CVE-2026-52964

Summary of CVE-2026-52964 : A flaw in the Linux kernel’s ALSA USB-audio path (USB MIDI 2.0 endpoint parser) fails to validate descriptor lengths for the MIDI 2.0 endpoint, allowing a malformed device to cause out-of-bounds reads on baAssoGrpTrmBlkID[] due to walking endpoint extras before verifyi...

CVE-2026-52963 ALSA: usb-audio: Bound MIDI endpoint descriptor scans

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Bound MIDI endpoint descriptor scans sndusbmidigetmsinfo validates the internal MIDIStreaming endpoint descriptor size before using baAssocJackID, but the descriptor walker can still return a class-specific...

CVE-2026-52963

CVE-2026-52963 affects the Linux kernel ALSA usb-audio code path, specifically the MIDI endpoint handling in snd_usbmidi_get_ms_info. The vulnerability arises when the descriptor walker returns a class-specific MIDI endpoint with bLength larger than the remaining bytes in the endpoint-extra scan,...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: ALSA: dice: fixed a buffer overflow in detectstreamformats The function detectstreamformats reads the streamcount value directly from a FireWire device without validating it. This can lead to out-of-bounds writes when a malicious...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: ALSA: firewire-motu – fixed a buffer overflow issue in the hwdep read function for DSP events. The DSP event handling code in hwdepread could write more bytes to the user buffer than requested, especially when the user provided a...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: ALSA: aloop – Fixedracy access during PCM trigger events The PCM trigger callback of the aloop driver attempts to check the PCM state and stop the stream of the tied substream in the corresponding cable. Since both the check and...

Astra Linux – Vulnerability in Qemu

An integer overflow vulnerability was discovered in the virtio-snd device through PCMINFO requests from the guest. A malicious guest can provide out-of-bounds stream counts, potentially leading to unbounded memory allocation on the host and a denial of service condition...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in QEMU. When reading input audio from the virtio-snd device’s input callback, the virtiosndpcmincb function did not check whether the iov could accommodate the data buffer, potentially leading to a heap out-of-bounds write. This issue persists due to an incomplete fix for...
