The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1793786843 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: soc: qcom: qmi_encdec: Restrict string     length in decode The QMI TLV value for strings in a lot of qmi element info structures account for null     terminated strings with MAX_LEN + 1. If a string is actually MAX_LEN + 1 length, this will cause an out of     bounds access when the NULL character is appended in decoding. (CVE-2023-53729)

  - In the Linux kernel, the following vulnerability has been resolved: rv: Use strings in da monitors     tracepoints Using DA monitors tracepoints with KASAN enabled triggers the following warning: BUG: KASAN:
    global-out-of-bounds in do_trace_event_raw_event_event_da_monitor+0xd6/0x1a0 Read of size 32 at addr     ffffffffaada8980 by task ... Call Trace: <TASK> [...] do_trace_event_raw_event_event_da_monitor+0xd6/0x1a0     ? __pfx_do_trace_event_raw_event_event_da_monitor+0x10/0x10 ? trace_event_sncid+0x83/0x200     trace_event_sncid+0x163/0x200 [...] The buggy address belongs to the variable: automaton_snep+0x4e0/0x5e0     This is caused by the tracepoints reading 32 bytes __array instead of __string from the automata     definition. Such strings are literals and reading 32 bytes ends up in out of bound memory accesses (e.g.
    the next automaton's data in this case). The error is harmless as, while printing the string, we stop at     the null terminator, but it should still be fixed. Use the __string facilities while defining the     tracepoints to avoid reading out of bound memory. (CVE-2025-38636)

  - In the Linux kernel, the following vulnerability has been resolved: perf: arm_spe: Prevent overflow in     PERF_IDX2OFF() Cast nr_pages to unsigned long to avoid overflow when handling large AUX buffer sizes (>= 2     GiB). (CVE-2025-40081)

  - In the Linux kernel, the following vulnerability has been resolved: arch_topology: Fix incorrect error     check in topology_parse_cpu_capacity() Fix incorrect use of PTR_ERR_OR_ZERO() in     topology_parse_cpu_capacity() which causes the code to proceed with NULL clock pointers. The current logic     uses !PTR_ERR_OR_ZERO(cpu_clk) which evaluates to true for both valid pointers and NULL, leading to     potential NULL pointer dereference in clk_get_rate(). Per include/linux/err.h documentation,     PTR_ERR_OR_ZERO(ptr) returns: The error code within @ptr if it is an error pointer; 0 otherwise. This     means PTR_ERR_OR_ZERO() returns 0 for both valid pointers AND NULL pointers. Therefore     !PTR_ERR_OR_ZERO(cpu_clk) evaluates to true (proceed) when cpu_clk is either valid or NULL, causing     clk_get_rate(NULL) to be called when of_clk_get() returns NULL. Replace with !IS_ERR_OR_NULL(cpu_clk)     which only proceeds for valid pointers, preventing potential NULL pointer dereference in clk_get_rate().
    (CVE-2025-40346)

  - In the Linux kernel, the following vulnerability has been resolved: platform/x86/amd/pmc: Add support for     Van Gogh SoC The ROG Xbox Ally (non-X) SoC features a similar architecture to the Steam Deck. While the     Steam Deck supports S3 (s2idle causes a crash), this support was dropped by the Xbox Ally which only S0ix     suspend. Since the handler is missing here, this causes the device to not suspend and the AMD GPU driver     to crash while trying to resume afterwards due to a power hang. (CVE-2025-68334)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - bnxt_en: fix DMA mapping length for padded small packets Stefan Fleischmann reported Intel IOMMU DMA Read     faults on BCM57412 NetXtreme-E NICs when transmitting packets on VLAN/macvlan interfaces: DMAR: [DMA Read     NO_PASID] Request device [18:00.0] fault addr 0xfc499000 [fault reason 0x06] PTE Read access is not set     bnxt_en 0000:18:00.0 eno1np0: Abandoning msg {0xb4 0x41a} len: 0 due to firmware status: 0x2000001 ...
    NETDEV WATCHDOG: eno1np0 (bnxt_en): transmit queue 0 timed out The fault address (0xfc499000) is on an     exact 4KB page boundary, pointing to a DMA read buffer overrun. In bnxt_start_xmit(), packets smaller than     BNXT_MIN_PKT_SIZE (52 bytes), such as 42-byte untagged ARP frames, are padded: if (length <     BNXT_MIN_PKT_SIZE) { pad = BNXT_MIN_PKT_SIZE - length; if (skb_pad(skb, pad)) goto tx_kick_pending; length     = BNXT_MIN_PKT_SIZE; } mapping = dma_map_single(&pdev->dev, skb->data, len, DMA_TO_DEVICE); ...
    dma_unmap_len_set(tx_buf, len, len); However, 'len' was initialized earlier to skb_headlen(skb) (e.g. 42     bytes) and is left unadjusted after padding. Consequently, dma_map_single() and dma_unmap_len_set() map     and track only 42 bytes. Later, the hardware TX buffer descriptor is programmed with the padded length:
    txbd->tx_bd_len_flags_type = cpu_to_le32(((len + pad) << TX_BD_LEN_SHIFT) | flags |     TX_BD_FLAGS_PACKET_END); The NIC DMA engine is thus instructed to read 52 bytes from a region where only     42 bytes were DMA-mapped. If skb->data ends near the boundary of a 4KB page (within 'pad' bytes of the     next page), the hardware DMA read overruns into the unmapped adjacent page, triggering an IOMMU fault.
    This issue was exposed after commit 447cbe95ebb9 (vlan: fix skb_under_panic and races when toggling HW     VLAN offload) because reserving extra VLAN headroom rounded LL_RESERVED_SPACE from 48 up to 64 bytes,     shifting skb->data offsets and potentially causing small frames to land right against page boundaries. Fix     this by using skb_put_padto(skb, BNXT_MIN_PKT_SIZE) in bnxt_start_xmit(), before skb_shinfo(skb)->nr_frags     is sampled, because padding might linearize the skb. This ensures skb->len and skb_headlen(skb) reflect     the padded size so that dma_map_single() maps the full buffer and the descriptor length is consistent.
    This also removes the temporary 'pad' variable and masking logic. The padding is done after the SW USO     branch, otherwise bnxt_sw_udp_gso_xmit() would account the padding as UDP payload and send it in extra     segments. Note that SW USO segments are still not padded: with IPv4, a segment carrying less than 10 bytes     of UDP payload (small gso_size, or a short last segment) is sent as a frame shorter than     BNXT_MIN_PKT_SIZE. This is a separate issue, left for a followup patch. (CVE-2026-99081)

Note that Nessus relies on the presence of the package as reported by the vendor.
