In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix the ACK parser to extract the SACK table for parsing Fix modification of the received skbuff in rxrpc_input_soft_acks() and a potential incorrect access of the buffer in a fragmented UDP packet (the packet would probably have to be deliberately pre-generated as fragmented) when AF_RXRPC tries to extract the contents of the SACK table by copying out the contents of the SACK table into a buffer before attempting to parse AF_RXRPC assumes that it can just call skb_condense() and then validly access the SACK table from skb->data and that it will be a flat buffer - but skb_condense() can silently fail to do anything under some circumstances. Note that whilst rxrpc_input_soft_acks() should be able to parse extended ACKs, the rest of AF_RXRPC doesn't currently support that. Further, there's then no need to call skb_condense() in rxrpc_input_ack(), so don't.

An update of the linux package has been released.

The Rocky Linux 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.

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For the stable distribution (trixie), these problems have been fixed in     version 6.12.95-1.

    We recommend that you upgrade your linux packages.

    For the detailed security status of linux please refer to its security     tracker page at:
    https://security-tracker.debian.org/tracker/linux

Tenable has extracted the preceding description block directly from the Debian security advisory.

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.

  - rxrpc: Fix the ACK parser to extract the SACK table for parsing Fix modification of the received skbuff in     rxrpc_input_soft_acks() and a potential incorrect access of the buffer in a fragmented UDP packet (the     packet would probably have to be deliberately pre-generated as fragmented) when AF_RXRPC tries to extract     the contents of the SACK table by copying out the contents of the SACK table into a buffer before     attempting to parse AF_RXRPC assumes that it can just call skb_condense() and then validly access the SACK     table from skb->data and that it will be a flat buffer - but skb_condense() can silently fail to do     anything under some circumstances. Note that whilst rxrpc_input_soft_acks() should be able to parse     extended ACKs, the rest of AF_RXRPC doesn't currently support that. Further, there's then no need to call     skb_condense() in rxrpc_input_ack(), so don't. (CVE-2026-53151)

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