CVE-2026-68278

The CVE-2026-68278 entry documents a Linux kernel vulnerability in drm/dp/mst sideband processing (drm_dp_sideband_append_payload). Three bugs allow out-of-bounds writes when processing device-provided sideband replies: (1) zero-length curchunk_len underflow leading to 255-byte reads/writes beyon...

CVE-2026-68277

The CVE-2026-68277 entry concerns Linux kernel DRM/DP/MST sideband reply parsers where three 16-bit reads check bounds after reading, risking out-of-bounds access (idx == curlen). A fix was applied: pre-check using a single combined condition (idx + 2 > curlen) before each 2-byte read. Affecte...
