CVSSv4: 0 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a local user to cause a stack-based buffer overflow.
The vulnerability exists due to improper bounds checking in rockchip_dp_drm_encoder_enable() when formatting a device tree path into a 32-byte stack buffer. A local user can supply a device tree path that exceeds the buffer size to cause a stack-based buffer overflow.
