CVE-2024-57838

Stack depot exhaustion via unmarked IRQ entries

Published Jan 11, 2025 · Updated May 11, 2026

Resource exhaustion in the s390 Linux kernel allows local users to deplete the stack depot through asynchronous interrupts. Because s390 leaves .irqentry.text empty, in_irqentry_text() fails to truncate IRQ stack traces, so stacks from randomly interrupted sites evade de-duplication. Exposure requires PREEMPT and KASAN to be enabled; exhaustion produces capacity-limit warnings and prevents additional stack traces from being saved.
