| In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: E-Switch, Fix an Oops in error handling code
The error handling dereferences "vport". There is nothing we can do if
it is an error pointer except returning the error code. |
| A flaw was found in the Linux kernel’s IP framework for transforming packets (XFRM subsystem). This issue may allow a malicious user with CAP_NET_ADMIN privileges to directly dereference a NULL pointer in xfrm_update_ae_params(), leading to a possible kernel crash and denial of service. |
| An issue was discovered in the NPU driver in Samsung Mobile Processor Exynos 1280, 2200, 1380, 1480, 2400, 1580, 2500. There is a NULL Pointer Dereference of hdev in the __npu_vertex_bootup function. |
| An issue was discovered in NPU in Samsung Mobile Processor Exynos 1380 through July 2025. There is a NULL Pointer Dereference of profiler.node in the npu_vertex_profileoff function. |
| Serving WebSocket protocol upgrades over a HTTP/2 connection could result in a Null Pointer dereference, leading to a crash of the server process, degrading performance. |
| A flaw was found in the Linux kernel's NVMe driver. This issue may allow an unauthenticated malicious actor to send a set of crafted TCP packages when using NVMe over TCP, leading the NVMe driver to a NULL pointer dereference in the NVMe driver, causing kernel panic and a denial of service. |
| A flaw was found in the Linux kernel's NVMe driver. This issue may allow an unauthenticated malicious actor to send a set of crafted TCP packages when using NVMe over TCP, leading the NVMe driver to a NULL pointer dereference in the NVMe driver, causing kernel panic and a denial of service. |

| In the Linux kernel, the following vulnerability has been resolved:
ublk: fix handling recovery & reissue in ublk_abort_queue()
Commit 8284066946e6 ("ublk: grab request reference when the request is handled
by userspace") doesn't grab request reference in case of recovery reissue.
Then the request can be requeued & re-dispatch & failed when canceling
uring command.
If it is one zc request, the request can be freed before io_uring
returns the zc buffer back, then cause kernel panic:

| A null pointer dereference flaw was found in the Linux kernel API for the cryptographic algorithm scatterwalk functionality. This issue occurs when a user constructs a malicious packet with specific socket configuration, which could allow a local user to crash the system or escalate their privileges on the system. |
| A null pointer dereference flaw was found in the hugetlbfs_fill_super function in the Linux kernel hugetlbfs (HugeTLB pages) functionality. This issue may allow a local user to crash the system or potentially escalate their privileges on the system. |
| A NULL pointer dereference flaw was found in the Linux kernel ipv4 stack. The socket buffer (skb) was assumed to be associated with a device before calling __ip_options_compile, which is not always the case if the skb is re-routed by ipvs. This issue may allow a local user with CAP_NET_ADMIN privileges to crash the system. |
| A Null pointer dereference problem was found in ida_free in lib/idr.c in the Linux Kernel. This issue may allow an attacker using this library to cause a denial of service problem due to a missing check at a function return. |
| A null pointer dereference vulnerability was found in nft_dynset_init() in net/netfilter/nft_dynset.c in nf_tables in the Linux kernel. This issue may allow a local attacker with CAP_NET_ADMIN user privilege to trigger a denial of service. |
| In the Linux kernel, the following vulnerability has been resolved:
tracing: kprobe: Fix potential null-ptr-deref on trace_array in kprobe_event_gen_test_exit()
When test_gen_kprobe_cmd() failed after kprobe_event_gen_cmd_end(), it
will goto delete, which will call kprobe_event_delete() and release the
corresponding resource. However, the trace_array in gen_kretprobe_test
will point to the invalid resource. Set gen_kretprobe_test to NULL
after called kprobe_event_delete() to prevent null-ptr-deref.

| In the Linux kernel, the following vulnerability has been resolved:
drm/msm/dpu: Fix error pointers in dpu_plane_virtual_atomic_check
The function dpu_plane_virtual_atomic_check was dereferencing pointers
returned by drm_atomic_get_plane_state without checking for errors. This
could lead to undefined behavior if the function returns an error pointer.
This commit adds checks using IS_ERR to ensure that plane_state is
valid before dereferencing them.
Similar to commit da29abe71e16
("drm/amd/display: Fix error pointers in amdgpu_dm_crtc_mem_type_changed").
Patchwork: https://patchwork.freedesktop.org/patch/643132/ |
| In the Linux kernel, the following vulnerability has been resolved:
i2c: cros-ec-tunnel: defer probe if parent EC is not present
When i2c-cros-ec-tunnel and the EC driver are built-in, the EC parent
device will not be found, leading to NULL pointer dereference.
That can also be reproduced by unbinding the controller driver and then
loading i2c-cros-ec-tunnel module (or binding the device).

| In the Linux kernel, the following vulnerability has been resolved:
drm/mediatek: dp: drm_err => dev_err in HPD path to avoid NULL ptr
The function mtk_dp_wait_hpd_asserted() may be called before the
`mtk_dp->drm_dev` pointer is assigned in mtk_dp_bridge_attach().
Specifically it can be called via this callpath:
- mtk_edp_wait_hpd_asserted
- [panel probe]
- dp_aux_ep_probe
Using "drm" level prints anywhere in this callpath causes a NULL
pointer dereference. Change the error message directly in
mtk_dp_wait_hpd_asserted() to dev_err() to avoid this. Also change the
error messages in mtk_dp_parse_capabilities(), which is called by
mtk_dp_wait_hpd_asserted().
While touching these prints, also add the error code to them to make
future debugging easier. |
| In the Linux kernel, the following vulnerability has been resolved:
mfd: ene-kb3930: Fix a potential NULL pointer dereference
The off_gpios could be NULL. Add missing check in the kb3930_probe().
This is similar to the issue fixed in commit b1ba8bcb2d1f
("backlight: hx8357: Fix potential NULL pointer dereference").
This was detected by our static analysis tool. |
