high Nessus Plugin ID 206556

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-2024:6268 advisory.

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.

* kernel: kprobes/x86: Use copy_from_kernel_nofault() to read from unsafe address (CVE-2024-26946)

* kernel: netfilter: bridge: replace physindev with physinif in nf_bridge_info (CVE-2024-35839)

* kernel: bpf, sockmap: Prevent lock inversion deadlock in map delete elem (CVE-2024-35895)

* kernel: x86/coco: Require seeding RNG with RDRAND on CoCo systems (CVE-2024-35875)

* kernel: gfs2: Fix potential glock use-after-free on unmount (CVE-2024-38570)

* kernel: bnxt_re: avoid shift undefined behavior in bnxt_qplib_alloc_init_hwq (CVE-2024-38540)

* kernel: ionic: fix use after netif_napi_del() (CVE-2024-39502)

* kernel: mm/huge_memory: don't unpoison huge_zero_folio (CVE-2024-40914)

* kernel: dmaengine: idxd: Fix possible Use-After-Free in irq_process_work_list (CVE-2024-40956)

* kernel: scsi: qedi: Fix crash while reading debugfs attribute (CVE-2024-40978)

* kernel: tipc: force a dst refcount before doing decryption (CVE-2024-40983)

* kernel: ppp: reject claimed-as-LCP but actually malformed packets (CVE-2024-41044)

* kernel: Revert mm/writeback: fix possible divide-by-zero in wb_dirty_limits(), again (CVE-2024-42102)

* kernel: mm: avoid overflows in dirty throttling logic (CVE-2024-42131)
