CVE-2026-64240 media: rc: igorplugusb: fix control request setup packet

In the Linux kernel, the following vulnerability has been resolved: media: rc: igorplugusb: fix control request setup packet Commit eac69475b01f "media: rc: igorplugusb: heed coherency rules" changed the control request storage from an embedded struct to an allocated pointer so it can obey DMA...

CVE-2026-64240

Summary of CVE-2026-64240 (Linux kernel, igorplugusb): The issue arises from the igorplugusb driver when the control request setup packet was moved to an allocated usb_ctrlrequest pointer for DMA coherency, but the code still passed ir->request to usb_fill_control_urb(), causing the URB to poi...

CVE-2026-64234

The CVE-2026-64234 entry concerns the Linux kernel tty/serial driver pch_uart. The root cause is a missing check of the return value from dma_alloc_coherent(), which could yield a NULL pointer, triggering a crash in dma_handle_rx(). The fix adds a guard for dma_alloc_coherent() failure and ensure...

CVE-2026-64221 spi: ti-qspi: fix use-after-free after DMA setup failure

In the Linux kernel, the following vulnerability has been resolved: spi: ti-qspi: fix use-after-free after DMA setup failure The driver falls back to PIO mode if DMA setup fails during probe. Make sure to clear the DMA channel pointer also if buffer allocation fails to avoid passing a pointer to...

CVE-2026-64221

The CVE-2026-64221 entry concerns the Linux kernel SPI TI-QSPI driver. The flaw is a use-after-free after DMA setup failure: during probe, the driver falls back to PIO if DMA setup fails, and the fix ensures the DMA channel pointer is cleared if buffer allocation fails to avoid passing a released...
