CVE-2026-99127 Oct 28, 2026 Source: Vendor
In the Linux kernel, the following vulnerability has been resolved:
page_pool: keep frag_offset aligned for odd-sized requests
page_pool_alloc_frag_netmem() rounds the requested fragment size with
size = ALIGN(size, dma_get_cache_alignment());
dma_get_cache_alignment() returns 1 unless the architecture defines
ARCH_DMA_MINALIGN, which DMA-coherent architectures such as x86 do not.
There the ALIGN() is a no-op and pool->frag_offset advances by the raw,
unrounded size.
