CVE-2022-48816 (GCVE-0-2022-48816)
Vulnerability from cvelistv5
Published

Modified

Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: SUNRPC: lock against ->sock changing during sysfs read ->sock can be set to NULL asynchronously unless ->recv_mutex is held. So it is important to hold that mutex. Otherwise a sysfs read can trigger an oops. Commit 17f09d3f619a ("SUNRPC: Check if the xprt is connected before handling sysfs reads") appears to attempt to fix this problem, but it only narrows the race window.

no separate victim action such as opening a crafted file or mounting a filesystem is required at exploit time.\\nS:U - Impact is confined to the local host kernel (oops or socket UAF within SUNRPC/socket heap state) and does not cross a VM, IOMMU, or other security-authority boundary.\\nC:H - Without recv_mutex, a non-NULL sock pointer can be loaded then used after xs_reset_transport()\u0027s fput frees the socket, a classic socket UAF that heap spraying can turn into arbitrary kernel memory disclosure.\\nI:H - The same unlocked race allows use-after-free of the struct socket while kernel_getsockname/xs_sock_getport runs, enabling reclaim and corruption of adjacent heap state for arbitrary write and control-flow hijacking under standard UAF exploitation.\\nA:H - The documented failure mode is a kernel oops from NULL sock dereference during sysfs read, and the UAF path likewise crashes on stale socket use, so availability impact is High even without a full exploit.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"a8482488a7d6d320f63a9ee1912dbb5ae5b80a61\", \"lessThan\": \"fdc42287ae3f8a35cc2098307f52d7864b4bc8ed\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"a8482488a7d6d320f63a9ee1912dbb5ae5b80a61\", \"lessThan\": \"9482ab4540f5bcc869b44c067ae99b5fca16bd07\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"a8482488a7d6d320f63a9ee1912dbb5ae5b80a61\", \"lessThan\": \"b49ea673e119f59c71645e2f65b3ccad857c90ee\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"21a2be1a5145d072deedc7cdc5b2d17380abea75\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"77876473912d1bf1ed16bffa1674e5ff0f499f25\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"5.10.67\", \"lessThan\": \"5.11\", \"versionType\": \"semver\"}, {\"status\": \"affected\", \"version\": \"5.13.19\", \"lessThan\": \"5.14\", \"versionType\": \"semver\"}], \"programFiles\": [\"net/sunrpc/sysfs.c\", \"net/sunrpc/xprtsock.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"5.14\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"5.14\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"5.15.209\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.15.*\"}, {\"status\": \"unaffected\", \"version\": \"5.16.10\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.16.*\"}, {\"status\": \"unaffected\", \"version\": \"5.17\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"net/sunrpc/sysfs.c\", \"net/sunrpc/xprtsock.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/fdc42287ae3f8a35cc2098307f52d7864b4bc8ed\"}, {\"url\": \"https://git.kernel.org/stable/c/9482ab4540f5bcc869b44c067ae99b5fca16bd07\"}, {\"url\": \"https://git.kernel.org/stable/c/b49ea673e119f59c71645e2f65b3ccad857c90ee\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nSUNRPC: lock against -\u003esock changing during sysfs read\\n\\n-\u003esock can be set to NULL asynchronously unless -\u003erecv_mutex is held.\\nSo it is important to hold that mutex.
