We try to build affinity mask via create_affinity_masks()
unconditionally which may lead several issues:
- the affinity mask is not used for parent without affinity support
(only VDUSE support the affinity now)
- the logic of create_affinity_masks() might not work for devices
other than block. For example it's not rare in the networking device
where the number of queues could exceed the number of CPUs. Such
case breaks the current affinity logic which is based on
group_cpus_evenly() who assumes the number of CPUs are not less than
the number of groups. This can trigger a warning[1]:
if (ret >= 0)
WARN_ON(nr_present + nr_others < numgrps);
Fixing this by only build the affinity masks only when
- Driver passes affinity descriptor, driver like virtio-blk can make
sure to limit the number of queues when it exceeds the number of CPUs
- Parent support affinity setting config ops
This help to avoid the warning. More optimizations could be done on
top.

| In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Devcom, fix error flow in mlx5_devcom_register_device
In case devcom allocation is failed, mlx5 is always freeing the priv.
However, this priv might have been allocated by a different thread,
and freeing it might lead to use-after-free bugs.
Fix it by freeing the priv only in case it was allocated by the
running thread. |
| In the Linux kernel, the following vulnerability has been resolved:
ext4: set goal start correctly in ext4_mb_normalize_request
We need to set ac_g_ex to notify the goal start used in
ext4_mb_find_by_goal. Set ac_g_ex instead of ac_f_ex in
ext4_mb_normalize_request.
Besides we should assure goal start is in range [first_data_block,
blocks_count) as ext4_mb_initialize_context does.
[ Added a check to make sure size is less than ar->pright; otherwise
we could end up passing an underflowed value of ar->pright - size to
ext4_get_group_no_and_offset(), which will trigger a BUG_ON later on.

| In the Linux kernel, the following vulnerability has been resolved:
iommufd: Make sure to zero vfio_iommu_type1_info before copying to user
Missed a zero initialization here. Most of the struct is filled with
a copy_from_user(), however minsz for that copy is smaller than the
actual struct by 8 bytes, thus we don't fill the padding. |
| In the Linux kernel, the following vulnerability has been resolved:
ice: prevent NULL pointer deref during reload
Calling ethtool during reload can lead to call trace, because VSI isn't
configured for some time, but netdev is alive.
To fix it add rtnl lock for VSI deconfig and config. Set ::num_q_vectors
to 0 after freeing and add a check for ::tx/rx_rings in ring related
ethtool ops.
Add proper unroll of filters in ice_start_eth().
Reproduction:
$watch -n 0.1 -d 'ethtool -g enp24s0f0np0'
$devlink dev reload pci/0000:18:00.0 action driver_reinit

| In the Linux kernel, the following vulnerability has been resolved:
io_uring: fix memory leak when removing provided buffers
When removing provided buffers, io_buffer structs are not being disposed
of, leading to a memory leak. They can't be freed individually, because
they are allocated in page-sized groups. They need to be added to some
free list instead, such as io_buffers_cache. All callers already hold
the lock protecting it, apart from when destroying buffers, so had to
extend the lock there. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/rockchip: dw_hdmi: cleanup drm encoder during unbind
This fixes a use-after-free crash during rmmod.
The DRM encoder is embedded inside the larger rockchip_hdmi,
which is allocated with the component. The component memory
gets freed before the main drm device is destroyed. Fix it
by running encoder cleanup before tearing down its container.
[moved encoder cleanup above clk_disable, similar to bind-error-path] |
| In the Linux kernel, the following vulnerability has been resolved:
xfrm: also call xfrm_state_delete_tunnel at destroy time for states that were never added
In commit b441cf3f8c4b ("xfrm: delete x->tunnel as we delete x"), I
missed the case where state creation fails between full
initialization (->init_state has been called) and being inserted on
the lists.
In this situation, ->init_state has been called, so for IPcomp
tunnels, the fallback tunnel has been created and added onto the
lists, but the user state never gets added, because we fail before
that. The user state doesn't go through __xfrm_state_delete, so we
don't call xfrm_state_delete_tunnel for those states, and we end up
leaking the FB tunnel.
There are several codepaths affected by this: the add/update paths, in
both net/key and xfrm, and the migrate code (xfrm_migrate,
xfrm_state_migrate). A "proper" rollback of the init_state work would
probably be doable in the add/update code, but for migrate it gets
more complicated as multiple states may be involved.
At some point, the new (not-inserted) state will be destroyed, so call
xfrm_state_delete_tunnel during xfrm_state_gc_destroy. Most states
will have their fallback tunnel cleaned up during __xfrm_state_delete,
which solves the issue that b441cf3f8c4b (and other patches before it)
aimed at. All states (including FB tunnels) will be removed from the
lists once xfrm_state_fini has called flush_work(&xfrm_state_gc_work). |
| In the Linux kernel, the following vulnerability has been resolved:
kheaders: Use array declaration instead of char
Under CONFIG_FORTIFY_SOURCE, memcpy() will check the size of destination
and source buffers. Defining kernel_headers_data as "char" would trip
this check. Since these addresses are treated as byte arrays, define
them as arrays (as done everywhere else).
This was seen with:

The reproducer was a simple script:
#!/bin/sh
for i in `seq 1 5`; do
modprobe -rv igb
modprobe -v igb max_vfs=1
sleep 1
modprobe -rv igb
done
It turned out that this could only be reproduce on 82580 (quad and
dual-port), but not on 82576, i350 and i210. Further debugging showed
that igb_enable_sriov()'s call to pci_enable_sriov() is failing, because
dev->is_physfn is 0 on 82580.
Prior to commit 50f303496d92 ("igb: Enable SR-IOV after reinit"),
igb_enable_sriov() jumped into the "err_out" cleanup branch. After this
commit it only returned the error code.
So the cleanup didn't take place, and the incorrect VF setup in the
igb_adapter structure fooled the igb driver into assuming that VFs have
been set up where no VF actually existed.
Fix this problem by cleaning up again if pci_enable_sriov() fails. |

| In the Linux kernel, the following vulnerability has been resolved:
ASoC: mediatek: common: Fix refcount leak in parse_dai_link_info
Add missing of_node_put()s before the returns to balance
of_node_get()s and of_node_put()s, which may get unbalanced
in case the for loop 'for_each_available_child_of_node' returns
early. |
| In the Linux kernel, the following vulnerability has been resolved:
btrfs: zoned: skip splitting and logical rewriting on pre-alloc write
When doing a relocation, there is a chance that at the time of
btrfs_reloc_clone_csums(), there is no checksum for the corresponding
region.
In this case, btrfs_finish_ordered_zoned()'s sum points to an invalid item
and so ordered_extent's logical is set to some invalid value. Then,
btrfs_lookup_block_group() in btrfs_zone_finish_endio() failed to find a
block group and will hit an assert or a null pointer dereference as
following.
This can be reprodcued by running btrfs/028 several times (e.g, 4 to 16
times) with a null_blk setup. The device's zone size and capacity is set to
32 MB and the storage size is set to 5 GB on my setup.

On the zoned mode, writing to pre-allocated region means data relocation
write. Such write always uses WRITE command so there is no need of splitting
and rewriting logical address. Thus, we can just skip the function for the
case. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/client: Fix memory leak in drm_client_target_cloned
dmt_mode is allocated and never freed in this function.
It was found with the ast driver, but most drivers using generic fbdev
setup are probably affected.
This fixes the following kmemleak report:
