AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Local socket access inherently requires an active user session (AV:L, PR:L); purely a DoS crash with no confidentiality or integrity impact (C:N/I:N).

Multiple unbounded alloca() calls in the PulseAudio protocol server.
AnalysisAI
Stack exhaustion via multiple unbounded alloca() calls in the PulseAudio protocol server on Red Hat Enterprise Linux 8, 9, and 10 allows a local low-privileged attacker to crash the audio daemon, resulting in denial of service. The root cause (CWE-770) is the absence of size validation on attacker-controlled protocol parameters before passing them to alloca(), a stack-based allocator with no OS-enforced ceiling. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a local user session on the target RHEL system with the ability to connect to the PulseAudio protocol server socket (CVSS AV:L/PR:L confirmed). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H (5.5 Medium) accurately characterizes the constrained real-world risk: exploitation is strictly local, requires only a standard user session, and produces no confidentiality or integrity impact - only a crash of the audio daemon. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A local attacker with a standard user account on a multi-user RHEL desktop system connects to the PulseAudio protocol socket and sends a crafted request containing an oversized length field. The daemon passes this unsanitized value to alloca(), instantly exhausting the thread's stack space, triggering a stack overflow that terminates the PulseAudio process and denies audio service to all active users. … |
| Remediation | No exact patched PulseAudio package version is identified in the available references - patch availability and specific fix versions must be confirmed directly via the Red Hat security advisory at https://access.redhat.com/security/cve/CVE-2026-14330 and the Bugzilla report at https://bugzilla.redhat.com/show_bug.cgi?id=2495907; apply the vendor-released RPM update as soon as it becomes available via standard RHEL channels (yum/dnf update pulseaudio). … Detailed patch versions, workarounds, and compensating controls in full report. |
