CVE-2024-38390 drm/msm/a6xx: Avoid a nullptr dereference when speedbin setting fails

In the Linux kernel, the following vulnerability has been resolved: drm/msm/a6xx: Avoid a nullptr dereference when speedbin setting fails Calling a6xxdestroy before adrenogpuinit leads to a null pointer dereference on: msmgpucleanup : platformsetdrvdatagpu-pdev, NULL; as gpu-pdev is only assigned...

CVE-2024-38390

CVE-2024-38390 affects the Linux kernel DRM/MSM a6xx path. The vulnerability arises when speedbin setting fails, causing a null pointer dereference during cleanup if msm_gpu_init() did not complete (gpu->pdev is only assigned in a6xx_gpu_init -> adreno_gpu_init -> msm_gpu_init). The cano...

Linux kernel security vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel, which originates in the drm/msm/a6xx module that dereferences a null pointer when the speedbin setting fails...

kernel: cpufreq: qcom: fix memory leak in error path

A memory leak vulnerability was found in the Qualcomm cpufreq driver in the Linux kernel. When the speedbin length is incorrect, the error handling path fails to free the allocated speedbin buffer, leading to a memory leak. Over time, this can cause resource exhaustion and system instability...
