RDMA/mlx4: Fix resource leak on error in mlx4_ib_create_srq()
Sashiko points out that mlx4_srq_alloc() was not undone during error
unwind, add the missing call to mlx4_srq_free(). |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: Fix pin leak and publication ordering in __pkvm_init_vcpu()
Two bugs exist in the vCPU initialisation path:
1. If a check fails after hyp_pin_shared_mem() succeeds, the cleanup
path jumps to 'unlock' without calling unpin_host_vcpu() or
unpin_host_sve_state(), permanently leaking pin references on the
host vCPU and SVE state pages.
Extract a register_hyp_vcpu() helper that performs the checks and
the store. When register_hyp_vcpu() returns an error, call
unpin_host_vcpu() and unpin_host_sve_state() inline before falling
through to the existing 'unlock' label.
2. register_hyp_vcpu() publishes the new vCPU pointer into
'hyp_vm->vcpus[]' with a bare store, allowing a concurrent caller
of pkvm_load_hyp_vcpu() to observe a partially initialised vCPU
object.
Ensure the store uses smp_store_release() and the load uses
smp_load_acquire(). While 'vm_table_lock' currently serialises the
store and the load, these barriers ensure the reader sees the fully
initialised 'hyp_vcpu' object even if there were a lockless path or
if the lock's own ordering guarantees were insufficient for nested
object initialization. |
| In the Linux kernel, the following vulnerability has been resolved:
spi: ch341: fix devres lifetime
USB drivers bind to USB interfaces and any device managed resources
should have their lifetime tied to the interface rather than parent USB
device. This avoids issues like memory leaks when drivers are unbound
without their devices being physically disconnected (e.g. on probe
deferral or configuration changes).
Fix the controller and driver data lifetime so that they are released
on driver unbind.
Note that this also makes sure that the SPI controller is placed
correctly under the USB interface in the device tree. |
| In the Linux kernel, the following vulnerability has been resolved:
vsock/virtio: fix empty payload in tap skb for non-linear buffers
For non-linear skbs, virtio_transport_build_skb() goes through
virtio_transport_copy_nonlinear_skb() to copy the original payload
in the new skb to be delivered to the vsockmon tap device.
This manually initializes an iov_iter but does not set iov_iter.count.
Since the iov_iter is zero-initialized, the copy length is zero and no
payload is actually copied to the monitor interface, leaving data
un-initialized.
Fix this by removing the linear vs non-linear split and using
skb_copy_datagram_iter() with iov_iter_kvec() for all cases, as
vhost-vsock already does. This handles both linear and non-linear skbs,
properly initializes the iov_iter, and removes the now unused
virtio_transport_copy_nonlinear_skb().
While touching this code, let's also check the return value of
skb_copy_datagram_iter(), even though it's unlikely to fail. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/xe: Fix bo leak in xe_dma_buf_init_obj() on allocation failure
When drm_gpuvm_resv_object_alloc() fails, the pre-allocated storage bo
is not freed. Add xe_bo_free(storage) before returning the error.
xe_dma_buf_init_obj() calls xe_bo_init_locked(), which frees the bo on
error. Therefore, xe_dma_buf_init_obj() must also free the bo on its own
error paths. Otherwise, since xe_gem_prime_import() cannot distinguish
whether the failure originated from xe_dma_buf_init_obj() or from
xe_bo_init_locked(), it cannot safely decide whether the bo should be
freed.
Add comments documenting the ownership semantics: on success, ownership
of storage is transferred to the returned drm_gem_object; on failure,
storage is freed before returning.
v2: Add comments to explain the free logic.

| In the Linux kernel, the following vulnerability has been resolved:
EDAC/versalnet: Fix device name memory leak
The device name allocated via kzalloc() in init_one_mc() is assigned to
dev->init_name but never freed on the normal removal path. device_register()
copies init_name and then sets dev->init_name to NULL, so the name pointer
becomes unreachable from the device. Thus leaking memory.
Use a stack-local char array instead of using kzalloc() for name. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/xe: Fix dma-buf attachment leak in xe_gem_prime_import()
When xe_dma_buf_init_obj() fails, the attachment from
dma_buf_dynamic_attach() is not detached. Add dma_buf_detach() before
returning the error. Note: we cannot use goto out_err here because
xe_dma_buf_init_obj() already frees bo on failure, and out_err would
double-free it.

| In the Linux kernel, the following vulnerability has been resolved:
usb: usblp: fix heap leak in IEEE 1284 device ID via short response
usblp_ctrl_msg() collapses the usb_control_msg() return value to
0/-errno, discarding the actual number of bytes transferred. A broken
printer can complete the GET_DEVICE_ID control transfer short and the
driver has no way to know.
usblp_cache_device_id_string() reads the 2-byte big-endian length prefix
from the response and trusts it (clamped only to the buffer bounds).
The buffer is kmalloc(1024) at probe time. A device that sends exactly
two bytes (e.g. 0x03 0xFF, claiming a 1023-byte ID) leaves
device_id_string[2..1022] holding stale kmalloc heap.
That stale data is then exposed:
- via the ieee1284_id sysfs attribute (sprintf("%s", buf+2), truncated
at the first NUL in the stale heap), and
- via the IOCNR_GET_DEVICE_ID ioctl, which copy_to_user()s the full
claimed length regardless of NULs, up to 1021 bytes of uninitialized
heap, with the leak size chosen by the device.
Fix this up by just zapping the buffer with zeros before each request
sent to the device. |
| Ubuntu Linux 6.8, 6.17 and 7.0 contain SAUCE patches with a memory leak in the handling of big responses to AppArmor notifications. The bug can be triggered by an unprivileged local user. The memory leak could lead to resource exhaustion. |
| In Trusted Firmware-M through 1.3.0, cleaning up the memory allocated for a multi-part cryptographic operation (in the event of a failure) can prevent the abort() operation in the associated cryptographic library from freeing internal resources, causing a memory leak. |
| OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. Prior to version 0.9.0, the custom CappedConcurrentHashMap introduced for Java TLS state tracking never removes keys from its insertion-order queue when entries are deleted. In long-running instrumented JVMs, repeated connection churn can therefore grow the queue without bound and exhaust heap memory. This issue has been patched in version 0.9.0. |

| UltraJSON is a fast JSON encoder and decoder written in pure C with bindings for Python 3.7+. Prior to 5.12.1, when ujson.dump() writes to a file-like object and the write operation raises an exception, the serialized JSON string object is not decremented, leaking memory. Each failed write operation leaks the full size of the serialized payload. This vulnerability is fixed in 5.12.1. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: server: fix leak of active_num_conn in ksmbd_tcp_new_connection()
On kthread_run() failure in ksmbd_tcp_new_connection(), the transport is
freed via free_transport(), which does not decrement active_num_conn,
leaking this counter.
Replace free_transport() with ksmbd_tcp_disconnect(). |
| In the Linux kernel, the following vulnerability has been resolved:
pnfs/flexfiles: Fix memory leak in nfs4_ff_alloc_deviceid_node()
In nfs4_ff_alloc_deviceid_node(), if the allocation for ds_versions fails,
the function jumps to the out_scratch label without freeing the already
allocated dsaddrs list, leading to a memory leak.
Fix this by jumping to the out_err_drain_dsaddrs label, which properly
frees the dsaddrs list before cleaning up other resources. |
| In the Linux kernel, the following vulnerability has been resolved:
can: etas_es58x: allow partial RX URB allocation to succeed
When es58x_alloc_rx_urbs() fails to allocate the requested number of
URBs but succeeds in allocating some, it returns an error code.
This causes es58x_open() to return early, skipping the cleanup label
'free_urbs', which leads to the anchored URBs being leaked.
As pointed out by maintainer Vincent Mailhol, the driver is designed
to handle partial URB allocation gracefully. Therefore, partial
allocation should not be treated as a fatal error.
Modify es58x_alloc_rx_urbs() to return 0 if at least one URB has been
allocated, restoring the intended behavior and preventing the leak
in es58x_open(). |
| In the Linux kernel, the following vulnerability has been resolved:
can: gs_usb: gs_usb_receive_bulk_callback(): fix URB memory leak
In gs_can_open(), the URBs for USB-in transfers are allocated, added to the
parent->rx_submitted anchor and submitted. In the complete callback
gs_usb_receive_bulk_callback(), the URB is processed and resubmitted. In
gs_can_close() the URBs are freed by calling
usb_kill_anchored_urbs(parent->rx_submitted).
However, this does not take into account that the USB framework unanchors
the URB before the complete function is called. This means that once an
in-URB has been completed, it is no longer anchored and is ultimately not
released in gs_can_close().
Fix the memory leak by anchoring the URB in the
gs_usb_receive_bulk_callback() to the parent->rx_submitted anchor. |
| In the Linux kernel, the following vulnerability has been resolved:
dmaengine: qcom: gpi: Fix memory leak in gpi_peripheral_config()
Fix a memory leak in gpi_peripheral_config() where the original memory
pointed to by gchan->config could be lost if krealloc() fails.
The issue occurs when:
1. gchan->config points to previously allocated memory
2. krealloc() fails and returns NULL
3. The function directly assigns NULL to gchan->config, losing the
reference to the original memory
4. The original memory becomes unreachable and cannot be freed
Fix this by using a temporary variable to hold the krealloc() result
and only updating gchan->config when the allocation succeeds.
Found via static analysis and code review. |

dmaengine: dw: dmamux: fix OF node leak on route allocation failure
Make sure to drop the reference taken to the DMA master OF node also on
late route allocation failures. |
| In the Linux kernel, the following vulnerability has been resolved:
dmaengine: lpc18xx-dmamux: fix device leak on route allocation
Make sure to drop the reference taken when looking up the DMA mux
platform device during route allocation.
Note that holding a reference to a device does not prevent its driver
data from going away so there is no point in keeping the reference. |
