CVE-2026-31701

In CVE-2026-31701, the Linux kernel ALSA caiaq driver (USB audio) stored a pointer to the parent usb_device without a reference. The snd_usb_caiaq_card_free() path can run after the USB device is disconnected, dereferencing freed memory (use-after-free). The fix is to take a reference on the USB ...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from missing index handling of the SPDIF1 DAIO type in the ALSA ctxfi driver, which could lead to out-of-bounds...

freerdp: FreeRDP: Denial of Service via use-after-free in AUDIN format renegotiation

A use after free flaw was found in FreeRDP. AUDIN format renegotiation frees the active format list while the capture thread continues using audin-format, leading to a use after free in audioformatcompatible. A malicious server can trigger a client‑side heap use after free causing a crash...

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...
