CVE-2026-53159 Details
Description
In the Linux kernel, the following vulnerability has been resolved: misc: fastrpc: fix DMA address corruption due to find_vma misuse fastrpc_get_args() uses find_vma() to look up the VMA for a user-provided pointer and compute a DMA address offset. When the address falls in a gap before the returned VMA, (ptr & PAGE_MASK) - vma->vm_start underflows, corrupting the DMA address sent to the DSP. Replace find_vma() with vma_lookup(), which returns NULL when the address is not contained within any VMA.
A vulnerability in the Linux kernel's fastrpc implementation can lead to DMA address corruption. The issue arises in the fastrpc_get_args() function, which uses find_vma() to locate the Virtual Memory Area (VMA) for a user-supplied pointer and calculate a DMA address offset. If the pointer falls into a gap before the identified VMA, the calculation underflows, distorting the DMA address sent to the Digital Signal Processor (DSP). This vulnerability affects the Linux kernel stable tree.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. The official Linux kernel Git repository can be used to download the patched version.
