Vulnerabilities > NULL Pointer Dereference
| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2025-02-26 | CVE-2022-49494 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mtd: rawnand: cadence: fix possible null-ptr-deref in cadence_nand_dt_probe() It will cause null-ptr-deref when using 'res', if platform_get_resource() returns NULL, so move using 'res' after devm_ioremap_resource() that will check it to avoid null-ptr-deref. And use devm_platform_get_and_ioremap_resource() to simplify code. | 5.5 |
| 2025-02-26 | CVE-2022-49495 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/msm/hdmi: check return value after calling platform_get_resource_byname() It will cause null-ptr-deref if platform_get_resource_byname() returns NULL, we need check the return value. Patchwork: https://patchwork.freedesktop.org/patch/482992/ | 5.5 |
| 2025-02-26 | CVE-2022-49498 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: Check for null pointer of pointer substream before dereferencing it Pointer substream is being dereferenced on the assignment of pointer card before substream is being null checked with the macro PCM_RUNTIME_CHECK. Although PCM_RUNTIME_CHECK calls BUG_ON, it still is useful to perform the the pointer check before card is assigned. | 5.5 |
| 2025-02-26 | CVE-2022-49499 | NULL Pointer Dereference vulnerability in Linux Kernel 5.18.1/5.18.2 In the Linux kernel, the following vulnerability has been resolved: drm/msm: Fix null pointer dereferences without iommu Check if 'aspace' is set before using it as it will stay null without IOMMU, such as on msm8974. | 5.5 |
| 2025-02-26 | CVE-2022-49510 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/omap: fix NULL but dereferenced coccicheck error Fix the following coccicheck warning: ./drivers/gpu/drm/omapdrm/omap_overlay.c:89:22-25: ERROR: r_ovl is NULL but dereferenced. Here should be ovl->idx rather than r_ovl->idx. | 5.5 |
| 2025-02-26 | CVE-2022-49516 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ice: always check VF VSI pointer values The ice_get_vf_vsi function can return NULL in some cases, such as if handling messages during a reset where the VSI is being removed and recreated. Several places throughout the driver do not bother to check whether this VSI pointer is valid. | 5.5 |
| 2025-02-26 | CVE-2022-49523 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ath11k: disable spectral scan during spectral deinit When ath11k modules are removed using rmmod with spectral scan enabled, crash is observed. | 5.5 |
| 2025-02-26 | CVE-2022-49527 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: media: venus: hfi: avoid null dereference in deinit If venus_probe fails at pm_runtime_put_sync the error handling first calls hfi_destroy and afterwards hfi_core_deinit. | 5.5 |
| 2025-02-26 | CVE-2022-49529 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/pm: fix the null pointer while the smu is disabled It needs to check if the pp_funcs is initialized while release the context, otherwise it will trigger null pointer panic while the software smu is not enabled.
