CVE-2026-43061

CVE-2026-43061 (Linux kernel): The serial8250 TX DMA deadlock was fixed. The root cause was that dmaengine_terminate_async did not guarantee the __dma_tx_complete callback would run, and that callback is the only place where dma->tx_running is cleared. If a TX DMA transaction is canceled and t...

CVE-2026-31768

A flaw was found in the Linux kernel, specifically within the ti-adc161s626 Analog-to-Digital Converter ADC driver. This vulnerability arises from the use of non-Direct Memory Access DMA-safe stack memory for Serial Peripheral Interface SPI read operations. An attacker with local access could...

CVE-2026-31760

A flaw was found in the Linux kernel's gpib: lpvousb driver. This memory leak vulnerability occurs when the driver fails to release references to USB devices upon disconnection. A local user with the ability to connect and disconnect USB devices could repeatedly trigger this flaw, leading to...

CVE-2026-31759

A flaw was found in the Linux kernel's USB ULPI UTMI+ Low Pin Interface driver. An error in the ulpiregisterinterface function's cleanup path can lead to a double free vulnerability. This occurs when deviceregister fails, causing the ulpi structure to be freed twice. A local attacker could...

CVE-2026-31727

A flaw was found in the Linux kernel's USB gadget subsystem, specifically within the uether module. A local user can exploit this vulnerability by using a userspace tool to query a USB gadget interface during a specific detached state. This action can trigger a NULL pointer dereference, potential...

CVE-2026-31701

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA caiaq driver. This vulnerability arises from improper handling of Universal Serial Bus USB device references. When a USB device is disconnected, the driver may attempt to access memory that has already been freed, a...

CVE-2026-31757

In the Linux kernel, the following vulnerability has been resolved: usb: misc: usbio: Fix URB memory leak on submit failure When usbsubmiturb fails in usbioprobe, the previously allocated URB is never freed, causing a memory leak. Fix this by jumping to errfreeurb label to properly release the UR...
