CVE-2026-68277 drm/dp/mst: fix OOB reads on 2-byte fields in sideband reply parsers

In the Linux kernel, the following vulnerability has been resolved: drm/dp/mst: fix OOB reads on 2-byte fields in sideband reply parsers Three sideband reply parsers read 16-bit fields as: val = raw-msgidx msgidx+1; and check bounds only after the fact.

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...
