OESA-2026-4861: libsndfile security update
Libsndfile is a C library for reading and writing files containing sampled sound such as MS Windows WAV and the Apple/SGI AIFF format through one standard library interface. Security Fix(es):
A vulnerability was found in libsndfile up to 1.2.2. This issue affects the function wavlikesubchunkparse of the file src/wavlike.c of the component WAV Parsing. Performing a manipulation results in use of uninitialized variable. Remote exploitation of the attack is possible. The exploit has been made public and could be used. The project was informed of the problem early through an issue report but has not responded yet.(CVE-2026-109828)

Event History
Frequently Asked Questions
Who is exposed to this issue?
Systems using openEuler's libsndfile package may be exposed when they process WAV files. The affected code is in the WAV parsing component, so exposure depends on whether an application accepts or opens attacker-controlled WAV content.
What does an attacker need to exploit it?
The issue is remotely exploitable and requires no privileges, but user interaction is required. An attacker would need to induce processing of a manipulated WAV file through software that uses libsndfile.
Is public exploit information available?
Yes. The exploit has been made public and could be used.
How can I tell whether my environment is affected?
Check whether the system uses the openEuler libsndfile package and whether its installed libsndfile version is up to 1.2.2. Also identify applications that use the library to parse WAV files, particularly where those files can originate from untrusted sources.
