The opt->iocharset is freed inside the isofs_fill_super function,
But there may be situations where it's not possible to
enter this function.
For example, in the get_tree_bdev_flags function,when
encountering the situation where "Can't mount, would change RO state,"
In such a case, isofs_fill_super will not have the opportunity
to be called,which means that opt->iocharset will not have the chance
to be freed,ultimately leading to a memory leak.
Let's move the memory freeing of opt->iocharset into
isofs_free_fc function. |
| In the Linux kernel, the following vulnerability has been resolved:
firmware_loader: Fix possible resource leak in fw_log_firmware_info()
The alg instance should be released under the exception path, otherwise
there may be resource leak here.
To mitigate this, free the alg instance with crypto_free_shash when kmalloc
fails. |
| In the Linux kernel, the following vulnerability has been resolved:
dmaengine: tegra: Fix memory leak in terminate_all()
Terminate vdesc when terminating an ongoing transfer.
This will ensure that the vdesc is present in the desc_terminated list
The descriptor will be freed later in desc_free_list().
This fixes the memory leaks which can happen when terminating an
ongoing transfer. |
| In the Linux kernel, the following vulnerability has been resolved:
HV: hv_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:
kernel/irq/irqdomain.c: 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:
irqchip/gic/realview: Fix refcount leak in realview_gic_of_init
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:
irqchip/apple-aic: Fix refcount leak in aic_of_ic_init
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. |
| In the Linux kernel, the following vulnerability has been resolved:
irqchip/apple-aic: Fix refcount leak in build_fiq_affinity
of_find_node_by_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:
irqchip/gic-v3: Fix error handling in gic_populate_ppi_partitions
of_get_child_by_name() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
When kcalloc fails, it missing of_node_put() and results in refcount
leak. Fix this by goto out_put_node label. |
| In the Linux kernel, the following vulnerability has been resolved:
irqchip/gic-v3: Fix refcount leak in gic_populate_ppi_partitions
of_find_node_by_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:
usb: gadget: lpc32xx_udc: Fix refcount leak in lpc32xx_udc_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.
of_node_put() will check NULL pointer. |
| In the Linux kernel, the following vulnerability has been resolved:
9p: fix fid refcount leak in v9fs_vfs_atomic_open_dotl
We need to release directory fid if we fail halfway through open
This fixes fid leaking with xfstests generic 531 |
| In the Linux kernel, the following vulnerability has been resolved:
drm/msm/mdp4: Fix refcount leak in mdp4_modeset_init_intf
of_graph_get_remote_node() returns remote device 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:
iio: adc: aspeed: Fix refcount leak in aspeed_adc_set_trim_data
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:
iio: adc: adi-axi-adc: Fix refcount leak in adi_axi_adc_attach_client
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:
ARM: exynos: Fix refcount leak in exynos_map_pmu
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:
soc: bcm: brcmstb: pm: pm-arm: Fix refcount leak in brcmstb_pm_probe
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 brcmstb_init_sram, it pass dn to of_address_to_resource(),
of_address_to_resource() will call of_find_device_by_node() to take
reference, so we should release the reference returned by
of_find_matching_node(). |
| In the Linux kernel, the following vulnerability has been resolved:
ARM: cns3xxx: Fix refcount leak in cns3xxx_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:
memory: samsung: exynos5422-dmc: Fix refcount leak in of_get_dram_timings
of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
This function doesn't call of_node_put() in some error paths.
To unify the structure, Add put_node label and goto it on errors. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/cm: Fix memory leak in ib_cm_insert_listen
cm_alloc_id_priv() allocates resource for the cm_id_priv. When
cm_init_listen() fails it doesn't free it, leading to memory leak.
Add the missing error unwind. |
