| In the Linux kernel, the following vulnerability has been resolved:
arm64: acpi: Fix possible memory leak of ffh_ctxt
Allocated 'ffh_ctxt' memory leak is possible if the SMCCC version
and conduit checks fail and -EOPNOTSUPP is returned without freeing the
allocated memory.
Fix the same by moving the allocation after the SMCCC version and
conduit checks. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/client: Fix memory leak in drm_client_modeset_probe
When a new mode is set to modeset->mode, the previous mode should be freed.
This fixes the following kmemleak report:

| The Sparkle framework includes an XPC service Downloader.xpc, by default this service is private to the application its bundled with. A local unprivileged attacker can register this XPC service globally which will inherit TCC permissions of the application.
Lack of validation of connecting client allows the attacker to copy TCC-protected files to an arbitrary location. Access to other resources beyond granted-permissions requires user interaction with a system prompt asking for permission.
This issue was fixed in version 2.7.2 |

| In the Linux kernel, the following vulnerability has been resolved:
Drivers: vmbus: Check for channel allocation before looking up relids
relid2channel() assumes vmbus channel array to be allocated when called.
However, in cases such as kdump/kexec, not all relids will be reset by the host.
When the second kernel boots and if the guest receives a vmbus interrupt during
vmbus driver initialization before vmbus_connect() is called, before it finishes,
or if it fails, the vmbus interrupt service routine is called which in turn calls
relid2channel() and can cause a null pointer dereference.
Print a warning and error out in relid2channel() for a channel id that's invalid
in the second kernel. |
| In the Linux kernel, the following vulnerability has been resolved:
media: hi846: Fix memleak in hi846_init_controls()
hi846_init_controls doesn't clean the allocated ctrl_hdlr
in case there is a failure, which causes memleak. Add
v4l2_ctrl_handler_free to free the resource properly. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: iwl3945: Add missing check for create_singlethread_workqueue
Add the check for the return value of the create_singlethread_workqueue
in order to avoid NULL pointer dereference. |

fs/ntfs3: Fix null-ptr-deref on inode->i_op in ntfs_lookup()
Syzbot reported a null-ptr-deref bug:

ntfs3: loop0: Mark volume as dirty due to NTFS errors
general protection fault, probably for non-canonical address

If the MFT record of ntfs inode is not a base record, inode->i_op can be
NULL. And a null-ptr-deref may happen:
ntfs_lookup()
dir_search_u() # inode->i_op is set to NULL
d_splice_alias()
__d_add()
d_flags_for_inode() # inode->i_op->get_link null-ptr-deref
Fix this by adding a Check on inode->i_op before calling the
d_splice_alias() function. |

wifi: iwl4965: Add missing check for create_singlethread_workqueue()
Add the check for the return value of the create_singlethread_workqueue()
in order to avoid NULL pointer dereference. |
| In the Linux kernel, the following vulnerability has been resolved:
clk: imx: clk-imxrt1050: fix memory leak in imxrt1050_clocks_probe
Use devm_of_iomap() instead of of_iomap() to automatically
handle the unused ioremap region. If any error occurs, regions allocated by
kzalloc() will leak, but using devm_kzalloc() instead will automatically
free the memory using devm_kfree().
Also, fix error handling of hws by adding unregister_hws label, which
unregisters remaining hws when iomap failed. |
| In the Linux kernel, the following vulnerability has been resolved:
misc: vmw_balloon: fix memory leak with using debugfs_lookup()
When calling debugfs_lookup() the result must have dput() called on it,
otherwise the memory will leak over time. To make things simpler, just
call debugfs_lookup_and_remove() instead which handles all of the logic at
once. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: fsl_mqs: move of_node_put() to the correct location
of_node_put() should have been done directly after
mqs_priv->regmap = syscon_node_to_regmap(gpr_np);
otherwise it creates a reference leak on the success path.
To fix this, of_node_put() is moved to the correct location, and change
all the gotos to direct returns. |
| In the Linux kernel, the following vulnerability has been resolved:
ALSA: hda: fix a possible null-pointer dereference due to data race in snd_hdac_regmap_sync()
The variable codec->regmap is often protected by the lock
codec->regmap_lock when is accessed. However, it is accessed without
holding the lock when is accessed in snd_hdac_regmap_sync():
if (codec->regmap)
In my opinion, this may be a harmful race, because if codec->regmap is
set to NULL right after the condition is checked, a null-pointer
dereference can occur in the called function regcache_sync():
map->lock(map->lock_arg); --> Line 360 in drivers/base/regmap/regcache.c
To fix this possible null-pointer dereference caused by data race, the
mutex_lock coverage is extended to protect the if statement as well as the
function call to regcache_sync().
[ Note: the lack of the regmap_lock itself is harmless for the current
codec driver implementations, as snd_hdac_regmap_sync() is only for
PM runtime resume that is prohibited during the codec probe.
But the change makes the whole code more consistent, so it's merged

| The Blaze Demo Importer plugin for WordPress is vulnerable to unauthorized limited plugin install due to a missing capability check on the 'blaze_demo_importer_install_plugin' function in all versions up to, and including, 1.0.12. This makes it possible for authenticated attackers, with Subscriber-level access and above, to install and activate a limited number of specific plugins. The News Kit Elementor Addons plugin and a BlazeThemes theme must be installed and activated in order to exploit the vulnerability. |
