CVE-2026-23475

A flaw was found in the Linux kernel's Serial Peripheral Interface SPI component. The system's per-CPU statistics for the SPI controller were not allocated until after the controller was registered. This created a window where a local user or process could access system files sysfs attributes...

CVE-2026-23472

A flaw was found in the Linux kernel's serial core component. An inconsistency between the uartwriteroom and uartwrite functions, specifically when handling PORTUNKNOWN serial ports with a NULL transmit buffer, can lead to an infinite loop. This allows a local user or process to trigger a system...

CVE-2026-23472

Summary: A Linux kernel vulnerability in the serial core (CVE-2026-23472) arises when handling PORT_UNKNOWN with a NULL transmit buffer, where uart_write_room() can report available space inconsistently with uart_write() , causing an infinite loop in drivers that rely on tty_write_room() to decid...

In the Linux kernel, the following vulnerability has been resolved: net: usb: cdcncm: add ndpoffset to NDP16 nframes bounds check cdcncmrxverifyndp16 validates that the NDP header and its DPE entries fit within the skb. The first check correctly accounts for ndpoffset: if ndpoffset + sizeofstruct...

CVE-2026-23447

The CVE-2026-23447 issue concerns the Linux kernel USB CDC NCM driver (cdc_ncm). The root cause is a bounds-check failure in handling NDP32 frames where the DPE array size is not correctly validated against the skb length due to neglecting ndpoffset, allowing out-of-bounds reads when an NDP32 sit...

CVE-2026-23446 net: usb: aqc111: Do not perform PM inside suspend callback

In the Linux kernel, the following vulnerability has been resolved: net: usb: aqc111: Do not perform PM inside suspend callback syzbot reports "task hung in rpmresume" This is caused by aqc111suspend calling the PM variant of its writecmd routine. The simplified call trace looks like this:...

Electron: USB device selection not validated against filtered device list

Impact The select-usb-device event callback did not validate the chosen device ID against the filtered list that was presented to the handler. An app whose handler could be influenced to select a device ID outside the filtered set would grant access to a device that did not match the renderer's...
