kernel: Linux kernel: Denial of Service via out-of-bounds read in USB configuration parsing

A flaw was found in the Linux kernel's USB core configuration parsing. Specifically, the usbparsessendpointcompanion function incorrectly checks the descriptor type before its length, which can lead to reading data beyond the intended buffer. This out-of-bounds read vulnerability could allow a...

CVE-2026-23115

In the Linux kernel, the following vulnerability has been resolved: serial: Fix not set tty-port race condition Revert commit bfc467db60b7 "serial: remove redundant ttyportlinkdevice" because the ttyportlinkdevice is not redundant: the tty-port has to be confured before we call uartconfigureport,...

kernel: Linux kernel ALSA USB audio driver: Buffer overflow leading to information disclosure and denial of service

A flaw was found in the ALSA USB audio driver of the Linux kernel. This vulnerability, a buffer overflow, occurs when the size of the Pulse-Code Modulation PCM stream data packets exceeds the maximum allowed by the USB descriptor. A local attacker could exploit this by providing specially crafted...
