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.

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.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"14452ca3b5ce304fb2fea96dbc9ca1e4e7978551\", \"lessThan\": \"093dab655808207f7a9f54cf156240aeafc70590\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"14452ca3b5ce304fb2fea96dbc9ca1e4e7978551\", \"lessThan\": \"02467ab8b404d80429107588e0f3425cf5fcd2e5\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"14452ca3b5ce304fb2fea96dbc9ca1e4e7978551\", \"lessThan\": \"2295c22348faf795e1ccdf618f6eb7afdb2f7447\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"14452ca3b5ce304fb2fea96dbc9ca1e4e7978551\", \"lessThan\": \"3b5254862258b595662a0ccca6e9eeb88d6e7468\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"14452ca3b5ce304fb2fea96dbc9ca1e4e7978551\", \"lessThan\": \"ee1dc3bf86f2df777038506b139371a9add02534\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"14452ca3b5ce304fb2fea96dbc9ca1e4e7978551\", \"lessThan\": \"c4734535034672f59f2652e1e0058c490da62a5c\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"14452ca3b5ce304fb2fea96dbc9ca1e4e7978551\", \"lessThan\": \"17d06a5c44d8fd2e8e61bac295b09153496f87e1\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"14452ca3b5ce304fb2fea96dbc9ca1e4e7978551\", \"lessThan\": \"b33fb5b801c6db408b774a68e7c8722796b59ecc\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/net/ethernet/qualcomm/rmnet/rmnet_config.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"4.17\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"4.17\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"4.19.306\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"4.19.*\"}, {\"status\": \"unaffected\", \"version\": \"5.4.268\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.4.*\"}, {\"status\": \"unaffected\", \"version\": \"5.10.209\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.10.*\"}, {\"status\": \"unaffected\", \"version\": \"5.15.148\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.15.*\"}, {\"status\": \"unaffected\", \"version\": \"6.1.75\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.14\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.7.2\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.7.*\"}, {\"status\": \"unaffected\", \"version\": \"6.8\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/net/ethernet/qualcomm/rmnet/rmnet_config.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/093dab655808207f7a9f54cf156240aeafc70590\"}, {\"url\": \"https://git.kernel.org/stable/c/02467ab8b404d80429107588e0f3425cf5fcd2e5\"}, {\"url\": \"https://git.kernel.org/stable/c/2295c22348faf795e1ccdf618f6eb7afdb2f7447\"}, {\"url\": \"https://git.kernel.org/stable/c/3b5254862258b595662a0ccca6e9eeb88d6e7468\"}, {\"url\": \"https://git.kernel.org/stable/c/ee1dc3bf86f2df777038506b139371a9add02534\"}, {\"url\": \"https://git.kernel.org/stable/c/c4734535034672f59f2652e1e0058c490da62a5c\"}, {\"url\": \"https://git.kernel.org/stable/c/17d06a5c44d8fd2e8e61bac295b09153496f87e1\"}, {\"url\": \"https://git.kernel.org/stable/c/b33fb5b801c6db408b774a68e7c8722796b59ecc\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nnet: qualcomm: rmnet: fix global oob in rmnet_policy\\n\\nThe variable rmnet_link_ops assign a *bigger* maxtype which leads to a\\nglobal out-of-bounds read when parsing the netlink attributes.
