CVE-2026-90023 usb: gadget: f_mass_storage: fix null pointer dereference in fsg_common_set_num_buffers()

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: fmassstorage: fix null pointer dereference in fsgcommonsetnumbuffers Previously fsgnumbuffersvalidate was removed as it was not necessary due to Kconfig setting the limits for n from 2 to 256 with default as 2...

CVE-2026-90023

CVE-2026-90023 is a null pointer dereference in the Linux kernel USB gadget f_mass_storage driver, specifically in fsg_common_set_num_buffers(). The root cause is that the earlier removal of fsg_num_buffers_validate() relied on Kconfig limits (2–256) for the buffer count n, but a user can write p...

CVE-2026-90020

CVE-2026-90020 affects the Linux kernel USB gadget subsystem. The vulnerability is a race condition in gadget_dev_ioctl(): the function reads dev->gadget before acquiring dev->lock, but checks dev->state only after acquiring the lock. A concurrent bind can change the device state between...

CVE-2026-90019

CVE-2026-90019 affects the Linux kernel USB gadget subsystem. In the UVC function implementation, usb_put_function_instance() dereferences fi->fd to retrieve the module reference in the uvc_alloc_inst() error path. However, fd is not allocated until later in try_get_usb_function_instance(), so...

CVE-2026-90012 spi: Fix DMA mapping ownership on partial map failure

In the Linux kernel, the following vulnerability has been resolved: spi: Fix DMA mapping ownership on partial map failure If RX mapping fails after TX mapping succeeds, spimapmsg unmaps TX but leaves txsgmapped set. If TX mapping fails on a later transfer, mappings created for earlier transfers...

CVE-2026-90012

CVE-2026-90012 is a Linux kernel SPI bug in DMA mapping ownership on partial map failure. When RX mapping fails after TX mapping succeeds, __spi_map_msg() unmaps TX but leaves tx_sg_mapped set, and cur_{tx,rx}_dma_dev are not yet updated. The subsequent spi_unmap_msg() can then double-free a TX m...
