Summary
Important: kernel-rt security, bug fix, and enhancement update
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: crypto: af_alg - Disallow concurrent writes in af_alg_sendmsg (CVE-2025-39964)

  • kernel: Linux kernel Bluetooth: Denial of Service via race condition in hidp_session_thread (CVE-2023-54120)

  • kernel: Bluetooth: L2CAP: Fix potential user-after-free (CVE-2023-54214)

  • kernel: Bluetooth: btusb: revert use of devm_kzalloc in btusb (CVE-2025-71082)

  • kernel: Bluetooth: SMP: force responder MITM requirements before building the pairing response (CVE-2026-43334)

  • kernel: iommu/vt-d: Clear Present bit before tearing down PASID entry (CVE-2026-45894)

  • kernel: RDMA/rxe: Validate pad and ICRC before payload_size() in rxe_rcv (CVE-2026-46043)

  • kernel: RDMA/rxe: Reject unknown opcodes before ICRC processing (CVE-2026-46133)

  • kernel: Bluetooth: serialize accept_q access (CVE-2026-52918)

  • kernel: dm cache policy smq: fix missing locks in invalidating cache blocks (CVE-2026-53062)

  • kernel: iommu/amd: Fix clone_alias() to use the original device's devid (CVE-2026-53053)

  • kernel: Bluetooth: RFCOMM: hold listener socket in rfcomm_connect_ind() (CVE-2026-53256)

  • kernel: Bluetooth: RFCOMM: validate skb length in MCC handlers (CVE-2026-53254)

  • kernel: keys: Pin request_key_auth payload in instantiate paths (CVE-2026-63823)

  • kernel: Bluetooth: L2CAP: Fix possible crash on l2cap_ecred_conn_rsp (CVE-2026-63975)

  • kernel: Bluetooth: HIDP: fix missing length checks in hidp_input_report() (CVE-2026-63947)

  • kernel: nvmet-tcp: check INIT_FAILED before nvmet_req_uninit in digest error path (CVE-2026-64534)

  • kernel: RDMA/rxe: Fix a use-after-free problem in rxe_mmap (CVE-2026-64582)

  • kernel: net/mlx5: Fix MCIA register buffer overflow on 32 dword reads (CVE-2026-68293)

  • kernel: Linux kernel Bluetooth RFCOMM: Denial of Service via use-after-free in set_termios (CVE-2026-68188)

Bug Fix(es) and Enhancement(s):

  • Intel IOMMU: possible circular locking dependency (JIRA:Rocky Linux-243217)

  • xfs: repeated xfs_trans_cancel called from xfs_iomap_write_direct (JIRA:Rocky Linux-251578)
