Synopsis

The remote Red Hat host is missing one or more security updates for kernel-rt.

Description

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:1019 advisory.

* kernel: inactive elements in nft_pipapo_walk (CVE-2023-6817)

* kernel: netfilter: use-after-free in nft_trans_gc_catchall_sync leads to privilege escalation (CVE-2024-0193)

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

* kernel: Use-after-free in nft_verdict_dump due to a race between set GC and transaction (CVE-2023-4244)

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

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

* kernel: use-after-free during a race condition between a nonblocking atomic commit and a driver unload in drivers/gpu/drm/drm_atomic.c (CVE-2023-51043)

* kernel: nf_tables: use-after-free vulnerability in the nft_setelem_catchall_deactivate() function (CVE-2024-1085)

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