    Title
    Dpdk: dpdk: guest-triggered use-after-free and type confusion in vhost-crypto session cleanup
    Summary
    A flaw was found in DPDK lib/vhost vhost-crypto. Session cleanup can leave a stale cached session pointer, and the data path does not check the session type before attaching it, leading to use-after-free or type confusion in the host vhost-crypto backend.

    CVE-2026-100236 (GCVE-0-2026-100236)

    Vulnerability from nvd – Published: 2026-10-14 16:33 – Updated: 2026-10-20 01:41
    VLAI
    Title
    Dpdk: dpdk: heap out-of-bounds read/write in gso header copy
    Summary
    A flaw was found in the DPDK GSO library. When software GSO copies packet headers into a new mbuf, it does not check that the header fits in the source first segment or in the destination buffer, and a header longer than the configured GSO segment size can underflow the payload-size calculation. A remote or guest-supplied packet processed with software GSO can trigger an out-of-bounds read or write.

    CVE-2026-93683 (GCVE-0-2026-93683)

    Vulnerability from nvd – Published: 2026-10-14 15:42 – Updated: 2026-10-14 17:43
    VLAI
    Title
    Dpdk: dpdk: guest-triggered out-of-bounds walk via vhost indirect descriptor length toctou
    Summary
    A flaw was found in the DPDK vhost library. When handling a virtio indirect descriptor table, the host reads the table length more than once from guest memory and can allocate a host copy before validating that length. A guest that changes the length between those reads, or that supplies an out-of-range next index on a small host copy in the vDPA relay path, can cause the host vhost process to walk past the validated mapping or heap copy. That can crash or disrupt the vhost process. Out-of-bounds bytes are consumed as descriptor fields for GPA translation and are not returned to the guest as payload. This is a residual issue in the non-contiguous indirect descriptor copy path introduced as part of the CVE-2018-1059 fix.

A guest that changes the length between those reads, or that supplies an out-of-range next index on a small host copy in the vDPA relay path, can cause the host vhost process to walk past the validated mapping or heap copy. That can crash or disrupt the vhost process. Out-of-bounds bytes are consumed as descriptor fields for GPA translation and are not returned to the guest as payload. This is a residual issue in the non-contiguous indirect descriptor copy path introduced as part of the CVE-2018-1059 fix."

    Title
    Dpdk: dpdk: guest-triggered use-after-free and type confusion in vhost-crypto session cleanup
    Summary
    A flaw was found in DPDK lib/vhost vhost-crypto. Session cleanup can leave a stale cached session pointer, and the data path does not check the session type before attaching it, leading to use-after-free or type confusion in the host vhost-crypto backend.

    CVE-2026-100236 (GCVE-0-2026-100236)

    Vulnerability from cvelistv5 – Published: 2026-10-14 16:33 – Updated: 2026-10-20 01:41
    VLAI
    Title
    Dpdk: dpdk: heap out-of-bounds read/write in gso header copy
    Summary
    A flaw was found in the DPDK GSO library. When software GSO copies packet headers into a new mbuf, it does not check that the header fits in the source first segment or in the destination buffer, and a header longer than the configured GSO segment size can underflow the payload-size calculation. A remote or guest-supplied packet processed with software GSO can trigger an out-of-bounds read or write.

    CVE-2026-93683 (GCVE-0-2026-93683)

    Vulnerability from cvelistv5 – Published: 2026-10-14 15:42 – Updated: 2026-10-14 17:43

    Title
    Dpdk: dpdk: guest-triggered out-of-bounds walk via vhost indirect descriptor length toctou
    Summary
    A flaw was found in the DPDK vhost library. When handling a virtio indirect descriptor table, the host reads the table length more than once from guest memory and can allocate a host copy before validating that length. A guest that changes the length between those reads, or that supplies an out-of-range next index on a small host copy in the vDPA relay path, can cause the host vhost process to walk past the validated mapping or heap copy. That can crash or disrupt the vhost process. Out-of-bounds bytes are consumed as descriptor fields for GPA translation and are not returned to the guest as payload. This is a residual issue in the non-contiguous indirect descriptor copy path introduced as part of the CVE-2018-1059 fix.

A guest that changes the length between those reads, or that supplies an out-of-range next index on a small host copy in the vDPA relay path, can cause the host vhost process to walk past the validated mapping or heap copy. That can crash or disrupt the vhost process. Out-of-bounds bytes are consumed as descriptor fields for GPA translation and are not returned to the guest as payload. This is a residual issue in the non-contiguous indirect descriptor copy path introduced as part of the CVE-2018-1059 fix."
