[RHSA-2024:1614] kernel-rt security and bug fix update

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)
