| In the Linux kernel, the following vulnerability has been resolved:
accel/rocket: fix unwinding in error path in rocket_probe
When rocket_core_init() fails (as could be the case with EPROBE_DEFER),
we need to properly unwind by decrementing the counter we just
incremented and if this is the first core we failed to probe, remove the
rocket DRM device with rocket_device_fini() as well. This matches the
logic in rocket_remove(). Failing to properly unwind results in
out-of-bounds accesses. |
| In the Linux kernel, the following vulnerability has been resolved:
i3c: dw: Fix memory leak in dw_i3c_master_i2c_xfers()
The dw_i3c_master_i2c_xfers() function allocates memory for the xfer
structure using dw_i3c_master_alloc_xfer(). If pm_runtime_resume_and_get()
fails, the function returns without freeing the allocated xfer, resulting
in a memory leak.
Add a dw_i3c_master_free_xfer() call to the error path to ensure the
allocated memory is properly freed.
Compile tested only. Issue found using a prototype static analysis tool
and code review. |
| In the Linux kernel, the following vulnerability has been resolved:
spi: ch341: fix memory leaks on probe failures
Make sure to deregister the controller, disable pins, and kill and free
the RX URB on probe failures to mirror disconnect and avoid memory
leaks and use-after-free.
Also add an explicit URB kill on disconnect for symmetry (even if that
is not strictly required as USB core would have stopped it in the
current setup). |
| In the Linux kernel, the following vulnerability has been resolved:
mm/damon/stat: fix memory leak on damon_start() failure in damon_stat_start()
Destroy the DAMON context and reset the global pointer when damon_start()
fails. Otherwise, the context allocated by damon_stat_build_ctx() is
leaked, and the stale damon_stat_context pointer will be overwritten on
the next enable attempt, making the old allocation permanently
unreachable. |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: caam - fix netdev memory leak in dpaa2_caam_probe
When commit 0e1a4d427f58 ("crypto: caam: Unembed net_dev structure in
dpaa2") converted embedded net_device to dynamically allocated pointers,
it added cleanup in dpaa2_dpseci_disable() but missed adding cleanup in
dpaa2_dpseci_free() for error paths.
This causes memory leaks when dpaa2_dpseci_dpio_setup() fails during probe
due to DPIO devices not being ready yet. The kernel's deferred probe
mechanism handles the retry successfully, but the netdevs allocated during
the failed probe attempt are never freed, resulting in kmemleak reports
showing multiple leaked netdev-related allocations all traced back to
dpaa2_caam_probe().
Fix this by preserving the CPU mask of allocated netdevs during setup and
using it for cleanup in dpaa2_dpseci_free(). This approach ensures that
only the CPUs that actually had netdevs allocated will be cleaned up,
avoiding potential issues with CPU hotplug scenarios. |
| In the Linux kernel, the following vulnerability has been resolved:
accel/amdxdna: Fix memory leak in amdxdna_ubuf_map
The amdxdna_ubuf_map() function allocates memory for sg and
internal sg table structures, but it fails to free them if subsequent
operations (sg_alloc_table_from_pages or dma_map_sgtable) fail. |
| In the Linux kernel, the following vulnerability has been resolved:
tpm2-sessions: Fix missing tpm_buf_destroy() in tpm2_read_public()
tpm2_read_public() calls tpm_buf_init() but fails to call
tpm_buf_destroy() on two exit paths, leaking a page allocation:
1. When name_size() returns an error (unrecognized hash algorithm),
the function returns directly without destroying the buffer.
2. On the success path, the buffer is never destroyed before
returning.
All other error paths in the function correctly call
tpm_buf_destroy() before returning.
Fix both by adding the missing tpm_buf_destroy() calls. |
| In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix chunk map leak in btrfs_map_block() after btrfs_chunk_map_num_copies()
Fix a chunk map leak in btrfs_map_block(): if we return early with -EINVAL,
we're not freeing the chunk map that we've just looked up. |
| In the Linux kernel, the following vulnerability has been resolved:
net: ti: icssg-prueth: Fix memory leak in XDP_DROP for non-zero-copy mode
Page recycling was removed from the XDP_DROP path in emac_run_xdp() to
avoid conflicts with AF_XDP zero-copy mode, which uses xsk_buff_free()
instead.
However, this causes a memory leak when running XDP programs that drop
packets in non-zero-copy mode (standard page pool mode). The pages are
never returned to the page pool, leading to OOM conditions.
Fix this by handling cleanup in the caller, emac_rx_packet().
When emac_run_xdp() returns ICSSG_XDP_CONSUMED for XDP_DROP, the
caller now recycles the page back to the page pool. The zero-copy
path, emac_rx_packet_zc() already handles cleanup correctly with
xsk_buff_free(). |
| In the Linux kernel, the following vulnerability has been resolved:
mctp: i2c: fix skb memory leak in receive path
When 'midev->allow_rx' is false, the newly allocated skb isn't consumed
by netif_rx(), it needs to free the skb directly. |
| A specially crafted domain can be used to cause a memory leak in a BIND resolver simply by querying this domain.
This issue affects BIND 9 versions 9.20.0 through 9.20.20, 9.21.0 through 9.21.19, and 9.20.9-S1 through 9.20.20-S1.
BIND 9 versions 9.18.0 through 9.18.46 and 9.18.11-S1 through 9.18.46-S1 are NOT affected. |
| In the Linux kernel, the following vulnerability has been resolved:
soc: microchip: mpfs: Fix memory leak in mpfs_sys_controller_probe()
In mpfs_sys_controller_probe(), if of_get_mtd_device_by_node() fails,
the function returns immediately without freeing the allocated memory
for sys_controller, leading to a memory leak.
Fix this by jumping to the out_free label to ensure the memory is
properly freed.
Also, consolidate the error handling for the mbox_request_channel()
failure case to use the same label. |
| Netty is an asynchronous, event-driven network application framework. From 4.2.0.Final to 4.2.13.Final , Netty's epoll transport fails to detect and close TCP connections that receive a RST after being half-closed, leading to stale channels that are never cleaned up and, in some code paths, a 100% CPU busy-loop in the event loop thread. This vulnerability is fixed in 4.2.13.Final. |
| In the Linux kernel, the following vulnerability has been resolved:
net: dsa: microchip: Fix error path in PTP IRQ setup
If request_threaded_irq() fails during the PTP message IRQ setup, the
newly created IRQ mapping is never disposed. Indeed, the
ksz_ptp_irq_setup()'s error path only frees the mappings that were
successfully set up.
Dispose the newly created mapping if the associated
request_threaded_irq() fails at setup. |
| In the Linux kernel, the following vulnerability has been resolved:
btrfs: add missing RCU unlock in error path in try_release_subpage_extent_buffer()
Call rcu_read_lock() before exiting the loop in
try_release_subpage_extent_buffer() because there is a rcu_read_unlock()
call past the loop.
This has been detected by the Clang thread-safety analyzer. |
| In the Linux kernel, the following vulnerability has been resolved:
net: ncsi: fix skb leak in error paths
Early return paths in NCSI RX and AEN handlers fail to release
the received skb, resulting in a memory leak.
Specifically, ncsi_aen_handler() returns on invalid AEN packets
without consuming the skb. Similarly, ncsi_rcv_rsp() exits early
when failing to resolve the NCSI device, response handler, or
request, leaving the skb unfreed. |
| In the Linux kernel, the following vulnerability has been resolved:
media: uvcvideo: Return queued buffers on start_streaming() failure
Return buffers if streaming fails to start due to uvc_pm_get() error.
This bug may be responsible for a warning I got running
while :; do yavta -c3 /dev/video0; done
on an xHCI controller which failed under this workload.
I had no luck reproducing this warning again to confirm.
xhci_hcd 0000:09:00.0: HC died; cleaning up
usb 13-2: USB disconnect, device number 2
WARNING: CPU: 2 PID: 29386 at drivers/media/common/videobuf2/videobuf2-core.c:1803 vb2_start_streaming+0xac/0x120 |
| In the Linux kernel, the following vulnerability has been resolved:
misc: ti_fpc202: fix a potential memory leak in probe function
Use for_each_child_of_node_scoped() to simplify the code and ensure the
device node reference is automatically released when the loop scope
ends. |
| In the Linux kernel, the following vulnerability has been resolved:
media: tegra-video: Fix memory leak in __tegra_channel_try_format()
The state object allocated by __v4l2_subdev_state_alloc() must be freed
with __v4l2_subdev_state_free() when it is no longer needed.
In __tegra_channel_try_format(), two error paths return directly after
v4l2_subdev_call() fails, without freeing the allocated 'sd_state'
object. This violates the requirement and causes a memory leak.
Fix this by introducing a cleanup label and using goto statements in the
error paths to ensure that __v4l2_subdev_state_free() is always called
before the function returns. |
| In the Linux kernel, the following vulnerability has been resolved:
mux: mmio: fix regmap leak on probe failure
The mmio regmap that may be allocated during probe is never freed.
Switch to using the device managed allocator so that the regmap is
released on probe failures (e.g. probe deferral) and on driver unbind. |
