The racing `dst_dev_put()` side likewise requires local netlink link/route teardown, so the entire attack is delivered through local syscalls.\nAC:L - The attacker controls both sides of the race \u2014 one thread repeatedly issues `setsockopt(TLS_TX)` on TCP sockets whose `sk_dst_cache` points at a veth while another deletes that veth in the attacker's own netns \u2014 and can retry indefinitely until the window between reading `dst->dev` and the `netdev_ref_replace()`/free is hit. `CONFIG_TLS_DEVICE` is a routinely enabled distro option, and the vulnerable read happens before any NIC-capability or `IFF_UP` gate, so no special hardware is required.\nPR:L - An ordinary unprivileged local account suffices: attaching the tls ULP and calling `setsockopt(SOL_TLS, ...)` requires no capability once the ULP is registered (the `capable(CAP_NET_ADMIN)` check in `__tcp_ulp_find_autoload()` gates only module autoload), and the CAP_NET_ADMIN needed to create and delete the veth is obtained in the attacker's own user+net namespace via `unshare -Urn`, not real root.\nUI:N - Exploitation is driven entirely by the attacker's own threads issuing socket syscalls and netlink link/route operations; no victim action, mount, or file open is involved.\nS:U - The use-after-free is on a kernel `struct net_device` and its consequences remain within the kernel's own security authority, with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - This is a use-after-free on a freed, heap-sprayable `net_device`: `netdev_sk_get_lower_dev()` reads `dev->netdev_ops` from freed memory and the caller subsequently reads `netdev->features` and `netdev->flags`, whose values are observable through the setsockopt return code and the resulting offload state, giving an attacker-groomable read of reclaimed kernel memory.\nI:H - The freed object is used for two indirect calls \u2014 `ops->ndo_sk_get_lower_dev(dev, sk)` and later `netdev->tlsdev_ops->tls_dev_add(...)` \u2014 both function pointers loaded out of reclaimed memory, and `dev_hold(lowest_dev)` performs a refcount increment inside the freed allocation, together yielding control-flow-hijack and write primitives once the slab is sprayed.\nA:H - Dereferencing and indirect-calling through a freed `net_device` reliably oopses the kernel even when not weaponized, and the race is repeatable at will by an unprivileged local user for a persistent denial of service."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":

This is a use-after-free on a freed, heap-sprayable `net_device`: `netdev_sk_get_lower_dev()` reads `dev->netdev_ops` from freed memory and the caller subsequently reads `netdev->features` and `netdev->flags`, whose values are observable through the setsockopt return code and the resulting offload state, giving an attacker-groomable read of reclaimed kernel memory.\nI:H - The freed object is used for two indirect calls \u2014 `ops->ndo_sk_get_lower_dev(dev, sk)` and later `netdev->tlsdev_ops->tls_dev_add(...)` \u2014 both function pointers loaded out of reclaimed memory, and `dev_hold(lowest_dev)` performs a refcount increment inside the freed allocation, together yielding control-flow-hijack and write primitives once the slab is sprayed.\nA:H - Dereferencing and indirect-calling through a freed `net_device` reliably oopses the kernel even when not weaponized, and the race is repeatable at will by an unprivileged local user for a persistent denial of service."}]}], "affected": [{"repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "vendor": "Linux", "product": "Linux", "versions": [{"status": "affected", "version": "e8f69799810c32dd40c6724d829eccc70baad07f", "lessThan": "2b1bef126bbb8d0da51491357559126d567c1dee", "versionType": "git"}, {"status": "affected", "version": "e8f69799810c32dd40c6724d829eccc70baad07f", "lessThan": "e37ca0092ddace60833790b4ad7a390408fb1be9", "versionType": "git"}, {"status": "affected", "version": "e8f69799810c32dd40c6724d829eccc70baad07f", "lessThan": "13159c7125636371543a82cb7bbae00ab36730cc", "versionType": "git"}, {"status": "affected", "version": "e8f69799810c32dd40c6724d829eccc70baad07f", "lessThan": "f09cd209359a23f88d4f3fa3d2379d057027e53c", "versionType": "git"}, {"status": "affected", "version": "e8f69799810c32dd40c6724d829eccc70baad07f", "lessThan": "feb474ddbf26b51f462ae2e60a12013bdcfc5407", "versionType": "git"}, {"status": "affected", "version": "e8f69799810c32dd40c6724d829eccc70baad07f", "lessThan": "c65f27b9c3be2269918e1cbad6d8884741f835c5", "versionType": "git"}], "programFiles": ["net/tls/tls_device.c"], "defaultStatus": "unaffected"}, {"repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "vendor": "Linux", "product": "Linux", "versions": [{"status": "affected", "version": "4.18"}, {"status": "unaffected", "version": "0", "lessThan": "4.18", "versionType": "semver"}, {"status": "unaffected", "version": "5.15.199", "versionType": "semver", "lessThanOrEqual": "5.15.*"}, {"status": "unaffected", "version": "6.1.161", "versionType": "semver", "lessThanOrEqual": "6.1.*"}, {"status": "unaffected", "version": "6.6.121", "versionType": "semver", "lessThanOrEqual": "6.6.*"}, {"status": "unaffected", "version": "6.12.66", "versionType": "semver", "lessThanOrEqual": "6.12.*"}, {"status": "unaffected", "version": "6.17.3", "versionType": "semver", "lessThanOrEqual": "6.17.*"}, {"status": "unaffected", "version": "6.18", "versionType": "original_commit_for_fix", "lessThanOrEqual": "*"}], "programFiles": ["net/tls/tls_device.c"], "defaultStatus": "affected"}], "references": [{"url": "https://git.kernel.org/stable/c/2b1bef126bbb8d0da51491357559126d567c1dee"}, {"url": "https://git.kernel.org/stable/c/e37ca0092ddace60833790b4ad7a390408fb1be9"}, {"url": "https://git.kernel.org/stable/c/13159c7125636371543a82cb7bbae00ab36730cc"}, {"url": "https://git.kernel.org/stable/c/f09cd209359a23f88d4f3fa3d2379d057027e53c"}, {"url": "https://git.kernel.org/stable/c/feb474ddbf26b51f462ae2e60a12013bdcfc5407"}, {"url": "https://git.kernel.org/stable/c/c65f27b9c3be2269918e1cbad6d8884741f835c5"}], "x_generator": {"engine": "bippy-1.2.0"}, "descriptions": [{"lang": "en", "value": "In the Linux kernel, the following vulnerability has been resolved:\n\ntls: Use __sk_dst_get() and dst_dev_rcu() in get_netdev_for_sock().\n\nget_netdev_for_sock() is called during setsockopt(),\nso not under RCU.\n\nUsing sk_dst_get(sk)->dev could trigger UAF.\n\nLet's use __sk_dst_get() and dst_dev_rcu().\n\nNote that the only ->ndo_sk_get_lower_dev() user is\nbond_sk_get_lower_dev(), which uses RCU."}], "cpeApplicability": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "versionEndExcluding": "5.15.199", "versionStartIncluding": "4.18"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "versionEndExcluding": "6.1.161", "versionStartIncluding": "4.18"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "versionEndExcluding": "6.6.121", "versionStartIncluding": "4.18"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "versionEndExcluding": "6.12.66", "versionStartIncluding": "4.18"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "versionEndExcluding": "6.17.3", "versionStartIncluding": "4.18"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "versionEndExcluding": "6.18", "versionStartIncluding": "4.18"}], "operator": "OR"}]}], "providerMetadata": {"orgId": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "shortName": "Linux", "dateUpdated": "2026-08-05T12:08:04.814Z"}}}, "cveMetadata": {"cveId": "CVE-2025-40149", "state": "PUBLISHED", "dateUpdated": "2026-11-10T12:37:41.180Z", "dateReserved": "2025-04-16T07:20:57.175Z", "assignerOrgId": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "datePublished": "2025-11-12T10:23:27.122Z", "assignerShortName": "Linux"}, "dataVersion": "5.2"}
