DEBIAN-CVE-2026-98181
No affected components available
In the Linux kernel, the following vulnerability has been resolved: drm/gud: fix out-of-bounds write in gud_plane_atomic_check() The plane property loop uses req->properties[num_properties + i] as write index while simultaneously incrementing num_properties inside the loop. At iteration i, num_properties has also incremented by i, so the write is done at initial_num_properties + 2*i, skipping every other index and advancing by 2 per iteration. With just 2 connector and 32 plane properties the last write happens at index 64, one slot past the end of the 64-slot (indices 0–63) allocation. A USB device can trigger OOB by advertising the maximum number of properties. Fix by dropping the redundant + i; num_properties is already the correct running index, as gud_connector_fill_properties() fills the preceding slots.
