CVSS v3.1 |
| A vulnerability was found in HDF5 up to 1.14.6 and classified as problematic. This issue affects the function H5O__cache_chk_serialize of the file src/H5Ocache.c. The manipulation leads to null pointer dereference. An attack has to be approached locally. The exploit has been disclosed to the public and may be used. |
| DaveGamble/cJSON cJSON 1.7.8 is affected by: Improper Check for Unusual or Exceptional Conditions. The impact is: Null dereference, so attack can cause denial of service. The component is: cJSON_GetObjectItemCaseSensitive() function. The attack vector is: crafted json file. The fixed version is: 1.7.9 and later. |
| cJSON v1.7.16 was discovered to contain a segmentation violation via the function cJSON_SetValuestring at cJSON.c. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Atom Integrated System Info v2_2 for DCN35
New request from KMD/VBIOS in order to support new UMA carveout
model. This fixes a null dereference from accessing
Ctx->dc_bios->integrated_info while it was NULL.
DAL parses through the BIOS and extracts the necessary
integrated_info but was missing a case for the new BIOS
version 2.3. |
| Upon investigtion upstream maintainers discovered this was not a real issue. See the references for more details. See: https://gitlab.gnome.org/GNOME/libsoup/-/issues/430#note_2494090. |
| Null pointer dereference vulnerability in the application exit cause module
Impact: Successful exploitation of this vulnerability may affect function stability. |
| After Effects versions 25.2, 24.6.6 and earlier are affected by a NULL Pointer Dereference vulnerability that could lead to application denial-of-service. An attacker could exploit this vulnerability to crash the application, causing disruption to services. Exploitation of this issue requires user interaction in that a victim must open a malicious file. |
| Illustrator versions 28.7.6, 29.5.1 and earlier are affected by a NULL Pointer Dereference vulnerability that could lead to application denial-of-service. An attacker could exploit this vulnerability to crash the application, causing a disruption in service. Exploitation of this issue requires user interaction in that a victim must open a malicious file. |
| Adobe Framemaker versions 2020.8, 2022.6 and earlier are affected by a NULL Pointer Dereference vulnerability that could lead to application denial-of-service. An attacker could exploit this vulnerability to crash the application, causing a disruption in service. Exploitation of this issue requires user interaction in that a victim must open a malicious file. |

| in OpenHarmony v5.0.2 and prior versions allow a local attacker cause DOS through NULL pointer dereference. |
| A vulnerability classified as critical was found in RT-Thread 5.1.0. This vulnerability affects the function csys_sendto of the file rt-thread/components/lwp/lwp_syscall.c. The manipulation of the argument to leads to null pointer dereference. |
| Substance3D - Viewer versions 0.22 and earlier are affected by a NULL Pointer Dereference vulnerability that could lead to application denial-of-service. An attacker could exploit this vulnerability to crash the application, causing disruption in service. Exploitation of this issue requires user interaction in that a victim must open a malicious file. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Add NULL check for clk_mgr and clk_mgr->funcs in dcn401_init_hw
This commit addresses a potential null pointer dereference issue in the
`dcn401_init_hw` function. The issue could occur when `dc->clk_mgr` or
`dc->clk_mgr->funcs` is null.
The fix adds a check to ensure `dc->clk_mgr` and `dc->clk_mgr->funcs` is
not null before accessing its functions. This prevents a potential null
pointer dereference.
Reported by smatch:
drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn401/dcn401_hwseq.c:416 dcn401_init_hw() error: we previously assumed 'dc->clk_mgr' could be null (see line 225) |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Add NULL check for function pointer in dcn401_set_output_transfer_func
This commit adds a null check for the set_output_gamma function pointer
in the dcn401_set_output_transfer_func function. Previously,
set_output_gamma was being checked for null, but then it was being
dereferenced without any null check. This could lead to a null pointer
dereference if set_output_gamma is null.
To fix this, we now ensure that set_output_gamma is not null before
dereferencing it. We do this by adding a null check for set_output_gamma
before the call to set_output_gamma. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Add null check for 'afb' in amdgpu_dm_update_cursor (v2)
This commit adds a null check for the 'afb' variable in the
amdgpu_dm_update_cursor function. Previously, 'afb' was assumed to be
null at line 8388, but was used later in the code without a null check.
This could potentially lead to a null pointer dereference.
Changes since v1:
- Moved the null check for 'afb' to the line where 'afb' is used. (Alex)
Fixes the below:
drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:8433 amdgpu_dm_update_cursor()
error: we previously assumed 'afb' could be null (see line 8388) |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Check stream_status before it is used
[WHAT & HOW]
dc_state_get_stream_status can return null, and therefore null must be
checked before stream_status is used.
This fixes 1 NULL_RETURNS issue reported by Coverity. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Run DC_LOG_DC after checking link->link_enc
[WHAT]
The DC_LOG_DC should be run after link->link_enc is checked, not before.
This fixes 1 REVERSE_INULL issue reported by Coverity. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Add otg_master NULL check within resource_log_pipe_topology_update
[Why]
Coverity reports NULL_RETURN warning.
[How]
Add otg_master NULL check. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Fix NULL pointer dereference for DTN log in DCN401

This error happens when the color log tries to read the gamut remap
information from DCN401 which is not initialized in the dcn401_dpp_funcs
which leads to a null pointer dereference. This commit addresses this
issue by adding a proper guard to access the gamut_remap callback in
case the specific ASIC did not implement this function. |
