CVE-2026-53159

In the Linux kernel, the following vulnerability has been resolved: misc: fastrpc: fix DMA address corruption due to findvma misuse fastrpcgetargs uses findvma 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,...

CVE-2026-53159

CVE-2026-53159 (Linux kernel) : The vulnerability is in misc: fastrpc where fastrpc_get_args() uses find_vma() to locate the VMA for a user pointer and compute a DMA address. If the address lies in a gap before the returned VMA, (ptr & PAGE_MASK) - vma->vm_start underflows, corrupting the DMA ...

CVE-2024-56611 mm/mempolicy: fix migrate_to_node() assuming there is at least one VMA in a MM

In the Linux kernel, the following vulnerability has been resolved: mm/mempolicy: fix migratetonode assuming there is at least one VMA in a MM We currently assume that there is at least one VMA in a MM, which isn't true. So we might end up having findvma return NULL, to then de-reference NULL. So...
