Important: kernel-rt security and bug fix update

Published Apr 5, 2024 · Updated Feb 5, 2026

Ecosystem: Rocky Linux

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: vmwgfx: NULL pointer dereference in vmw_cmd_dx_define_query (CVE-2022-38096)

* kernel: Out of boundary write in perf_read_group() as result of overflow a perf_event's read_size (CVE-2023-6931)

* kernel: GSM multiplexing race condition leads to privilege escalation (CVE-2023-6546,ZDI-CAN-20527)

* kernel: CIFS Filesystem Decryption Improper Input Validation Remote Code Execution Vulnerability in function receive_encrypted_standard of client (CVE-2024-0565)

* kernel: use-after-free in amdgpu_cs_wait_all_fences in drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c (CVE-2023-51042)

* kernel: ext4: kernel bug in ext4_write_inline_data_end() (CVE-2021-33631)

* kernel: nf_tables: use-after-free vulnerability in the nft_verdict_init() function (CVE-2024-1086)

Bug Fix(es):

* kernel-rt: update RT source tree to the latest Rocky Linux-8.9.z3 Batch (JIRA:Rocky Linux-23853)

* kernel-rt: kernel: nf_tables: use-after-free vulnerability in the nft_verdict_init() function (JIRA:Rocky Linux-24015)
