CVSS v3.1 |
| An authorized user could trigger a server crash by running a query with a 2dsphere index on a field that stores a GeoJSON GeometryCollection containing a Polygon with a strict-winding CRS.
Strict-winding polygons are intentionally unsupported for indexing, but the guard that rejects them does not inspect members of a GeometryCollection, allowing the unsafe path to be reached which ends with an ensuing null-pointer dereference. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/msm/gem: fix error handling in msm_ioctl_gem_info_get_metadata()
msm_ioctl_gem_info_get_metadata() always returns 0 regardless of
errors. When copy_to_user() fails or the user buffer is too small,
the error code stored in ret is ignored because the function
unconditionally returns 0. This causes userspace to believe the
ioctl succeeded when it did not.
Additionally, kmemdup() can return NULL on allocation failure, but
the return value is not checked. This leads to a NULL pointer
dereference in the subsequent copy_to_user() call.
Add the missing NULL check for kmemdup() and return ret instead of 0.
Note that the SET counterpart (msm_ioctl_gem_info_set_metadata)
correctly returns ret.

| In the Linux kernel, the following vulnerability has been resolved:
drm/xe/hdcp: Add NULL check for media_gt in intel_hdcp_gsc_check_status()
When media GT is disabled via configfs, there is no allocation for
media_gt, which is kept as NULL. In such scenario,
intel_hdcp_gsc_check_status() results in a kernel pagefault error due to
>->uc.gsc being evaluated as an invalid memory address.
Fix that by introducing a NULL check on media_gt and bailing out early
if so.
While at it, also drop the NULL check for gsc, since it can't be NULL if
media_gt is not NULL.
v2:
- Get address for gsc only after checking that gt is not NULL.
(Shuicheng)
- Drop the NULL check for gsc. (Shuicheng)
v3:
- Add "Fixes" and "Cc: <stable...>" tags. (Matt)

clk: qcom: gfx3d: add parent to parent request map
After commit d228ece36345 ("clk: divider: remove round_rate() in favor
of determine_rate()") determining GFX3D clock rate crashes, because the
passed parent map doesn't provide the expected best_parent_hw clock
(with the roundd_rate path before the offending commit the
best_parent_hw was ignored).
Set the field in parent_req in addition to setting it in the req,
fixing the crash.

drm/amd/display: Fix dc_link NULL handling in HPD init
amdgpu_dm_hpd_init() may see connectors without a valid dc_link.
The code already checks dc_link for the polling decision, but later
unconditionally dereferences it when setting up HPD interrupts.
Assign dc_link early and skip connectors where it is NULL.
Fixes the below:
drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm_irq.c:940 amdgpu_dm_hpd_init()

| In the Linux kernel, the following vulnerability has been resolved:
PCI: endpoint: Add missing NULL check for alloc_workqueue()
alloc_workqueue() can return NULL on memory allocation failure. Without
proper error checking, this may lead to a NULL pointer dereference when
queue_work() is later called with the NULL workqueue pointer in
epf_ntb_epc_init().
Add a NULL check immediately after alloc_workqueue() and return -ENOMEM on
failure to prevent the driver from loading with an invalid workqueue
pointer. |
| In the Linux kernel, the following vulnerability has been resolved:
gpio: cdev: Avoid NULL dereference in linehandle_create()
In linehandle_create(), there is a statement like this:
retain_and_null_ptr(lh);
Soon after, there is a debug printout that dereferences "lh", which
will crash things.
Avoid the crash by using handlereq.lines, which is the same value. |
| In the Linux kernel, the following vulnerability has been resolved:
spi: wpcm-fiu: Fix potential NULL pointer dereference in wpcm_fiu_probe()
platform_get_resource_byname() can return NULL, which would cause a crash
when passed the pointer to resource_size().
Move the fiu->memory_size assignment after the error check for
devm_ioremap_resource() to prevent the potential NULL pointer dereference. |
| In the Linux kernel, the following vulnerability has been resolved:
pinctrl: canaan: k230: Fix NULL pointer dereference when parsing devicetree
When probing the k230 pinctrl driver, the kernel triggers a NULL pointer
dereference. The crash trace showed:
[ 0.732084] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000068
[ 0.740737] ...
[ 0.776296] epc : k230_pinctrl_probe+0x1be/0x4fc
In k230_pinctrl_parse_functions(), we attempt to retrieve the device
pointer via info->pctl_dev->dev, but info->pctl_dev is only initialized
after k230_pinctrl_parse_dt() completes.
At the time of DT parsing, info->pctl_dev is still NULL, leading to
the invalid dereference of info->pctl_dev->dev.
Use the already available device pointer from platform_device
instead of accessing through uninitialized pctl_dev. |

| Ubuntu Linux 6.8, 6.17 and 7.0 contain SAUCE patches with a possible NULL pointer dereference in the handling of AppArmor notifications. The bug can be triggered by an unprivileged local user. This can lead to a kernel oops. |
| A flaw was found in Samba’s WINS server component when running as an Active Directory Domain Controller. The WINS protocol handlers for certain request types did not properly validate incoming packets, allowing an unauthenticated remote attacker to trigger a NULL pointer dereference and crash the WINS service using specially crafted UDP packets. |
| A NULL pointer dereference vulnerability has been reported to affect several QNAP operating system versions. If a remote attacker gains an administrator account, they can then exploit the vulnerability to launch a denial-of-service (DoS) attack.
We have already fixed the vulnerability in the following versions:

QuTS hero h5.2.9.3410 build 20260214 and later

| In the Linux kernel, the following vulnerability has been resolved:
iio: frequency: admv1013: fix NULL pointer dereference on str
When device_property_read_string() fails, str is left uninitialized
but the code falls through to strcmp(str, ...), dereferencing a garbage
pointer. Replace manual read/strcmp with
device_property_match_property_string() and consolidate the SE mode
enums into a single sequential enum, mapping to hardware register
values via a switch consistent with other bitfields in the driver.
Several cleanup patches have been applied to this driver recently so
this will need a manual backport. |
| In the Linux kernel, the following vulnerability has been resolved:
media: renesas: vsp1: Fix NULL pointer deref on module unload
When unloading the module on gen 4, we hit a NULL pointer dereference.
This is caused by the cleanup code calling vsp1_drm_cleanup() where it
should be calling vsp1_vspx_cleanup().
Fix this by checking the IP version and calling the drm or vspx function
accordingly, the same way as the init code does. |
