In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Fixed potential out-of-bounds accesses for Extigy and Mbox devices A bogus device can provide a bNumConfigurations value that exceeds the initial value used in usbgetconfiguration for allocating dev-config. This...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Validating UAC3 power domain descriptors as well. The UAC3 power domain descriptors also need to be verified using their variable bLength, in order to avoid unexpected OOB access attempts by malicious firmware...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Fixed potential memory leaks When the driver encounters -ENOMEM while allocating a URB or a buffer, it abends and proceeds to the error handling path, releasing all previously allocated resources. However, when...

Astra Linux – Vulnerability in alsa-lib

Versions of alsa-lib from 1.2.2 up to and including 1.2.15.2, prior to the release of 5f7fe33, contain a heap-based buffer overflow in the topology mixer control decoder. The tplgdecodecontrolmixer1 function reads the numchannels field from untrusted .tplg data and uses it as a loop bound without...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Properly terminating the timer upon removal The USB-audio MIDI code initializes the timer, but in a rare case, the driver might be freed without the disconnect call being made. This leaves the timer in an active...
