CVE-2026-89545 sunrpc: defer rq_argp and rq_resp free until after RCU grace period
In the Linux kernel, the following vulnerability has been resolved: sunrpc: defer rqargp and rqresp free until after RCU grace period svcrqstfree frees rqstp-rqargp and rqstp-rqresp synchronously via kfree, but defers the rqstp struct free via kfreercu. After svcexitthread calls listdelrcu and...
CVE-2026-89545 sunrpc: defer rq_argp and rq_resp free until after RCU grace period
In the Linux kernel, the following vulnerability has been resolved: sunrpc: defer rqargp and rqresp free until after RCU grace period svcrqstfree frees rqstp-rqargp and rqstp-rqresp synchronously via kfree, but defers the rqstp struct free via kfreercu. After svcexitthread calls listdelrcu and...
CVE-2026-89546
CVE-2026-89546 affects the Linux kernel's SUNRPC subsystem, specifically the NFS callback service. A race condition during service teardown can cause two distinct issues: a resource leak when xprt_enqueue_bc_request() returns without enqueuing or freeing a committed request (and its associated xp...

CVE-2026-89545
CVE-2026-89545 is a use-after-free in the Linux kernel's sunrpc subsystem. The function svc_rqst_free() frees rqstp->rq_argp and rqstp->rq_resp synchronously via kfree(), while the parent rqstp struct is deferred via kfree_rcu(). After svc_exit_thread() removes the thread from the RCU list,...

In the Linux kernel, the following vulnerability has been resolved: sunrpc: fix use-after-free in rpcclnthandleevent and rpcclntremovepipedir Normal client creation goes through rpcsetuppipedir, which records clnt-pipefssb, but the mount-event path in rpcclnthandleevent calls rpcsetuppipedirsb...
CVE-2026-89543
CVE-2026-89543 is a use-after-free vulnerability in the Linux kernel's sunrpc subsystem. The root cause is that the mount-event path in __rpc_clnt_handle_event() calls rpc_setup_pipedir_sb() without refreshing the clnt->pipefs_sb field, and the umount path removes the directory without clearin...
