CVE-2026-74470 scsi: scsi_debug: Fix REPORT ZONES alloc_len underflow OOB write

In the Linux kernel, the following vulnerability has been resolved: scsi: scsidebug: Fix REPORT ZONES alloclen underflow OOB write respreportzones sizes the reply buffer from the CDB allocation length. The v3 fix rounds alloclen up with ALIGN before deriving the descriptor count: repmaxzones =...

CVE-2026-74470

The CVE-2026-74470 issue affects the Linux kernel in the scsi_debug path for REPORT ZONES replies. The vulnerability arises from an alloc_len handling bug where resp_report_zones() derives arr_len and rep_max_zones from the CDB alloc_len; for large alloc_len (0xFFFFFFC1..0xFFFFFFFF) ALIGN() can p...

In the Linux kernel, the following vulnerability has been resolved: drm/panthor: reject firmware sections with oversized data In panthorfwloadsectionentry, the data size to copy is calculated without validating it against the allocated sectionsize: section-data.size = hdr.data.end - hdr.data.star...

CVE-2026-74444 drm/vmwgfx: validate DRAW_PRIMITIVES header size before division

In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: validate DRAWPRIMITIVES header size before division vmwcmddraw computes maxnum = header-size - sizeofcmd-body / sizeofdecl; where header-size is u32 and is taken straight from the user-supplied command stream. When...

CVE-2026-74444

The vulnerability CVE-2026-74444 affects the Linux kernel DRM vmwgfx driver. In vmw_cmd_draw, the header size from user input can cause an unsigned subtraction (header->size - sizeof(cmd->body)) to wrap to ~4 GiB when header->size is undersized, leading to a large maxnum and an out-of-bo...
