20
FAUCET Score

CVE-2025-38673 is a Linux kernel vulnerability affecting the drm/gem-framebuffer component, specifically a NULL-pointer dereference. This flaw arises because the dma_buf field in struct drm_gem_object can become NULL when user space releases the final GEM handle, leading to system instability. It carries a CVSSv3.1 score of 5.5 (Medium), indicating a local attack vector with low complexity, requiring low privileges, and resulting in high availability impact (system crash) without affecting confidentiality or integrity. There is currently no evidence of active exploitation, public exploit code, or significant community discussion surrounding this vulnerability.
