Red Hat Security Advisory: kernel-rt security update
Notes
Topic
An update for kernel-rt is now available for Red Hat Enterprise Linux 9.2 Update Services for SAP Solutions.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.
Security Fix(es):
* kernel: nfsd: handle get_client_locked() failure in nfsd4_setclientid_confirm() (CVE-2025-38724)
* kernel: smb: client: fix race with concurrent opens in rename(2) (CVE-2025-39825)
* kernel: can: j1939: implement NETDEV_UNREGISTER notification handler (CVE-2025-39925)
* kernel: Bluetooth: hci_conn: Fix crash on hci_create_cis_sync (CVE-2022-50447)
* kernel: RDMA/rxe: Fix incomplete state save in rxe_requester (CVE-2023-53539)
* kernel: NFSD: Avoid calling OPDESC() with ops->opnum == OP_ILLEGAL (CVE-2023-53680)
* kernel: scsi: ses: Fix possible desc_ptr out-of-bounds accesses (CVE-2023-53675)
* kernel: Bluetooth: hci_event: Fix UAF in hci_acl_create_conn_sync (CVE-2025-39982)
* kernel: tls: wait for pending async decryptions if tls_strp_msg_hold fails (CVE-2025-40176)
* kernel: usb: dwc3: Fix race condition between concurrent dwc3_remove_requests() call paths (CVE-2025-68287)
* kernel: libceph: fix potential use-after-free in have_mon_and_osd_map() (CVE-2025-68285)

"text": "In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/rxe: Fix incomplete state save in rxe_requester\n\nIf a send packet is dropped by the IP layer in rxe_requester()\nthe call to rxe_xmit_packet() can fail with err == -EAGAIN.\nTo recover, the state of the wqe is restored to the state before\nthe packet was sent so it can be resent. However, the routines\nthat save and restore the state miss a significnt part of the\nvariable state in the wqe, the dma struct which is used to process\nthrough the sge table. And, the state is not saved before the packet\nis built which modifies the dma struct.\n\nUnder heavy stress testing with many QPs on a fast node sending\nlarge messages to a slow node dropped packets are observed and\nthe resent packets are corrupted because the dma struct was not\nrestored. This patch fixes this behavior and allows the test cases\nto succeed.",

"text": "The vulnerability occurs when rxe_requester attempts to retransmit a packet after receiving -EAGAIN from the IP layer. The code saves work queue element state to enable retransmission, but fails to preserve the DMA structure that tracks scatter-gather list processing. Additionally, the state snapshot happens after packet construction has already modified the DMA fields. When heavy network stress causes packet drops\u2014particularly when a fast sender communicates with a slow receiver across multiple queue pairs\u2014the incomplete restoration causes retransmitted packets to carry corrupted payload data.",
