CVE-2022-49592

CVE-2022-49592 affects the Linux kernel driver net/stmmac: a left-shift overflow in MTL_RXQ_DMA_MAP1 occurs when the number of TX/RX queues exceeds four, due to a 32‑bit mask calculation. UBSAN reports show a shift-out-of-bounds during UBSAN checks, leading to a potential warning path in dwmac4_c...

CVE-2022-49569

CVE-2022-49569 affects the bcm2835 SPI driver in the Linux kernel. When an IRQ-based transfer times out, bcm2835_spi_handle_err() could dereference ctlr->dma_tx/ctlr->dma_rx if DMA pointers are not set, due to the removal of the dma_pending flag. A fix was implemented to check that ctlr-&gt...

CVE-2022-49524

The Linux kernel contains a use-after-free vulnerability in the media: pci: cx23885 driver. The issue is caused by improper error handling in the cx23885_initdev() function; specifically, the driver fails to release i2c-related resources initialized in cx23885_dev_setup() if the subsequent dma_se...

CVE-2022-49522

CVE-2022-49522 concerns a Linux kernel MMC driver issue (mmc: jz4740) where DMA maps could exceed the DMA engine’s capabilities. The root cause is not a research-level flaw but an inadequate limit on the maximum segment size for DMA data transfers. The fix enforces DMA engine limits on the jz4740...

CVE-2022-49522

In the Linux kernel, the following vulnerability has been resolved: mmc: jz4740: Apply DMA engine limits to maximum segment size Do what is done in other DMA-enabled MMC host drivers cf. host/mmci.c and limit the maximum segment size based on the DMA engine's capabilities. This is needed to avoid...

CVE-2022-49500

CVE-2022-49500 concerns the wl1251 DMA memory handling in the Linux kernel. With the switch to vmap’ed stacks, stack parameters can no longer be used for DMA, which could trigger a kernel panic at multiple wl1251 locations (e.g., via SDIO), rendering devices like OpenPandora unusable. The fixed a...

CVE-2022-49452

The CVE-2022-49452 issue concerns the Linux kernel DPAA2 Ethernet driver (dpaa2-eth). The vulnerability arises when the virtual address is retrieved after DMA unmapped in TSO path, leading to an invalid address being used in kfree. A fix was implemented to call dpaa2_iova_to_virt() before the dma...
