-Subject: [PATCH] hw/display/qxl: validate primary surface stride against width
-
-The existing validation in qxl_create_guest_primary() checks that
-abs(stride) * height fits in vgamem_size and that stride is 4-byte
-aligned, but never checks that abs(stride) is large enough to hold one
-row of pixels for the declared width and format.
-
-A malicious guest can create a primary surface with a stride much
-smaller than width * bytes_per_pixel (e.g. stride=4 for a 64-wide 32bpp
-surface). The spice server rejects this via red_validate_surface(), but
-the return is void and QEMU unconditionally proceeds to set up the local
-rendering state. On the next display refresh, VNC or SDL reads width *
-byptes_pp per scanline from a region backed by only stride bytes per
-row, causing a host-side out-of-bounds read.
-
-Add three checks before creating the surface:
- - reject unknown surface formats
- - reject zero width or height
- - reject surfaces where abs(stride) < width * bytes_per_pixel
-

-Subject: [PATCH] hw/display/vga: fix text-mode OOB write after a graphics
- surface switch
-
-vga_draw_text() decides whether the console surface needs a resize from
-its geometry cache, but none of the cache terms observe the graphics
-renderer having replaced the console surface in between:
-
-- last_width/last_height are shared with vga_draw_graphic(), which
- stores them in pixels while the text path stores characters;
-- last_depth stays 0 for legacy (non-VBE) graphics modes, because
- vga_get_bpp() only reports a depth when VBE is enabled, so the
- "s->last_depth" term that normally forces a resize after a graphics
- frame does not fire.
-
-So a graphics frame that shrinks the console surface (e.g. 80x25
-pixels) followed by a text frame with matching character geometry
-(80x25 chars) skips the resize, and the glyph loop then paints
-width*cw x height*cheight pixels into the smaller surface, out of
-bounds, with guest-controlled (DAC palette) values, on every display
-refresh.
-
-Separate the geometry cache per renderer: text paths (vga_draw_text,
-vga_update_text, and the text handling in vga_invalidate_display /
-vga_common_reset) now only manipulate last_text_{width,height}, in
-characters; last_{width,height} become graphics-only, in pixels.
-Additionally, make the text path compare the pixel size it is about
-to paint against the console surface's actual dimensions. The
-surface check is the load-bearing term: caches in either unit cannot
-see the other renderer swapping the surface, the surface can.

-Subject: [PATCH] scsi-disk: fix out-of-bound read in WRITE SAME
-
-A guest with an attached scsi-hd can force QEMU's SCSI disk emulation
-to read roughly 60 KiB past the end of a heap buffer, copying that out
-of bounds host memory into the guest's own disk image.
-
-WRITE SAME computes the request transfer length at dev->blocksize
-when the request is prepared and sets cmd->xfer from dev->blocksize.
-scsi_disk_emulate_command() then uses cmd->xfer as the size of the
-request buffer.
-
-However, MODE SELECT can race with the WRITE SAME command and guest raise
-the logical block size to any value whose low bits fit 0xfe00, up to 65024.
-In the presence of this race, scsi_disk_emulate_write_same() will read
-from memory as many bytes as indicated by the *new* dev->blocksize,
-and write it to disk.
-
-The read length in WRITE SAME must be bounded by the buffer that was
-actually allocated, not by the mutable s->qdev.blocksize, so clamp the
-length used against inbuf to r->buflen. Re-validating req->cmd.xfer
-against the current block size would not work because the race is
-intrinsic in the SCSI protocol.
-
-I am not sure if this is exploitable with virtio-scsi and other SG-capable
-HBAs, because it should process the WRITE SAME input immediately,
-without letting the MODE SELECT command race with it.
-
-Fixes: 356c4c441ec ("scsi-disk: allow MODE SELECT block descriptor to set the block size", 2022-07-13)

-Subject: [PATCH] scsi: hide MODE SELECT block size change behind a quirk
-
-This is a dangerous operation in that the block size is not
-protected by a lock, but it can be written concurrently if
-you have a multi-queue virtio-scsi HBA. Put it behind a quirk
-that is only enabled by the Q800 machine, since the MODE
-SELECT feature was added for A/UX.

-Subject: [PATCH] io/channel-socket: do not treat a zero length write as an
- error
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-qio_channel_socket_writev() checks "ret <= 0" after sendmsg(). A zero
-length iovec is written successfully and returns 0, so the success
-falls into the errno switch, which acts on whatever the last failing
-syscall left in errno. A stale EAGAIN turns it into
-QIO_CHANNEL_ERR_BLOCK with errp untouched, and a caller which treats
-every negative return as fatal then passes a NULL Error to
-error_get_pretty(). The websocket handshake does exactly that, so an
-unauthenticated client crashes QEMU during the greeting.
-
-Returning 0 is safe for callers which loop until everything is
-written. qio_channel_writev_full_all() has no zero progress guard, but
-iov_copy() yields no entries for a zero length write, so that loop is
-never entered. A connected stream socket returns 0 only when there is
-nothing to send.
-
-The WIN32 implementation in the same file uses "ret < 0".
