kernel: i40e: Fix DMA mappings leak

A DMA mapping leak vulnerability was found in the Intel i40e network driver in the Linux kernel. During reallocation of RX buffers when changing ring parameters via ethtool, DMA mappings are not properly cleaned up before creating new ones. Repeated ring size changes can exhaust DMA resources,...

kernel: dmaengine: Fix double increment of client_count in dma_chan_get()

In the Linux kernel, the following vulnerability has been resolved: dmaengine: Fix double increment of clientcount in dmachanget The first time dmachanget is called for a channel the channel clientcount is incorrectly incremented twice for public channels, first in balancerefcount, and again prio...

kernel: net: stmmac: fix dma queue left shift overflow issue

In the Linux kernel, the following vulnerability has been resolved: net: stmmac: fix dma queue left shift overflow issue When queue number is 4, left shift overflows due to 32 bits integer variable. Mask calculation is wrong for MTLRXQDMAMAP1. If CONFIGUBSAN is enabled, kernel dumps below warning...

kernel: 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:...

kernel: Double-free in split_2MB_gtt_entry when function intel_gvt_dma_map_guest_page failed

A double-free memory flaw was found in the Linux kernel. The Intel GVT-g graphics driver triggers VGA card system resource overload, causing a fail in the intelgvtdmamapguestpage function. This issue could allow a local user to crash the system...

An out-of-bounds write vulnerability was found in the Linux kernel's SLIMpro I2C device driver. The userspace "data->block[0]" variable was not capped to a number between 0-255 and was used as the size of a memcpy possibly writing beyond the end of dma_buffer. This flaw could allow a local privileged user to crash the system or potentially achieve code execution.
