The memory allocated for the copy needs to be rounded to DMA cache alignment, as otherwise the hashed key may corrupt neighbouring memory. The copying is performed using kmemdup, however this leads to an overflow: reading more bytes (aligned_len - keylen) from the keylen source buffer. Fix this by replacing kmemdup with kmalloc, followed by memcpy. Join the discussion | GCVE Database | 05/08/2026, 14:16:00 UTC Added: 07/17/2026, 10:24:50 UTC |
