Title
ipv6: mcast: Delay put pmc->idev in mld_del_delrec()
Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6: mcast: Delay put pmc->idev in mld_del_delrec()
pmc->idev is still used in ip6_mc_clear_src(), so as mld_clear_delrec()
does, the reference should be put after ip6_mc_clear_src() return.

{
"lang": "en",
"value": "AV:L - The vulnerable `mld_del_delrec()` path is entered from IPv6 multicast socket options (`IPV6_ADD_MEMBERSHIP`/`MCAST_JOIN_GROUP`) via `ipv6_sock_mc_join()` \u2192 `__ipv6_dev_mc_inc()`, which requires a local socket and local syscall access. The secondary `ipv6_mc_up()` call site is likewise local (RTNL/admin), so no remote packet processing reaches this code directly.\nAC:L - The attacker deterministically creates the required state himself \u2014 join a group, drop it (creating the `mc_tomb` entry through `mld_add_delrec()` in the default MLDv2 mode), then rejoin \u2014 with no race to win and no memory-layout precondition outside his control. All steps are ordinary `setsockopt()` calls that succeed on the first try.\nPR:L - Only an unprivileged local account is needed; `ipv6_sock_mc_join()`/`ipv6_sock_mc_drop()` perform no capability check, and joining a global-scope IPv6 multicast group is permitted to any user holding an `AF_INET6` socket. No `CAP_NET_ADMIN` or root is required, and the path is equally available inside an unprivileged user namespace with a veth/dummy device.\nUI:N - The entire sequence is driven by the attacker\u0027s own socket calls in a single process. No victim action, no filesystem mount, and no administrator involvement is needed.\nS:U - The premature reference drop and its consequences are confined to the kernel\u0027s own `inet6_dev` allocation and the network namespace that owns it. No hypervisor, IOMMU, or sandbox boundary is crossed, so the vulnerable component and impacted component share one security authority.\nC:H - Dropping the `inet6_dev` reference before `ip6_mc_clear_src()` finishes using `pmc-\u003eidev` is a use-after-free pattern on a refcounted network structure; once the object can be reclaimed, an attacker who sprays the freed `inet6_dev` slab gains a read primitive over attacker-shaped heap contents and adjacent kernel data. Per the UAF guidance this warrants High rather than a bounded pointer leak.\nI:H - A use-after-free on `inet6_dev` gives the attacker control over the contents subsequently dereferenced through `pmc-\u003eidev`, including the `mc_lock`/list pointers reached from `mc_dereference()`, which is the standard basis for heap-spray-driven arbitrary write and control-flow hijack. Type-confused reuse of the freed slab makes kernel memory modification achievable rather than merely theoretical.\nA:H - If the released reference is the last one, the following `ip6_mc_clear_src()` operates on freed memory, producing an oops or panic and taking the whole kernel down. The trigger is a repeatable unprivileged `setsockopt()` loop, so the crash can be induced at will."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
