Title
fbdev: bitblit: bound-check glyph index in bit_cursor()
Summary
In the Linux kernel, the following vulnerability has been resolved:
fbdev: bitblit: bound-check glyph index in bit_cursor()
bit_cursor() fetches the glyph under the cursor with
c = scr_readw(vc_pos);
src = vc_font.data + ((c & charmask) * w * height);
where charmask is 0x1ff when vc_hi_font_mask is set. The screen buffer
value comes directly from scr_readw() and may be larger than the current
font's glyph count.
Syzkaller triggers this via vcs_write(). The Call Trace shows
vcs_write() in vc_screen.c writing an arbitrary 16-bit value with
writev() to /dev/vcsa, which vcs_write_buf() in vc_screen.c stores via
vcs_scr_writew() without checking charcount. The stored value is later
read in bit_cursor() in bitblit.c.
When the font is changed from a font with 512 glyphs to a font with
256 glyphs, the screen buffer can retain characters with the high
bit set from the previous mode, which could also produce the same
out-of-bounds access.
BUG: KASAN: global-out-of-bounds in soft_cursor+0x378/0x6bc drivers/video/fbdev/core/softcursor.c:70
Read of size 16 at addr ffff800086c57970
Call Trace:
soft_cursor+0x378/0x6bc drivers/video/fbdev/core/softcursor.c:70

bit_putcs_aligned() and bit_putcs_unaligned() already clamp the glyph
index to vc_font.charcount. Apply the same clamp in bit_cursor() after
extracting the attribute and masking, before indexing fontdata.
The fix completes the bounds checking started in commit 18c4ef4e765a
("fbdev: bitblit: bound-check glyph index in bit_putcs*"), which missed
the cursor path.
This change should be safe because the clamp reuses the existing
contract from fbcon: charcount is maintained under console_lock in
con_font_set() and fbcon_font_set(), and hi_font_mask is cleared when
switching from 512 to 256 glyphs. When stale screen data with high bits
remains after a font switch, or when vcs_write() stores an arbitrary
value, clamping the index to 0 prevents the out-of-bounds read without
changing cursor semantics — the same fallback bit_putcs uses.

The stored value is later\\nread in bit_cursor() in bitblit.c.\\n\\nWhen the font is changed from a font with 512 glyphs to a font with\\n256 glyphs, the screen buffer can retain characters with the high\\nbit set from the previous mode, which could also produce the same\\nout-of-bounds access.\\n\\n BUG: KASAN: global-out-of-bounds in soft_cursor+0x378/0x6bc drivers/video/fbdev/core/softcursor.c:70\\n Read of size 16 at addr ffff800086c57970\\n\\n Call Trace:\\n soft_cursor+0x378/0x6bc drivers/video/fbdev/core/softcursor.c:70\\n bit_cursor+0xa90/0x1108 drivers/video/fbdev/core/bitblit.c:365\\n fbcon_cursor+0x344/0x498 drivers/video/fbdev/core/fbcon.c:1427\\n hide_cursor+0xdc/0x2d0 drivers/tty/vt/vt.c:883\\n update_region+0x100/0x18c drivers/tty/vt/vt.c:669\\n vcs_write+0x8ec/0xaf0 drivers/tty/vt/vc_screen.c:685\\n\\nbit_putcs_aligned() and bit_putcs_unaligned() already clamp the glyph\\nindex to vc_font.charcount.

When stale screen data with high bits\\nremains after a font switch, or when vcs_write() stores an arbitrary\\nvalue, clamping the index to 0 prevents the out-of-bounds read without\\nchanging cursor semantics \u2014 the same fallback bit_putcs uses.\"}],\"affected\":[{\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"affectedData\":[{\"vendor\":\"Linux\",\"product\":\"Linux\",\"defaultStatus\":\"unaffected\",\"programFiles\":[\"drivers/video/fbdev/core/bitblit.c\"],\"repo\":\"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\"versions\":[{\"version\":\"0998a6cb232674408a03e8561dc15aa266b2f53b\",\"lessThan\":\"250159ace2dc53c1bdad267aa8da51b638748700\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"db5c9a162d2f42bcc842b76b3d935dcc050a0eec\",\"lessThan\":\"46336f476484f36145e5117e72d7b590f47433ee\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"c12003bf91fdff381c55ef54fef3e961a5af2545\",\"lessThan\":\"bf750cfeacf4e47ac72dadc7f05839696efb8576\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"9ba1a7802ca9a2590cef95b253e6526f4364477f\",\"lessThan\":\"94134d70abf9273b70499d97d0adc9185ef21091\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"901f44227072be60812fe8083e83e1533c04eed1\",\"lessThan\":\"c1e7351767dd30fc574395c82121e4c67b882da3\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"18c4ef4e765a798b47980555ed665d78b71aeadf\",\"lessThan\":\"bc9db0d879c655d5dfd8add32fd60f13e65d132c\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"18c4ef4e765a798b47980555ed665d78b71aeadf\",\"lessThan\":\"9ea879862e66e354e616028c31b39aa3eb6d35d8\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"18c4ef4e765a798b47980555ed665d78b71aeadf\",\"lessThan\":\"e033cbf3975a8465f879ebd5989dc35b04423a4d\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"a10cede006f9614b465cf25609a8753efbfd45cc\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"efaf89a75a29b2d179bf4fe63ca62852e93ad620\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"5.10.247\",\"lessThan\":\"5.10.265\",\"versionType\":\"semver\",\"status\":\"affected\"},{\"version\":\"5.15.197\",\"lessThan\":\"5.15.216\",\"versionType\":\"semver\",\"status\":\"affected\"},{\"version\":\"6.1.159\",\"lessThan\":\"6.1.183\",\"versionType\":\"semver\",\"status\":\"affected\"},{\"version\":\"6.6.117\",\"lessThan\":\"6.6.152\",\"versionType\":\"semver\",\"status\":\"affected\"},{\"version\":\"6.12.58\",\"lessThan\":\"6.12.104\",\"versionType\":\"semver\",\"status\":\"affected\"},{\"version\":\"5.4.302\",\"lessThan\":\"5.5\",\"versionType\":\"semver\",\"status\":\"affected\"},{\"version\":\"6.17.8\",\"lessThan\":\"6.18\",\"versionType\":\"semver\",\"status\":\"affected\"}]},{\"vendor\":\"Linux\",\"product\":\"Linux\",\"defaultStatus\":\"affected\",\"programFiles\":[\"drivers/video/fbdev/core/bitblit.c\"],\"repo\":\"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\"versions\":[{\"version\":\"6.18\",\"status\":\"affected\"},{\"version\":\"0\",\"lessThan\":\"6.18\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"5.10.265\",\"lessThanOrEqual\":\"5.10.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"5.15.216\",\"lessThanOrEqual\":\"5.15.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.1.183\",\"lessThanOrEqual\":\"6.1.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.6.152\",\"lessThanOrEqual\":\"6.6.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.12.104\",\"lessThanOrEqual\":\"6.12.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.18.45\",\"lessThanOrEqual\":\"6.18.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"7.1.9\",\"lessThanOrEqual\":\"7.1.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"7.2\",\"lessThanOrEqual\":\"*\",\"versionType\":\"original_commit_for_fix\",\"status\":\"unaffected\"}]}]}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"type\":\"Secondary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H\",\"baseScore\":7.8,\"baseSeverity\":\"HIGH\",\"attackVector\":\"LOCAL\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"HIGH\",\"integrityImpact\":\"HIGH\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":1.8,\"impactScore\":5.9}]},\"references\":[{\"url\":\"https://git.kernel.org/stable/c/250159ace2dc53c1bdad267aa8da51b638748700\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/46336f476484f36145e5117e72d7b590f47433ee\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/94134d70abf9273b70499d97d0adc9185ef21091\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/9ea879862e66e354e616028c31b39aa3eb6d35d8\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/bc9db0d879c655d5df
