Process denial of service
Published Jun 25, 2026 · Updated Jun 25, 2026
Denial of service in relibc commit 61f42d allows attackers to disrupt a calling process via crafted rwlock attribute input. The record names pthread_rwlockattr_setpshared() but does not disclose which value the function mishandles or whether the process hangs or crashes. Reachability requires attacker-controlled data to reach this library entry point through a consuming application.
