A flaw was found in the Linux kernel's Reliable Datagram Sockets (RDS) subsystem. When memory region mapping fails during InfiniBand operations, the kernel can retain a stale reference to memory buffers that have already been released. A local attacker could exploit this flaw to trigger a use-after-free condition, potentially leading to local privilege escalation or a denial of service through a system crash.
