| In the Linux kernel, the following vulnerability has been resolved:
regulator: pfuze100: Fix refcount leak in pfuze_parse_regulators_dt
of_node_get() returns a node with refcount incremented.
Calling of_node_put() to drop the reference when not needed anymore. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: ti: j721e-evm: Fix refcount leak in j721e_soc_probe_*
of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not needed anymore.
Add missing of_node_put() to avoid refcount leak. |
| In the Linux kernel, the following vulnerability has been resolved:
thermal/core: Fix memory leak in __thermal_cooling_device_register()
I got memory leak as follows when doing fault injection test:

If device_register() fails, thermal_cooling_device_destroy_sysfs() need be called
to free the memory allocated in thermal_cooling_device_setup_sysfs(). |
| In the Linux kernel, the following vulnerability has been resolved:
drm: msm: fix possible memory leak in mdp5_crtc_cursor_set()
drm_gem_object_lookup will call drm_gem_object_get inside. So cursor_bo
needs to be put when msm_gem_get_and_pin_iova fails. |
| In the Linux kernel, the following vulnerability has been resolved:
regulator: scmi: Fix refcount leak in scmi_regulator_probe
of_find_node_by_name() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/msm/a6xx: Fix refcount leak in a6xx_gpu_init
of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
a6xx_gmu_init() passes the node to of_find_device_by_node()
and of_dma_configure(), of_find_device_by_node() will takes its
reference, of_dma_configure() doesn't need the node after usage.
Add missing of_node_put() to avoid refcount leak. |
| In the Linux kernel, the following vulnerability has been resolved:
amt: fix memory leak for advertisement message
When a gateway receives an advertisement message, it extracts relay
information and then it should be freed.
But the advertisement handler doesn't free it.
So, memory leak would occur. |
| In the Linux kernel, the following vulnerability has been resolved:
ARM: versatile: Add missing of_node_put in dcscb_init
The device_node pointer is returned by of_find_compatible_node
with refcount incremented. We should use of_node_put() to avoid
the refcount leak. |
| In the Linux kernel, the following vulnerability has been resolved:
ARM: hisi: Add missing of_node_put after of_find_compatible_node
of_find_compatible_node will increment the refcount of the returned
device_node. Calling of_node_put() to avoid the refcount leak |
| In the Linux kernel, the following vulnerability has been resolved:
drivers/base/node.c: fix compaction sysfs file leak
Compaction sysfs file is created via compaction_register_node in
register_node. But we forgot to remove it in unregister_node. Thus
compaction sysfs file is leaked. Using compaction_unregister_node to fix
this issue. |
| In the Linux kernel, the following vulnerability has been resolved:
powerpc/fsl_rio: Fix refcount leak in fsl_rio_setup
of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak. |
| In the Linux kernel, the following vulnerability has been resolved:
powerpc/xive: Fix refcount leak in xive_spapr_init
of_find_compatible_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak. |
| In the Linux kernel, the following vulnerability has been resolved:
ext4: fix memory leak in parse_apply_sb_mount_options()
If processing the on-disk mount options fails after any memory was
allocated in the ext4_fs_context, e.g. s_qf_names, then this memory is
leaked. Fix this by calling ext4_fc_free() instead of kfree() directly.
Reproducer:
mkfs.ext4 -F /dev/vdc
tune2fs /dev/vdc -E mount_opts=usrjquota=file
echo clear > /sys/kernel/debug/kmemleak
mount /dev/vdc /vdc
echo scan > /sys/kernel/debug/kmemleak
sleep 5
echo scan > /sys/kernel/debug/kmemleak
cat /sys/kernel/debug/kmemleak |
| In the Linux kernel, the following vulnerability has been resolved:
lib/string_helpers: fix not adding strarray to device's resource list
Add allocated strarray to device's resource list. This is a must to
automatically release strarray when the device disappears.
Without this fix we have a memory leak in the few drivers which use
devm_kasprintf_strarray(). |
| In the Linux kernel, the following vulnerability has been resolved:
jffs2: fix memory leak in jffs2_do_fill_super
If jffs2_iget() or d_make_root() in jffs2_do_fill_super() returns
an error, we can observe the following kmemleak report:

--------------------------------------------
This is because the resources allocated in jffs2_sum_init() are not
released. Call jffs2_sum_exit() to release these resources to solve
the problem. |
| In the Linux kernel, the following vulnerability has been resolved:
firmware: dmi-sysfs: Fix memory leak in dmi_sysfs_register_handle
kobject_init_and_add() takes reference even when it fails.
According to the doc of kobject_init_and_add()
If this function returns an error, kobject_put() must be called to
properly clean up the memory associated with the object.
Fix this issue by calling kobject_put(). |
| In the Linux kernel, the following vulnerability has been resolved:
amt: fix possible memory leak in amt_rcv()
If an amt receives packets and it finds socket.
If it can't find a socket, it should free a received skb.
But it doesn't.
So, a memory leak would possibly occur. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix reference count leak in smb_check_perm_dacl()
The issue happens in a specific path in smb_check_perm_dacl(). When
"id" and "uid" have the same value, the function simply jumps out of
the loop without decrementing the reference count of the object
"posix_acls", which is increased by get_acl() earlier. This may
result in memory leaks.
Fix it by decreasing the reference count of "posix_acls" before
jumping to label "check_access_bits". |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: memleak flow rule from commit path
Abort path release flow rule object, however, commit path does not.
Update code to destroy these objects before releasing the transaction. |
| In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: bgmac: Fix refcount leak in bcma_mdio_mii_register
of_get_child_by_name() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak. |
