Vulnerability from cvelistv5
Published

Severity ?
8.1 (High) - CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: afs: Increase buffer size in afs_update_volume_status() The max length of volume->vid value is 20 characters. So increase idbuf[] size up to 24 to avoid overflow. Found by Linux Verification Center (linuxtesting.org) with SVACE. [DH: Actually, it's 20 + NUL, so increase it to 24 and use snprintf()]

              "value": "AV:N - The value formatted into the undersized stack buffer originates entirely from a remote Volume Location server\u0027s `VL.GetEntryByNameU` reply (`ntohl(uvldb-\u003evolumeId[i])`, fs/afs/vlclient.c:77), and the call into `afs_update_volume_status()` is itself forced on demand by a remote fileserver returning VNOVOL/VMOVED abort codes (fs/afs/rotate.c:247,387). AFS VL traffic is unauthenticated rxrpc over UDP, so a rogue cell server or an on-path response spoofer reaches this code across the network.\nAC:H - Overflowing `idbuf[16]` requires `volume-\u003evid` to exceed 10 decimal digits, but the on-wire `volumeId[]` field is `__be32` (fs/afs/afs_vl.h:123) and is the sole source of `volume-\u003evid`, capping it at `4294967295`. The wire-format width is a hard constraint entirely beyond the attacker\u0027s control, so no attainable input triggers the write.\nPR:N - The attacker is the VL server (or a network entity spoofing its unauthenticated replies) and holds no account, credential, or capability on the target host. No local privilege on the victim is consumed anywhere along the `afs_select_fileserver` \u2192 `afs_check_volume_status` \u2192 `afs_update_volume_status` path.\nUI:N - On a configured AFS client `/afs` is already mounted at boot, and the volume-status refresh fires from routine background revalidation and from server-supplied VMOVED/VNOVOL responses without any victim action. The attacker drives the update himself via the fileserver\u0027s abort codes.\nS:U - Any corruption is confined to the AFS client\u0027s own kernel stack frame within the same kernel security authority. No VM, hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - A stack write past `idbuf` overwrites the adjacent locals in the same frame \u2014 the `new`/`old`/`discard`/`vldb` pointers and `idsz` \u2014 and corrupting `vldb` or `idsz` redirects the subsequent `memcmp`/`memcpy` of the volume name and the `afs_alloc_server_list()` walk, yielding an attacker-influenced kernel read. Per kernel guidance, memory corruption leverageable for disclosure is scored High.\nI:H - This is an out-of-bounds stack write, which per kernel guidance is High: the clobbered pointers are dereferenced and written through immediately afterwards (`memcpy(volume-\u003ename, vldb-\u003ename, AFS_MAXVOLNAME)`, `rcu_assign_pointer(volume-\u003eservers, new)`), giving a path to controlled kernel memory modification and control-flow influence.\nA:H - On any stack-protector kernel the 5-byte overrun smashes the canary and `__stack_chk_fail()` panics the machine; without it, the corrupted `vldb`/`new`/`old` pointers are dereferenced and freed (`kfree(vldb)`, `afs_put_serverlist()`), producing an oops. Either outcome is a full kernel crash."

AFS VL traffic is unauthenticated rxrpc over UDP, so a rogue cell server or an on-path response spoofer reaches this code across the network.\\nAC:H - Overflowing `idbuf[16]` requires `volume-\u003evid` to exceed 10 decimal digits, but the on-wire `volumeId[]` field is `__be32` (fs/afs/afs_vl.h:123) and is the sole source of `volume-\u003evid`, capping it at `4294967295`. The wire-format width is a hard constraint entirely beyond the attacker\u0027s control, so no attainable input triggers the write.\\nPR:N - The attacker is the VL server (or a network entity spoofing its unauthenticated replies) and holds no account, credential, or capability on the target host. No local privilege on the victim is consumed anywhere along the `afs_select_fileserver` \\u2192 `afs_check_volume_status` \\u2192 `afs_update_volume_status` path.\\nUI:N - On a configured AFS client `/afs` is already mounted at boot, and the volume-status refresh fires from routine background revalidation and from server-supplied VMOVED/VNOVOL responses without any victim action. The attacker drives the update himself via the fileserver\u0027s abort codes.\\nS:U - Any corruption is confined to the AFS client\u0027s own kernel stack frame within the same kernel security authority. No VM, hypervisor, IOMMU, or sandbox boundary is crossed.\\nC:H - A stack write past `idbuf` overwrites the adjacent locals in the same frame \\u2014 the `new`/`old`/`discard`/`vldb` pointers and `idsz` \\u2014 and corrupting `vldb` or `idsz` redirects the subsequent `memcmp`/`memcpy` of the volume name and the `afs_alloc_server_list()` walk, yielding an attacker-influenced kernel read. Per kernel guidance, memory corruption leverageable for disclosure is scored High.\\nI:H - This is an out-of-bounds stack write, which per kernel guidance is High: the clobbered pointers are dereferenced and written through immediately afterwards (`memcpy(volume-\u003ename, vldb-\u003ename, AFS_MAXVOLNAME)`, `rcu_assign_pointer(volume-\u003eservers, new)`), giving a path to controlled kernel memory modification and control-flow influence.\\nA:H - On any stack-protector kernel the 5-byte overrun smashes the canary and `__stack_chk_fail()` panics the machine; without it, the corrupted `vldb`/`new`/`old` pointers are dereferenced and freed (`kfree(vldb)`, `afs_put_serverlist()`), producing an oops.
