CVE-2022-49661

Affected component: Linux kernel, gs_usb driver (USB CAN adapter). Issue: memory leak in gs_usb_open/close where RX URBs allocated with usb_alloc_coherent() were not freed by usb_kill_anchored_urbs() and DMA memory leaked. Root cause: improper freeing pattern; the fix explicitly frees RX URBs and...

CVE-2022-49592 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...

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

CVE-2022-49524 relates to the Linux kernel media driver for cx23885 (pci) where the error path in cx23885_initdev() did not release I2C-related resources when dma_set_mask() failed. The concrete details describe that a failed dma_set_mask() leads to a use-after-free in __process_removed_driver, t...

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...
