In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Set tb->root_switch to NULL when domain is stopped Similarly what we do with the firmware connection manager. This makes tb_xdp_handle_request() return error to the remote host. However, we need to make sure we keep the uuid alive so that we can reply until the whole domain is released.

  - In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: Fix buffer overflow in     debugfs If the user tries to write more than 32 bytes then it results in memory corruption. Fortunately,     this is debugfs so it's limited to root users. (CVE-2025-38317)

  - In the Linux kernel, the following vulnerability has been resolved: drm/xe/pf: Clear all LMTT pages on     alloc Our LMEM buffer objects are not cleared by default on alloc and during VF provisioning we only setup     LMTT PTEs for the actually provisioned LMEM range. But beyond that valid range we might leave some stale     data that could either point to some other VFs allocations or even to the PF pages. Explicitly clear all     new LMTT page to avoid the risk that a malicious VF would try to exploit that gap. While around add     asserts to catch any undesired PTE overwrites and low-level debug traces to track LMTT PT life-cycle.

  - In the Linux kernel, the following vulnerability has been resolved: bpf: Fix metadata_dst leak
    __bpf_redirect_neigh_v{4,6} Cilium has a BPF egress gateway feature which forces outgoing K8s Pod traffic     to pass through dedicated egress gateways which then SNAT the traffic in order to interact with stable IPs     outside the cluster. The traffic is directed to the gateway via vxlan tunnel in collect md mode. A recent     BPF change utilized the bpf_redirect_neigh() helper to forward packets after the arrival and decap on     vxlan, which turned out over time that the kmalloc-256 slab usage in kernel was ever-increasing. The issue     was that vxlan allocates the metadata_dst object and attaches it through a fake dst entry to the skb. The     latter was never released though given bpf_redirect_neigh() was merely setting the new dst entry via     skb_dst_set() without dropping an existing one first. (CVE-2025-40183)

  - In the Linux kernel, the following vulnerability has been resolved: mlxsw: spectrum_router: Fix neighbour     use-after-free We sometimes observe use-after-free when dereferencing a neighbour [1]. The problem seems     to be that the driver stores a pointer to the neighbour, but without holding a reference on it. A     reference is only taken when the neighbour is used by a nexthop. Fix by simplifying the reference counting     scheme. Always take a reference when storing a neighbour pointer in a neighbour entry. Avoid taking a     referencing when the neighbour is used by a nexthop as the neighbour entry associated with the nexthop     already holds a reference. Tested by running the test that uncovered the problem over 300 times. Without     this patch the problem was reproduced after a handful of iterations.

The AlmaLinux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1793370479 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: Fix buffer overflow in     debugfs If the user tries to write more than 32 bytes then it results in memory corruption. Fortunately,     this is debugfs so it's limited to root users. (CVE-2025-38317)

  - In the Linux kernel, the following vulnerability has been resolved: drm/xe/pf: Clear all LMTT pages on     alloc Our LMEM buffer objects are not cleared by default on alloc and during VF provisioning we only setup     LMTT PTEs for the actually provisioned LMEM range. But beyond that valid range we might leave some stale     data that could either point to some other VFs allocations or even to the PF pages. Explicitly clear all     new LMTT page to avoid the risk that a malicious VF would try to exploit that gap. While around add     asserts to catch any undesired PTE overwrites and low-level debug traces to track LMTT PT life-cycle.

  - In the Linux kernel, the following vulnerability has been resolved: bpf: Fix metadata_dst leak
    __bpf_redirect_neigh_v{4,6} Cilium has a BPF egress gateway feature which forces outgoing K8s Pod traffic     to pass through dedicated egress gateways which then SNAT the traffic in order to interact with stable IPs     outside the cluster. The traffic is directed to the gateway via vxlan tunnel in collect md mode. A recent     BPF change utilized the bpf_redirect_neigh() helper to forward packets after the arrival and decap on     vxlan, which turned out over time that the kmalloc-256 slab usage in kernel was ever-increasing. The issue     was that vxlan allocates the metadata_dst object and attaches it through a fake dst entry to the skb. The     latter was never released though given bpf_redirect_neigh() was merely setting the new dst entry via     skb_dst_set() without dropping an existing one first. (CVE-2025-40183)

  - In the Linux kernel, the following vulnerability has been resolved: mlxsw: spectrum_router: Fix neighbour     use-after-free We sometimes observe use-after-free when dereferencing a neighbour [1]. The problem seems     to be that the driver stores a pointer to the neighbour, but without holding a reference on it. A     reference is only taken when the neighbour is used by a nexthop. Fix by simplifying the reference counting     scheme. Always take a reference when storing a neighbour pointer in a neighbour entry. Avoid taking a     referencing when the neighbour is used by a nexthop as the neighbour entry associated with the nexthop     already holds a reference. Tested by running the test that uncovered the problem over 300 times. Without     this patch the problem was reproduced after a handful of iterations.

  - In the Linux kernel, the following vulnerability has been resolved: net/sched: act_mirred: use the backlog     for mirred ingress The test Davide added in commit ca22da2fbd69 (act_mirred: use the backlog for nested     calls to mirred ingress) hangs our testing VMs every 10 or so runs, with the familiar tcp_v4_rcv ->     tcp_v4_rcv deadlock reported by lockdep. The problem as previously described by Davide (see Link) is that     if we reverse flow of traffic with the redirect (egress -> ingress) we may reach the same socket which     generated the packet. And we may still be holding its socket lock. The common solution to such deadlocks     is to put the packet in the Rx backlog, rather than run the Rx path inline. Do that for all egress ->     ingress reversals, not just once we started to nest mirred calls. In the past there was a concern that the     backlog indirection will lead to loss of error reporting / less accurate stats. But the current workaround     does not seem to address the issue.

  - In the Linux kernel, the following vulnerability has been resolved: vfs: Don't evict inode under the inode     lru traversing context The inode reclaiming process(See function prune_icache_sb) collects all reclaimable     inodes and mark them with I_FREEING flag at first, at that time, other processes will be stuck if they try     getting these inodes (See function find_inode_fast), then the reclaiming process destroy the inodes by     function dispose_list(). Some filesystems(eg. ext4 with ea_inode feature, ubifs with xattr) may do inode     lookup in the inode evicting callback function, if the inode lookup is operated under the inode lru     traversing context, deadlock problems may happen. Case 1: In function ext4_evict_inode(), the ea inode     lookup could happen if ea_inode feature is enabled, the lookup process will be stuck under the evicting     context like this: 1. File A has inode i_reg and an ea inode i_ea 2. getfattr(A, xattr_buf) // i_ea is     added into lru // lru->i_ea 3. Then, following three processes running like this: PA PB echo 2 >     /proc/sys/vm/drop_caches shrink_slab prune_dcache_sb // i_reg is added into lru, lru->i_ea->i_reg     prune_icache_sb list_lru_walk_one inode_lru_isolate i_ea->i_state |= I_FREEING // set inode state     inode_lru_isolate __iget(i_reg) spin_unlock(&i_reg->i_lock) spin_unlock(lru_lock) rm file A i_reg->nlink =     0 iput(i_reg) // i_reg->nlink is 0, do evict ext4_evict_inode ext4_xattr_delete_inode     ext4_xattr_inode_dec_ref_all ext4_xattr_inode_iget ext4_iget(i_ea->i_ino) iget_locked find_inode_fast
    __wait_on_freeing_inode(i_ea) ---- AA deadlock dispose_list // cannot be executed by prune_icache_sb     wake_up_bit(&i_ea->i_state) Case 2: In deleted inode writing function ubifs_jnl_write_inode(), file     deleting process holds BASEHD's wbuf->io_mutex while getting the xattr inode, which could race with inode     reclaiming process(The reclaiming process could try locking BASEHD's wbuf->io_mutex in inode evicting     function), then an ABBA deadlock problem would happen as following: 1. File A has inode ia and a     xattr(with inode ixa), regular file B has inode ib and a xattr. 2. getfattr(A, xattr_buf) // ixa is added     into lru // lru->ixa 3. Then, following three processes running like this: PA PB PC echo 2 >     /proc/sys/vm/drop_caches shrink_slab prune_dcache_sb // ib and ia are added into lru, lru->ixa->ib->ia     prune_icache_sb list_lru_walk_one inode_lru_isolate ixa->i_state |= I_FREEING // set inode state     inode_lru_isolate __iget(ib) spin_unlock(&ib->i_lock) spin_unlock(lru_lock) rm file B ib->nlink = 0 rm     file A iput(ia) ubifs_evict_inode(ia) ubifs_jnl_delete_inode(ia) ubifs_jnl_write_inode(ia)     make_reservation(BASEHD) // Lock wbuf->io_mutex ubifs_iget(ixa->i_ino) iget_locked find_inode_fast
    __wait_on_freeing_inode(ixa) | iput(ib) // ib->nlink is 0, do evict | ubifs_evict_inode |     ubifs_jnl_delete_inode(ib)  ubifs_jnl_write_inode ABBA deadlock -----make_reservation(BASEHD)     dispose_list // cannot be executed by prune_icache_sb wake_up_bit(&ixa->i_state) Fix the possible deadlock     by using new inode state flag I_LRU_ISOLATING to pin the inode in memory while inode_lru_isolate(

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.

  - thunderbolt: Set tb->root_switch to NULL when domain is stopped Similarly what we do with the firmware     connection manager. This makes tb_xdp_handle_request() return error to the remote host. However, we need     to make sure we keep the uuid alive so that we can reply until the whole domain is released.
    (CVE-2026-97508)

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