| In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: fix leak in ath11k_service_ready_ext_event()
Currently, during ath11k_service_ready_ext_event() processing,
svc_rdy_ext.mac_phy_caps can be allocated during TLV parsing. This is a
temporary allocation that is freed on the success path, but not on the
error path. If parsing succeeds far enough to allocate mac_phy_caps and
then fails on a later TLV, the allocation leaks. So free the allocation
on the error path.
Compile tested only. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt792x: Fix memory leak in SDIO TX path
When tx_prepare_skb() returns an error in the SDIO TX path, the
skb is not freed, leading to a memory leak. This can occur when
zero-length frames (such as WNM NULL frames) are dropped to prevent
potential hardware TX hangs.
Fix this by properly releasing the skb with ieee80211_tx_status_ext()
when tx_prepare_skb() fails. |
| In the Linux kernel, the following vulnerability has been resolved:
iommu/tegra241-cmdqv: Fix VINTF0 leak on the init-failure path
tegra241_cmdqv_init_structures() allocates VINTF0 with kzalloc_obj(), inits
it, and preallocates its logical VCMDQs. Two of its error paths leak.
When tegra241_cmdqv_init_vintf() fails it returns before VINTF0 reaches the
cmdqv->vintfs[] array, so the devres unwind on probe failure cannot reach
it; free it directly there.
A later VCMDQ preallocation failure instead leaves VINTF0 published, and so
this time the unwind does reach tegra241_cmdqv_remove_vintf(), which then
frees it from vintf->hyp_own. But tegra241_vintf_hw_init() sets that flag
only afterward, from a HW read-back, so the still-uninited VINTF0 reads as
guest-owned and leaks, with mutex_destroy() and ida_destroy() run on fields
it never set up.
Decide ownership from vintf->idx instead, the index assigned when its id is
allocated: idx 0 is the kernel-owned VINTF0, while idx >= 1 marks a guest
VINTF. So the in-kernel free decision in tegra241_cmdqv_remove_vintf() and
tegra241_vintf_free_lvcmdq() now keys on idx too, and hyp_own stays a pure
HW-readback state. |
| In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix infinite loop in nilfs_clean_segments()
syzbot reported a hung task in nilfs_transaction_begin(). This occurs
because the cleaner ioctl falls into an infinite loop if
nilfs_segctor_construct() repeatedly returns -EROFS (e.g. the device
is remounted as read-only after an I/O error).
Currently in nilfs_clean_segments(), if err is non-zero, it logs the
error and sleeps but doesn't abort when it encounters a terminal error
like -EROFS. This causes the thread to loop forever.
Fix this by breaking out of the loop if nilfs_segctor_construct()
returns -EROFS. This matches the behaviour in
nilfs_segctor_write_out(), which also handles -EROFS. |
| In the Linux kernel, the following vulnerability has been resolved:
clk: mediatek: pllfh: Fix IO remapping leak in register_pllfhs error path
When mtk_clk_register_pllfhs function fails to register a PLL, it
unregisters all PLLs and cleans up itself in its error path before
returning, so the function callers don't need to do it.
But contrary to mtk_clk_unregister_pllfhs function, that does almost
the same sequence, it does not free the IO memory mapped on fhctl node,
leading to a leak.
Fix this leak by factorizing the cleanup sequence in a new private
function and use it both mtk_clk_register_pllfhs and
mtk_clk_unregister_pllfhs functions.
Also, change the loop index start value to avoid the -1 operation on
index at each loop. |
| In the Linux kernel, the following vulnerability has been resolved:
misc: ad525x_dpot: use driver core groups for sysfs files
ad_dpot_probe() creates per-RDAC sysfs files manually and then
optionally creates the command sysfs group. This leaves probe responsible
for rolling back partial sysfs state and makes remove responsible for
matching every file that probe created.
Move the device attributes into driver core dev_groups for the I2C and
SPI drivers and use an is_visible() callback to expose only the
attributes supported by the probed device. With this shape, the driver
core creates the sysfs files only after probe succeeds and removes them
before the remove callback frees the driver data. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/rockchip: dw_dp: Release core resources
Core resources such as the DisplayPort AUX channel get initialized and
registered during dw_dp_bind(), but are never unregistered, which may
lead to memory leaks and/or use-after-free:

Since a previous commit exported dw_dp_unbind() function in DW DP core
library to take care of the necessary cleanup, use this in the
component's unbind() callback, as well as in its bind() error path. |
| In the Linux kernel, the following vulnerability has been resolved:
platform/x86: dell-wmi-base: Fix resource leak on module load failure
We need to properly clean up the SMBIOS request and the privacy driver
when the module load fails. |
| In the Linux kernel, the following vulnerability has been resolved:
bus: mhi: ep: Fix device refcount leak in the error path of MHI device creation
mhi_ep_create_device() takes one device reference for the UL channel and
another for the DL channel after allocating the transfer device. These
references are normally released by mhi_ep_destroy_device() before the
device itself is removed.
If dev_set_name() or device_add() fails, the error path currently drops
only one reference. The remaining channel references keep the device
from being released and leave the channels associated with a device that
was never registered.
Route both failures through a common unwind path that drops the DL
channel reference, the UL channel reference, and the initial reference
from device_initialize(). |
| In the Linux kernel, the following vulnerability has been resolved:
staging: media: ipu7: fix pm_runtime refcount leak in ipu7_resume()
ipu7_resume() calls pm_runtime_get_sync() before resuming the device.
If the runtime PM resume fails, the usage count remains incremented, but
the error path returns without dropping the reference.
Use pm_runtime_resume_and_get() instead, which balances the usage count
on failure and avoids the leak. Keep returning 0 on error, as resume
callbacks should not propagate failures to the PM core, matching the
behaviour of the ipu6 driver. |
| In the Linux kernel, the following vulnerability has been resolved:
clk: qcom: gdsc: tear down per-domain genpds in gdsc_unregister()
gdsc_unregister() removes the OF provider entry and tears down the
parent/subdomain wiring, but never calls pm_genpd_remove() on the
individual generic_pm_domain structures registered by gdsc_init():
void gdsc_unregister(struct gdsc_desc *desc)
{
struct device *dev = desc->dev;
size_t num = desc->num;
gdsc_pm_subdomain_remove(desc, num);
of_genpd_del_provider(dev->of_node);
}
That leaves dangling entries on the global gpd_list. After a provider
unbind/rebind cycle (deferred-probe replay during early boot, real
module unload of a clk driver that owns GDSCs, or an OF-overlay tear-
down) the next gdsc_init() will end up trying to re-register a name
that is still in the list and pm_genpd_init() returns -EEXIST.
While we are here, flip the order so the consumer-facing OF provider
entry is the first thing removed -- otherwise a fresh
of_genpd_get_from_provider() call racing with the teardown could
attach to a domain that is mid-removal.
Iterate the scs[] array and pm_genpd_remove() each registered domain
after the subdomain links are torn down. The regulators stay devm-
managed (devm_regulator_get_optional() in gdsc_register()), so the
release happens automatically when the underlying device is unbound;
just the genpd accounting needs to be undone explicitly. |
| A vulnerability was found in O-RAN-SC SMO OAM 2025-06-10. Affected by this vulnerability is an unknown functionality of the component VES Collector. Performing a manipulation results in allocation of resources. The attack may be initiated remotely. The exploit has been made public and could be used. The project was informed of the problem early through a bug report but has not responded yet. |
| In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Free transport channel on IDR failure
If transport channel setup succeeds but the following IDR insertion fails,
the error path destroys the transport device and frees the channel info
without invoking the transport cleanup callback.
Call chan_free() before destroying the device so transport specific
resources such as IRQs, mailbox channels and mapped shared memory are
released consistently with the normal teardown path. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/hfi1: Free RX data on late probe failure
hfi1_init_dd() allocates the shared AIP/VNIC RX support before returning.
If hfi1_init() or hfi1_register_ib_device() later fails, init_one() tears
down the device data without calling hfi1_free_rx(). This leaks netdev_rx
and its dummy netdev.
Free the RX support after IB unregistration and before postinit_cleanup(),
as done on normal device removal. |
| In the Linux kernel, the following vulnerability has been resolved:
remoteproc: qcom_q6v5_adsp: Fix reference leak for device node
When calling of_parse_phandle_with_args(), the caller is responsible
to call of_node_put() to release the reference of device node.
In adsp_map_carveout, it does not release the reference. |
| In the Linux kernel, the following vulnerability has been resolved:
ext4: fix buffer_head leak in ext4_init_orphan_info
ext4_init_orphan_info() reads orphan file blocks with ext4_bread()
and stores the returned buffer_head in oi->of_binfo[i].ob_bh.
If ext4_bread() succeeds but the orphan block magic or checksum
validation fails, the function jumps to out_free. However, the old
out_free loop starts releasing buffers from i - 1, so the current
buffer_head at index i is skipped.
This leaks the buffer_head reference obtained by ext4_bread() on the
bad magic and bad checksum error paths.
Fix this by tracking the number of successfully read buffer_heads and
releasing exactly those buffer_heads on the error path. |
| In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Drop handle on protocol bind failures
The SCMI bus notifier acquires an SCMI handle when the driver core emits
BUS_NOTIFY_BIND_DRIVER, before invoking the protocol driver probe
callback. The protocol probe path only checks whether sdev->handle is
set.
If device_link_add() fails after the handle has been acquired, the
protocol device can still bind with a valid handle but without the
dependency link to the SCMI parent. A concurrent parent unbind can then
miss the child and tear down the SCMI instance while the child still
holds a handle into it.
If the protocol driver probe later fails, for example with
-EPROBE_DEFER, the driver core emits BUS_NOTIFY_DRIVER_NOT_BOUND rather
than BUS_NOTIFY_UNBOUND_DRIVER. The SCMI notifier only released the
handle on BUS_NOTIFY_UNBOUND_DRIVER, so each failed protocol-device bind
leaked the SCMI instance users refcount and left sdev->handle set after
the failed probe.
Make the link helper report failure and drop the acquired handle if the
link cannot be created. Also handle BUS_NOTIFY_DRIVER_NOT_BOUND in the
same cleanup path used for unbind so failed probes balance the earlier
BUS_NOTIFY_BIND_DRIVER acquisition. |
| In the Linux kernel, the following vulnerability has been resolved:
riscv, bpf: Fix memory leak in bpf_jit_free
When bpf_int_jit_compile() is called for subprograms, it returns early
during the first pass (!prog->is_func || extra_pass is false), keeping
ctx->offset alive for the subsequent extra pass.
If JIT compilation fails for a later subprogram, the BPF core aborts
and calls bpf_jit_free() to clean up the first subprogram. However,
bpf_jit_free() fails to free jit_data->ctx.offset, which causes a
memory leak of the JIT context offsets array.
Fix this by adding the missing kfree(jit_data->ctx.offset) in
bpf_jit_free(). |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/cxgb4: free STAG index when TPT entry write fails
write_tpt_entry() allocates a new STAG index with c4iw_get_resource() and
bumps stats.stag.cur before programming the entry. When
write_adapter_mem() fails, it returns the error without releasing the index
or reversing the statistic. No MR is inserted into rhp->mrs, so
deregistration never reclaims it, leaking the index until device teardown.
Record whether this call allocated the index and, on a failed write, return
it to tpt_table and decrement stats.stag.cur. Key the rollback on both the
write error and that flag, not the error alone: a non-reset update carries
a caller-owned STAG that this call did not allocate and must not free. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/msm/dsi: Drop dev_pm_opp_set_rate(0)
dev_pm_opp_set_rate(0) removes the vote specified in required-opps but
does not actually park the clock, making it run without the necessary
power backing. Drop the explicit call to it.
Every call site of ops->link_clk_disable() is followed by
pm_runtime_put(), so the power vote will be rescinded if deemed safe.
