| In the Linux kernel, the following vulnerability has been resolved:
wwan_hwsim: fix possible memory leak in wwan_hwsim_dev_new()
Inject fault while probing module, if device_register() fails,
but the refcount of kobject is not decreased to 0, the name
allocated in dev_set_name() is leaked. Fix this by calling
put_device(), so that name can be freed in callback function
kobject_cleanup().

wifi: brcmfmac: fix potential memory leak in brcmf_netdev_start_xmit()
The brcmf_netdev_start_xmit() returns NETDEV_TX_OK without freeing skb
in case of pskb_expand_head() fails, add dev_kfree_skb() to fix it.
Compile tested only. |

drivers: serial: jsm: fix some leaks in probe
This error path needs to unwind instead of just returning directly. |

kobject_add_internal failed for mtd-0 with -EEXIST, don't try to register
things with the same name in the same directory.
Error registering mtd class or bdi: -17
If init_mtdchar() fails in init_mtd(), mtd_bdi will not be unregistered,
as a result, we can't load the mtd module again, to fix this by calling
bdi_unregister(mtd_bdi) after out_procfs label. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/i915/bios: fix a memory leak in generate_lfp_data_ptrs
When (size != 0 || ptrs->lvds_ entries != 3), the program tries to
free() the ptrs. However, the ptrs is not created by calling kzmalloc(),
but is obtained by pointer offset operation.
This may lead to memory leaks or undefined behavior.
Fix this by replacing the arguments of kfree() with ptrs_block.
(cherry picked from commit 7674cd0b7d28b952151c3df26bbfa7e07eb2b4ec) |
| In the Linux kernel, the following vulnerability has been resolved:
PNP: fix name memory leak in pnp_alloc_dev()
After commit 1fa5ae857bb1 ("driver core: get rid of struct device's
bus_id string array"), the name of device is allocated dynamically,
move dev_set_name() after pnp_add_id() to avoid memory leak. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/radeon: Add the missed acpi_put_table() to fix memory leak
When the radeon driver reads the bios information from ACPI
table in radeon_acpi_vfct_bios(), it misses to call acpi_put_table()
to release the ACPI memory after the init, so add acpi_put_table()
properly to fix the memory leak.

drm/vkms: Fix memory leak in vkms_init()
A memory leak was reported after the vkms module install failed.

The reason is that the vkms_init() returns without checking the return
value of vkms_create(), and if the vkms_create() failed, the config
allocated at the beginning of vkms_init() is leaked.
vkms_init()
config = kmalloc(...) # config allocated
...
return vkms_create() # vkms_create failed and config is leaked
Fix this problem by checking return value of vkms_create() and free the
config if error happened. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: xhci-mtk: fix leakage of shared hcd when fail to set wakeup irq
Can not set the @shared_hcd to NULL before decrease the usage count
by usb_put_hcd(), this will cause the shared hcd not released. |
| In the Linux kernel, the following vulnerability has been resolved:
selinux: fix memleak in security_read_state_kernel()
In this function, it directly returns the result of __security_read_policy
without freeing the allocated memory in *data, cause memory leak issue,
so free the memory if __security_read_policy failed.
[PM: subject line tweak] |
| In the Linux kernel, the following vulnerability has been resolved:
ath11k: fix missing skb drop on htc_tx_completion error
On htc_tx_completion error the skb is not dropped. This is wrong since
the completion_handler logic expect the skb to be consumed anyway even
when an error is triggered. Not freeing the skb on error is a memory
leak since the skb won't be freed anywere else. Correctly free the
packet on eid >= ATH11K_HTC_EP_COUNT before returning.

| In the Linux kernel, the following vulnerability has been resolved:
drm/mcde: Fix refcount leak in mcde_dsi_bind
Every iteration of for_each_available_child_of_node() decrements
the reference counter of the previous node. There is no decrement
when break out from the loop and results in refcount leak.
Add missing of_node_put() to fix this. |
| In the Linux kernel, the following vulnerability has been resolved:
intel_th: Fix a resource leak in an error handling path
If an error occurs after calling 'pci_alloc_irq_vectors()',
'pci_free_irq_vectors()' must be called as already done in the remove
function. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/hfi1: fix potential memory leak in setup_base_ctxt()
setup_base_ctxt() allocates a memory chunk for uctxt->groups with
hfi1_alloc_ctxt_rcv_groups(). When init_user_ctxt() fails, uctxt->groups
is not released, which will lead to a memory leak.
We should release the uctxt->groups with hfi1_free_ctxt_rcv_groups()
when init_user_ctxt() fails. |
| In the Linux kernel, the following vulnerability has been resolved:
watchdog: sp5100_tco: Fix a memory leak of EFCH MMIO resource
Unlike release_mem_region(), a call to release_resource() does not
free the resource, so it has to be freed explicitly to avoid a memory
leak. |
| In the Linux kernel, the following vulnerability has been resolved:
cifs: Fix memory leak when using fscache
If we hit the 'index == next_cached' case, we leak a refcount on the
struct page. Fix this by using readahead_folio() which takes care of
the refcount for you. |
| In the Linux kernel, the following vulnerability has been resolved:
mm/damon/reclaim: fix potential memory leak in damon_reclaim_init()
damon_reclaim_init() allocates a memory chunk for ctx with
damon_new_ctx(). When damon_select_ops() fails, ctx is not released,
which will lead to a memory leak.
We should release the ctx with damon_destroy_ctx() when damon_select_ops()
fails to fix the memory leak. |

When cancel the deferred close work, we should also cleanup the struct
cifs_deferred_close. |
| In the Linux kernel, the following vulnerability has been resolved:
virtio_net: fix memory leak inside XPD_TX with mergeable
When we call xdp_convert_buff_to_frame() to get xdpf, if it returns
NULL, we should check if xdp_page was allocated by xdp_linearize_page().
If it is newly allocated, it should be freed here alone. Just like any
other "goto err_xdp". |
| In the Linux kernel, the following vulnerability has been resolved:
octeontx2-af: Fix mcam entry resource leak
The teardown sequence in FLR handler returns if no NIX LF
is attached to PF/VF because it indicates that graceful
shutdown of resources already happened. But there is a
chance of all allocated MCAM entries not being freed by
PF/VF. Hence free mcam entries even in case of detached LF. |
