CVE-2026-74635

CVE-2026-74635 is an out-of-bounds read in the Linux kernel's fbdev subsystem, specifically in bit_cursor() (drivers/video/fbdev/core/bitblit.c). The glyph index is derived from the screen buffer via scr_readw() and can exceed the current font's glyph count when an arbitrary 16-bit value is writt...
