CVE-2024-52332 affects the Linux kernel's Intel igb Ethernet driver. When pci_register_driver() fails during igb_init_module(), the driver could leave dca_notifier registered; a subsequent notifier call could then access invalid memory after the driver installation has failed. The defect, present since kernel version 2.6.29, can cause a local denial of service. Upstream fixes are available in stable kernels 5.4.287, 5.10.231, 5.15.174, 6.1.120, 6.6.66, 6.12.5, and 6.13-rc2.
Red Hat rated the flaw Moderate with CVSS 4.7, citing required local access, low privileges, high attack complexity, and high availability impact. Fixes were issued for standard kernels in RHEL 9 and RHEL 10 through RHSA-2025:20518 and RHSA-2025:20095; RHEL 10 kernel-rt remains affected, while RHEL 9 kernel-rt is marked will not fix. Organizations should update to a current vendor-supported kernel release rather than backporting the isolated patch; where patching is not immediately feasible, Red Hat recommends preventing the igb module from loading, including by blacklisting it when operationally viable.

Red Hat released RHSA-2025:20518 for the RHEL 9 standard kernel and RHSA-2025:20095 for the RHEL 10 standard kernel to address CVE-2024-52332. RHEL 10 kernel-rt remained affected without an identified erratum, while RHEL 9 kernel-rt was marked will not fix.
The Linux kernel CVE team published an advisory for CVE-2024-52332, documenting the Intel igb driver flaw and fixes in stable kernel versions 5.4.287, 5.10.231, 5.15.174, 6.1.120, 6.6.66, 6.12.5, and 6.13-rc2.
A change in Linux kernel version 2.6.29 introduced an error-path flaw in the Intel igb driver's igb_init_module() function: dca_notifier was not unregistered if pci_register_driver() failed, potentially enabling invalid memory access on a later notifier call.

**CVE-2023-45871** is an Important-rated buffer overflow in the Linux kernel’s Intel IGB Ethernet driver. When `rx-all`/store-bad-packet behavior is enabled, an oversized physical-layer frame can overflow a receive-ring buffer in `igb_configure_rx_ring`, potentially compromising system confidentiality, integrity, and availability. Red Hat assigned the flaw a CVSS v3.1 score of 7.5; exploitation requires an adjacent-network attacker and is considered high complexity because it depends on oversized frames and a non-default configuration. The upstream kernel fix updates `igb_set_rx_buffer_len` to allocate large receive buffers on systems with page sizes below 8192 bytes when either frames exceed `IGB_MAX_FRAME_BUILD_SKB` or the `E1000_RCTL_SBP` receive-control flag is set. Red Hat released corrected kernel, `kernel-rt`, and `kpatch` packages for affected Red Hat Enterprise Linux 7 and 8 streams in February and March 2024, with no qualifying mitigation listed at the time of its advisory.

**CVE-2025-39973** affects the Linux kernel’s Intel i40e Ethernet driver: a malicious virtual function can provide an oversized or misaligned `ring_len` value that is passed to a hardware memory context without adequate validation. The condition can create excessive transmit or receive queue lengths, potentially resulting in memory corruption or undefined behavior. Red Hat rates the issue Moderate with a CVSS v3.1 score of 7.5, while CVE.org assigns 8.8 under different environmental assumptions; RHEL 7 through 10, including applicable real-time kernels, are listed as affected, while RHEL 6 is not affected. The defect aligns with **CWE-131**, incorrect calculation of buffer size, a memory-safety weakness that can lead to out-of-bounds access, crashes, sensitive-data exposure, or code execution. Red Hat’s RHSA-2025:21469 provides updated RHEL 9 kernel packages for multiple kernel security issues and requires a reboot after installation; however, Red Hat’s CVE record separately reports no qualifying mitigation for CVE-2025-39973. Organizations should identify systems using affected i40e hardware and virtual-function configurations, apply applicable vendor kernel updates, reboot hosts, and restrict untrusted VF access where operationally possible.

**CVE-2024-26939** is a use-after-free flaw in the Linux kernel's Intel i915 DRM graphics driver, in `drivers/gpu/drm/i915/i915_vma.c`. A race between i915 VMA destruction and asynchronous retirement can free a VMA while retirement logic still accesses it, allowing a local low-privileged attacker to crash the affected system. The vulnerability was introduced in Linux 5.19 and can produce debug-object warnings when a GPU GT is parked. The issue is fixed upstream in Linux kernel versions 6.1.88, 6.6.29, 6.8.3, and 6.9-rc2 and later stable releases. Red Hat has issued fixes for RHEL 8, RHEL 8 kernel-rt, RHEL 9, and RHEL 9.4 Extended Update Support; RHEL 9 kernel-rt is marked will not fix, while RHEL 6 and 7 variants are outside support scope. Red Hat rates the flaw Moderate at CVSS 5.5, compared with scores of 7.0 from NVD and 7.8 from CVE.org.
