      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/edid: fix OOB read in drm_parse_tiled_block()\n\ndrm_parse_tiled_block() casts the DisplayID block to a\nstruct displayid_tiled_block and reads the full fixed layout up to\ntile->topology_id[7] without checking block->num_bytes. The DisplayID\niterator only validates the declared payload length, so a crafted EDID\ncan advertise a tiled-display block (tag DATA_BLOCK_TILED_DISPLAY, or\nDATA_BLOCK_2_TILED_DISPLAY_TOPOLOGY for v2.0) with a small num_bytes at\nthe end of a DisplayID extension. The read then runs past the end of the\nexact-sized kmemdup()'d EDID allocation, a heap out-of-bounds read.\n\nReject blocks shorter than the spec's 22-byte tiled payload before\nreading the fixed struct, as drm_parse_vesa_mso_data() already does.\n\n  BUG: KASAN: slab-out-of-bounds in drm_edid_connector_update\n  Read of size 2 at addr ffff888010077700 by task exploit/147\n   dump_stack_lvl (lib/dump_stack.c:94 ...)\n   print_report (mm/kasan/report.c:378 ...)\n   kasan_report (mm/kasan/report.c:595)\n   drm_edid_connector_update (drivers/gpu/drm/drm_edid.c:7581)\n   bochs_connector_helper_get_modes (drivers/gpu/drm/tiny/bochs.c:574)\n   drm_helper_probe_single_connector_modes (drivers/gpu/drm/drm_probe_helper.c:426)\n   status_store (drivers/gpu/drm/drm_sysfs.c:219)\n   ...\n   vfs_write (fs/read_write.c:595 fs/read_write.c:688)\n   ksys_write (fs/read_write.c:740)",
