CVE-2026-43469

A flaw was found in the Linux kernel's xprtrdma component. This vulnerability occurs when the rpcrdma_post_recvs() function fails to create a work request or exits prematurely, leading to the re_receiving counter not being decremented. This improper resource handling can cause the system to hang indefinitely, resulting in a Denial of Service (DoS) for affected systems, particularly under high memory pressure.

Red Hat acknowledges the upstream Linux kernel correction for «xprtrdma» as described in COMMENT_ZERO. Fixes are delivered through standard kernel errata for supported products. Operational exposure depends on whether this subsystem or driver is active in your configuration.
