Title
net: qualcomm: rmnet: fix global oob in rmnet_policy
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: qualcomm: rmnet: fix global oob in rmnet_policy
The variable rmnet_link_ops assign a *bigger* maxtype which leads to a
global out-of-bounds read when parsing the netlink attributes. See bug
trace below:

According to the comment of `nla_parse_nested_deprecated`, the maxtype
should be len(destination array) - 1. Hence use `IFLA_RMNET_MAX` here.

"value": "AV:L - The vulnerability is reached by a local `sendmsg()` on an `AF_NETLINK`/`NETLINK_ROUTE` socket carrying a crafted `RTM_NEWLINK` message, not by any remotely received packet. Per kernel guidance, netlink/rtnetlink-driven bugs are Local.\nAC:L - A single deterministic netlink message containing `IFLA_INFO_KIND=\"rmnet\"` plus an `IFLA_INFO_DATA` attribute of type 3 triggers the out-of-bounds access every time, with no race, no heap grooming, and no dependence on runtime state. The driver can even be autoloaded on demand via `MODULE_ALIAS_RTNL_LINK(\"rmnet\")`.\nPR:L - `rtnetlink_rcv_msg` only enforces `netlink_net_capable(skb, CAP_NET_ADMIN)`, evaluated against the network namespace\u0027s owning user namespace, so any unprivileged user gains it with `unshare -Urn`. No real root and no init-namespace privilege is required.\nUI:N - The attacker triggers the whole sequence from its own process by sending one netlink message; no victim action, mount, or configuration step is involved.\nS:U - The out-of-bounds read, the resulting crash, and any leaked data all stay within the kernel\u0027s own security authority. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - The OOB `struct nla_policy` contents are not merely read internally \u2014 the `out_err` path stores the out-of-bounds entry in `extack-\u003epolicy`, and `netlink_ack()` serializes its fields into `NLMSGERR_ATTR_POLICY` back to the attacker, disclosing kernel `.rodata` beyond the object. If the garbage decodes as `NLA_REJECT`, `extack-\u003e_msg` becomes an unvalidated pointer that is `strlen()`ed and copied to userspace, escalating this to an arbitrary-address kernel memory read.\nI:H - Adjacent read-only data is type-confused into a policy descriptor whose function pointer is invoked directly (`pt-\u003evalidate(nla, extack)` under `NLA_VALIDATE_FUNCTION`) and whose `nested_policy` pointer is dereferenced for recursive validation, yielding a control-flow hijack primitive. Per guidance, type confusion of a structure containing called function pointers is scored High.\nA:H - `BUG_ON(pt-\u003etype \u003e NLA_TYPE_MAX)` in `validate_nla()` fires for the large majority of possible adjacent byte values, producing an oops/panic; the wild `nested_policy` dereference is an additional crash path. The oops occurs with `rtnl_lock` held, so even without `panic_on_oops` the mutex is orphaned and all subsequent network configuration deadlocks permanently."

"value": "AV:L - The vulnerability is reached by a local `sendmsg()` on an `AF_NETLINK`/`NETLINK_ROUTE` socket carrying a crafted `RTM_NEWLINK` message, not by any remotely received packet. Per kernel guidance, netlink/rtnetlink-driven bugs are Local.\nAC:L - A single deterministic netlink message containing `IFLA_INFO_KIND=\"rmnet\"` plus an `IFLA_INFO_DATA` attribute of type 3 triggers the out-of-bounds access every time, with no race, no heap grooming, and no dependence on runtime state. The driver can even be autoloaded on demand via `MODULE_ALIAS_RTNL_LINK(\"rmnet\")`.\nPR:L - `rtnetlink_rcv_msg` only enforces `netlink_net_capable(skb, CAP_NET_ADMIN)`, evaluated against the network namespace\u0027s owning user namespace, so any unprivileged user gains it with `unshare -Urn`. No real root and no init-namespace privilege is required.\nUI:N - The attacker triggers the whole sequence from its own process by sending one netlink message; no victim action, mount, or configuration step is involved.\nS:U - The out-of-bounds read, the resulting crash, and any leaked data all stay within the kernel\u0027s own security authority. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - The OOB `struct nla_policy` contents are not merely read internally \u2014 the `out_err` path stores the out-of-bounds entry in `extack-\u003epolicy`, and `netlink_ack()` serializes its fields into `NLMSGERR_ATTR_POLICY` back to the attacker, disclosing kernel `.rodata` beyond the object. If the garbage decodes as `NLA_REJECT`, `extack-\u003e_msg` becomes an unvalidated pointer that is `strlen()`ed and copied to userspace, escalating this to an arbitrary-address kernel memory read.\nI:H - Adjacent read-only data is type-confused into a policy descriptor whose function pointer is invoked directly (`pt-\u003evalidate(nla, extack)` under `NLA_VALIDATE_FUNCTION`) and whose `nested_policy` pointer is dereferenced for recursive validation, yielding a control-flow hijack primitive. Per guidance, type confusion of a structure containing called function pointers is scored High.\nA:H - `BUG_ON(pt-\u003etype \u003e NLA_TYPE_MAX)` in `validate_nla()` fires for the large majority of possible adjacent byte values, producing an oops/panic; the wild `nested_policy` dereference is an additional crash path. The oops occurs with `rtnl_lock` held, so even without `panic_on_oops` the mutex is orphaned and all subsequent network configuration deadlocks permanently."
