Created: Dec 8, 2025 Updated: Jun 1, 2026

Resolved Date: May 25, 2026

Found In Version: 10.22.33.1

Fix Version: 10.22.33.24

Severity: Standard

Applicable for: Wind River Linux LTS 22

Component/s: Kernel

Description

In the Linux kernel, the following vulnerability has been resolved: fbdev: bitblit: bound-check glyph index in bit_putcs* bit_putcs_aligned()/unaligned() derived the glyph pointer from the character value masked by 0xff/0x1ff, which may exceed the actual font's glyph count and read past the end of the built-in font array. Clamp the index to the actual glyph count before computing the address. This fixes a global out-of-bounds read reported by syzbot.
