Kerentanan Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') pada canonical ubuntu linux. Skor CVSS 3.1 4.7 (Medium) menurut NVD.

Deskripsi (NVD)

An Ubuntu-specific patch in PulseAudio created a race condition where the snap policy module would fail to identify a client connection from a snap as coming from a snap if SCM_CREDENTIALS were missing, allowing the snap to connect to PulseAudio without proper confinement. This could be exploited by an attacker to expose sensitive information. Fixed in 1:13.99.3-1ubuntu2, 1:13.99.2-1ubuntu2.1, 1:13.99.1-1ubuntu3.8, 1:11.1-1ubuntu7.11, and 1:8.0-0ubuntu3.15.
