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

  - net: ethernet: ti: Fix return type of netcp_ndo_start_xmit() With clang's kernel control flow integrity     (kCFI, CONFIG_CFI_CLANG), indirect call targets are validated against the expected function pointer     prototype to make sure the call target is valid to help mitigate ROP attacks. If they are not identical,     there is a failure at run time, which manifests as either a kernel panic or thread getting killed. A     proposed warning in clang aims to catch these at compile time, which reveals:
    drivers/net/ethernet/ti/netcp_core.c:1944:21: error: incompatible function pointer types initializing     'netdev_tx_t (*)(struct sk_buff *, struct net_device *)' (aka 'enum netdev_tx (*)(struct sk_buff *, struct     net_device *)') with an expression of type 'int (struct sk_buff *, struct net_device *)'     [-Werror,-Wincompatible-function-pointer-types-strict] .ndo_start_xmit = netcp_ndo_start_xmit,     ^~~~~~~~~~~~~~~~~~~~ 1 error generated. ->ndo_start_xmit() in 'struct net_device_ops' expects a return     type of 'netdev_tx_t', not 'int'. Adjust the return type of netcp_ndo_start_xmit() to match the     prototype's to resolve the warning and CFI failure. (CVE-2022-50486)

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

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-011136 advisory.

    In the Linux kernel, the following vulnerability has been resolved:
