CVE-2025-70292 is an integer-overflow vulnerability in Denx U-Boot's SquashFS handling, affecting sqfs_concat_tokens in the SquashFS filesystem implementation. Manipulated token lists cause sqfs_get_tokens_length() to overflow while calculating the aggregate token length. The resulting truncated size causes an undersized heap allocation, which is subsequently overwritten by strcpy() during token concatenation. U-Boot releases through v2026.01-rc4 are affected.
