CVE-2022-50142 intel_th: msu: Fix vmalloced buffers

In the Linux kernel, the following vulnerability has been resolved: intelth: msu: Fix vmalloced buffers After commit f5ff79fddf0e "dma-mapping: remove CONFIGDMAREMAP" there's a chance of DMA buffer getting allocated via vmalloc, which messes up the mmapping code: RIP: mscmmapfault intelthmsu Call...

CVE-2022-50142

CVE-2022-50142 : In the Linux kernel, the intel_th: msu component was fixed to account for DMA buffers that may be allocated via vmalloc() after the patch set removing CONFIG_DMA_REMAP, which could disrupt the mmapping code during faults (msc_mmap_fault). The described issue arises from a possibl...

CVE-2022-49983 udmabuf: Set the DMA mask for the udmabuf device (v2)

In the Linux kernel, the following vulnerability has been resolved: udmabuf: Set the DMA mask for the udmabuf device v2 If the DMA mask is not set explicitly, the following warning occurs when the userspace tries to access the dma-buf via the CPU as reported by syzbot here: WARNING: CPU: 1 PID:...

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 xsk: Fix corrupted packets for XDP_SHARED_UMEM

In the Linux kernel, the following vulnerability has been resolved: xsk: Fix corrupted packets for XDPSHAREDUMEM Fix an issue in XDPSHAREDUMEM mode together with aligned mode where packets are corrupted for the second and any further sockets bound to the same umem. In other words, this does not...

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...
