kernel: ALSA: usb-audio: Add sanity check for OOB writes at silencing

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture USB audio subsystem. An inconsistency in how USB audio playback and capture streams are handled can lead to an out-of-bounds write to a memory buffer. This can result in a system crash, causing a denial of service for a...

DEBIAN-CVE-2026-49346

libde265 is an open source implementation of the h.265 video codec. Prior to version 1.1.0, a crafted H.265 bitstream with large SPS dimensions and 16-bit bit depth causes a signed integer overflow in de265imagegetbuffer libde265/image.cc:128. The overflow wraps the plane allocation size to a sma...

py7zr: O(n^2) algorithmic complexity DoS in PackInfo._read()

Summary PackInfo.read uses an On^2 cumulative sum pattern where numstreams is read directly from the archive header. A crafted .7z archive with a large numstreams value causes excessive CPU consumption during SevenZipFile.init — no extraction is needed. A 50 KB archive takes 7 seconds of CPU time...

Inefficient Algorithmic Complexity

Overview py7zr is a Pure python 7-zip library Affected versions of this package are vulnerable to Inefficient Algorithmic Complexity through the PackInfo.read function. An attacker can cause excessive CPU consumption by providing a crafted archive with a large number of streams, leading to...
