CVE-2022-49983

The issue CVE-2022-49983 affects the Linux kernel udmabuf driver. If the udmabuf DMA mask is not set explicitly, userspace DMA-BUF access via the CPU can trigger a warning in dma_map_sg_attrs (kernel/dma/mapping.c) during dma-buf CPU access flows (as shown in the stack trace). The vulnerability i...

CVE-2022-49972

In CVE-2022-49972, the Linux kernel vulnerability concerns XDP_SHARED_UMEM mode (with aligned mode) where packets become corrupted for the second and subsequent sockets bound to the same umem; the first socket is unaffected. The root cause was that DMA addresses for the pre-populated xsk buffer p...

CVE-2022-49935 dma-buf/dma-resv: check if the new fence is really later

In the Linux kernel, the following vulnerability has been resolved: dma-buf/dma-resv: check if the new fence is really later Previously when we added a fence to a dmaresv object we always assumed the the newer than all the existing fences. With Jason's work to add an UAPI to explicit export/impor...

CVE-2022-49935

CVE-2022-49935 affects the Linux kernel’s dma-buf/dma-resv code. The vulnerability arises from assuming a newly added fence is newer than all existing fences; with the explicit UAPI export/import, this assumption was removed, creating a path where userspace could force the kernel into a use-after...
