  "details": "In the Linux kernel, the following vulnerability has been resolved:  drm/panthor: harden firmware build-info bounds checks  panthor_fw_read_build_info() checks whether the metadata range fits in the firmware image with hdr.meta_start + hdr.meta_size. Both fields are u32, so the addition can wrap and let an out-of-bounds range pass validation.  The function also reads the \"git_sha: \" prefix without first checking that the metadata is long enough, and meta_size == 0 can underflow the NULL terminator index.  Use subtraction-based bounds checking and reject metadata that is too short to contain the expected prefix and trailing NULL byte.",
