CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
ARM: OMAP2+: Fix refcount leak in omap3xxx_prm_late_init
of_find_matching_node() 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:
ARM: OMAP2+: Fix refcount leak in omapdss_init_of
omapdss_find_dss_of_node() calls of_find_compatible_node() to get device
node. 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() in later error path and normal path. |
| In the Linux kernel, the following vulnerability has been resolved:
ARM: bcm: Fix refcount leak in bcm_kona_smc_init
of_find_matching_node() 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:
mtd: maps: Fix refcount leak in ap_flash_init
of_find_matching_node() 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:
mtd: maps: Fix refcount leak in of_flash_probe_versatile
of_find_matching_node_and_match() 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:
wifi: libertas: Fix possible refcount leak in if_usb_probe()
usb_get_dev will be called before lbs_get_firmware_async which means that
usb_put_dev need to be called when lbs_get_firmware_async fails. |
| In the Linux kernel, the following vulnerability has been resolved:
rpmsg: qcom_smd: Fix refcount leak in qcom_smd_parse_edge
of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoc: audio-graph-card2: Fix refcount leak bug in __graph_get_type()
We should call of_node_put() for the reference before its replacement
as it returned by of_get_parent() which has increased the refcount.
Besides, we should also call of_node_put() before return. |
| In the Linux kernel, the following vulnerability has been resolved:
rpmsg: Fix possible refcount leak in rpmsg_register_device_override()
rpmsg_register_device_override need to call put_device to free vch when
driver_set_override fails.
Fix this by adding a put_device() to the error path. |
| In the Linux kernel, the following vulnerability has been resolved:
remoteproc: imx_rproc: Fix refcount leak in imx_rproc_addr_init
of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not needed anymore.
This function has two paths missing of_node_put(). |
| In the Linux kernel, the following vulnerability has been resolved:
remoteproc: k3-r5: Fix refcount leak in k3_r5_cluster_of_init
Every iteration of for_each_available_child_of_node() decrements
the reference count of the previous node.
When breaking early from a for_each_available_child_of_node() loop,
we need to explicitly call of_node_put() on the child node.
Add missing of_node_put() to avoid refcount leak. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: mediatek: mt8173-rt5650: Fix refcount leak in mt8173_rt5650_dev_probe
of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Fix refcount leak in some error paths. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: mediatek: mt8173: Fix refcount leak in mt8173_rt5650_rt5676_dev_probe
of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Fix missing of_node_put() in error paths. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: mt6797-mt6351: Fix refcount leak in mt6797_mt6351_dev_probe
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:
ASoC: cros_ec_codec: Fix refcount leak in cros_ec_codec_platform_probe
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:
HID: appletb-kbd: fix "appletb_backlight" backlight device reference counting
During appletb_kbd_probe, probe attempts to get the backlight device
by name. When this happens backlight_device_get_by_name looks for a
device in the backlight class which has name "appletb_backlight" and
upon finding a match it increments the reference count for the device
and returns it to the caller. However this reference is never released
leading to a reference leak.
Fix this by decrementing the backlight device reference count on removal
via put_device and on probe failure. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: aspeed-vhub: Fix refcount leak bug in ast_vhub_init_desc()
We should call of_node_put() for the reference returned by
of_get_child_by_name() which has increased the refcount. |
| In the Linux kernel, the following vulnerability has been resolved:
mmc: sdhci-of-esdhc: Fix refcount leak in esdhc_signal_voltage_switch
of_find_matching_node() 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.
of_node_put() checks null pointer. |
| In the Linux kernel, the following vulnerability has been resolved:
apparmor: fix reference count leak in aa_pivotroot()
The aa_pivotroot() function has a reference counting bug in a specific
path. When aa_replace_current_label() returns on success, the function
forgets to decrement the reference count of “target”, which is
increased earlier by build_pivotroot(), causing a reference leak.
Fix it by decreasing the refcount of “target” in that path. |
| In the Linux kernel, the following vulnerability has been resolved:
net/sched: fix netdevice reference leaks in attach_default_qdiscs()
In attach_default_qdiscs(), if a dev has multiple queues and queue 0 fails
to attach qdisc because there is no memory in attach_one_default_qdisc().
Then dev->qdisc will be noop_qdisc by default. But the other queues may be
able to successfully attach to default qdisc.
In this case, the fallback to noqueue process will be triggered. If the
original attached qdisc is not released and a new one is directly
attached, this will cause netdevice reference leaks.
The following is the bug log:
veth0: default qdisc (fq_codel) fail, fallback to noqueue
unregister_netdevice: waiting for veth0 to become free. Usage count = 32
leaked reference.

Fix this bug by clearing any non-noop qdiscs that may have been assigned
before trying to re-attach. |
