Moderate: kernel-rt security, bug fix, and enhancement update

Published Oct 1, 2026 · Updated Oct 1, 2026

Summary

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: RDMA/siw: Reject MPA FPDU length underflow before signed receive math (CVE-2026-64102)

* kernel: vmxnet3: fix BUG_ON in vmxnet3_get_hdr_len() for Geneve packets (CVE-2026-68299)

* kernel: net/liquidio: drop cached VF pci_dev LUT (CVE-2026-72329)

* kernel: dm-integrity: don't increment hash_offset twice (CVE-2026-72099)

Bug Fix(es) and Enhancement(s):

* [Rocky Linux 8.10] "kernel BUG at lib/list_debug.c:28!": list_add corruption in register_trace_event Rocky Linux 8.10 (JIRA:Rocky Linux-214136)

* request_key_auth use-after-free on every request-key upcall since 4.18.0-553.165.1 (regression from CVE-2026-63823 backport) (JIRA:Rocky Linux-270349)

  • Critical 9.8

    RDMA/siw: Reject MPA FPDU length underflow before signed receive math

    In the Linux kernel, the following vulnerability has been resolved: RDMA/siw: Reject MPA FPDU length underflow before signed receive math A malicious connected siw peer can send an iWARP FPDU whose MPA length field (c_hdr->mpa_len, 16 bit big-endian, peer-con…

    net/liquidio: drop cached VF pci_dev LUT

    In the Linux kernel, the following vulnerability has been resolved: net/liquidio: drop cached VF pci_dev LUT The PF SR-IOV enable path caches VF pci_dev pointers in dpiring_to_vfpcidev_lut[] by iterating with pci_get_device(). Those entries do not own a refer…

    vmxnet3: fix BUG_ON in vmxnet3_get_hdr_len() for Geneve packets

    In the Linux kernel, the following vulnerability has been resolved: vmxnet3: fix BUG_ON in vmxnet3_get_hdr_len() for Geneve packets vmxnet3_get_hdr_len() assumes gdesc->rcd.v4/v6/tcp always describe the outer header, but for a Geneve-encapsulated packet the d…

  • High 7.1

    dm-integrity: don't increment hash_offset twice

    In the Linux kernel, the following vulnerability has been resolved: dm-integrity: don't increment hash_offset twice hash_offset is already incremented in the loop "for (i = 0; i < to_copy; i++, ts--)". Do not increment it again.
