CVE-2024-47749 (GCVE-0-2024-47749)

Title
RDMA/cxgb4: Added NULL check for lookup_atid
Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/cxgb4: Added NULL check for lookup_atid
The lookup_atid() function can return NULL if the ATID is
invalid or does not exist in the identifier table, which
could lead to dereferencing a null pointer without a
check in the `act_establish()` and `act_open_rpl()` functions.
Add a NULL check to prevent null pointer dereferencing.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

Atid-table exhaustion, which makes the freed slot read back as NULL, is likewise inducible by flooding concurrent connects.\nPR:N - `act_establish()` and `act_open_rpl()` run at TCP handshake completion/failure, long before MPA negotiation or any credential exchange, so the peer driving the condition is entirely unauthenticated. No privileges on the target are needed for the remote side of the attack.\nUI:N - No victim action is required \u2014 the connection attempts are made by already-running RDMA ULPs or reconnect loops, and the CPL processing happens asynchronously in the `iw_cxgb4` workqueue.\nS:U - The NULL dereference crashes the kernel that contains the flaw; no security authority boundary such as a VM or IOMMU domain is crossed.\nC:N - The dereference is of a NULL `struct c4iw_ep *` at small member offsets (`com.mutex`, `dst`, `com.local_addr`), all below `mmap_min_addr`, so it faults immediately with no attacker-mapped page and yields no read primitive or information disclosure.\nI:N - No memory is written through the NULL pointer before the fault, and the bug provides no write primitive or control-flow hijack \u2014 it is a pure crash.\nA:H - The dereference produces a kernel oops in workqueue context, which is a full panic on `panic_on_oops` systems; even absent that, the ordered `iw_cxgb4` workqueue is wedged, stalling all RDMA connection management for the adapter."

Title
PCI: keystone: Fix if-statement expression in ks_pcie_quirk()
Summary
In the Linux kernel, the following vulnerability has been resolved:
PCI: keystone: Fix if-statement expression in ks_pcie_quirk()
This code accidentally uses && where || was intended. It potentially
results in a NULL dereference.
Thus, fix the if-statement expression to use the correct condition.

Title
nilfs2: fix potential oob read in nilfs_btree_check_delete()
Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix potential oob read in nilfs_btree_check_delete()
The function nilfs_btree_check_delete(), which checks whether degeneration
to direct mapping occurs before deleting a b-tree entry, causes memory
access outside the block buffer when retrieving the maximum key if the
root node has no entries.
This does not usually happen because b-tree mappings with 0 child nodes
are never created by mkfs.nilfs2 or nilfs2 itself. However, it can happen
if the b-tree root node read from a device is configured that way, so fix
this potential issue by adding a check for that case.
Severity

Title
tpm: Clean up TPM space after command failure
Summary
In the Linux kernel, the following vulnerability has been resolved:
tpm: Clean up TPM space after command failure
tpm_dev_transmit prepares the TPM space before attempting command
transmission. However if the command fails no rollback of this
preparation is done. This can result in transient handles being leaked
if the device is subsequently closed with no further commands performed.
Fix this by flushing the space in the event of command transmission
failure.

Title
scsi: elx: libefc: Fix potential use after free in efc_nport_vport_del()
Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: elx: libefc: Fix potential use after free in efc_nport_vport_del()
The kref_put() function will call nport->release if the refcount drops to
zero. The nport->release release function is _efc_nport_free() which frees
"nport". But then we dereference "nport" on the next line which is a use
after free. Re-order these lines to avoid the use after free.

Title
x86/sgx: Fix deadlock in SGX NUMA node search
Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/sgx: Fix deadlock in SGX NUMA node search
When the current node doesn't have an EPC section configured by firmware
and all other EPC sections are used up, CPU can get stuck inside the
while loop that looks for an available EPC page from remote nodes
indefinitely, leading to a soft lockup. Note how nid_of_current will
never be equal to nid in that while loop because nid_of_current is not
set in sgx_numa_mask.
Also worth mentioning is that it's perfectly fine for the firmware not
to setup an EPC section on a node. While setting up an EPC section on
each node can enhance performance, it is not a requirement for
functionality.
Rework the loop to start and end on *a* node that has SGX memory. This
avoids the deadlock looking for the current SGX-lacking node to show up
in the loop when it never will.

Title
efistub/tpm: Use ACPI reclaim memory for event log to avoid corruption
Summary
In the Linux kernel, the following vulnerability has been resolved:
efistub/tpm: Use ACPI reclaim memory for event log to avoid corruption
The TPM event log table is a Linux specific construct, where the data
produced by the GetEventLog() boot service is cached in memory, and
passed on to the OS using an EFI configuration table.
The use of EFI_LOADER_DATA here results in the region being left
unreserved in the E820 memory map constructed by the EFI stub, and this
is the memory description that is passed on to the incoming kernel by
kexec, which is therefore unaware that the region should be reserved.
Even though the utility of the TPM2 event log after a kexec is
questionable, any corruption might send the parsing code off into the
weeds and crash the kernel. So let's use EFI_ACPI_RECLAIM_MEMORY
instead, which is always treated as reserved by the E820 conversion
logic.

Title
vhost/scsi: null-ptr-dereference in vhost_scsi_get_req()
Summary
In the Linux kernel, the following vulnerability has been resolved:
vhost/scsi: null-ptr-dereference in vhost_scsi_get_req()
Since commit 3f8ca2e115e5 ("vhost/scsi: Extract common handling code
from control queue handler") a null pointer dereference bug can be
triggered when guest sends an SCSI AN request.
In vhost_scsi_ctl_handle_vq(), `vc.target` is assigned with
`&v_req.tmf.lun[1]` within a switch-case block and is then passed to
vhost_scsi_get_req() which extracts `vc->req` and `tpg`. However, for
a `VIRTIO_SCSI_T_AN_*` request, tpg is not required, so `vc.target` is
set to NULL in this branch. Later, in vhost_scsi_get_req(),
`vc->target` is dereferenced without being checked, leading to a null
pointer dereference bug. This bug can be triggered from guest.
When this bug occurs, the vhost_worker process is killed while holding
`vq->mutex` and the corresponding tpg will remain occupied
indefinitely.
Below is the KASAN report:

However, for\na `VIRTIO_SCSI_T_AN_*` request, tpg is not required, so `vc.target` is\nset to NULL in this branch. Later, in vhost_scsi_get_req(),\n`vc-\u003etarget` is dereferenced without being checked, leading to a null\npointer dereference bug. This bug can be triggered from guest.\n\nWhen this bug occurs, the vhost_worker process is killed while holding\n`vq-\u003emutex` and the corresponding tpg will remain occupied\nindefinitely.\n\nBelow is the KASAN report:\nOops: general protection fault, probably for non-canonical address\n0xdffffc0000000000: 0000 [#1] PREEMPT SMP KASAN NOPTI\nKASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007]\nCPU: 1 PID: 840 Comm: poc Not tainted 6.10.0+ #1\nHardware name: QEMU Ubuntu 24.04 PC (i440FX + PIIX, 1996), BIOS\n1.16.3-debian-1.16.3-2 04/01/2014\nRIP: 0010:vhost_scsi_get_req+0x165/0x3a0\nCode: 00 fc ff df 48 89 fa 48 c1 ea 03 80 3c 02 00 0f 85 2b 02 00 00\n48 b8 00 00 00 00 00 fc ff df 4d 8b 65 30 4c 89 e2 48 c1 ea 03 \u003c0f\u003e b6\n04 02 4c 89 e2 83 e2 07 38 d0 7f 08 84 c0 0f 85 be 01 00 00\nRSP: 0018:ffff888017affb50 EFLAGS: 00010246\nRAX: dffffc0000000000 RBX: ffff88801b000000 RCX: 0000000000000000\nRDX: 0000000000000000 RSI: 0000000000000000 RDI: ffff888017affcb8\nRBP: ffff888017affb80 R08: 0000000000000000 R09: 0000000000000000\nR10: 0000000000000000 R11: 0000000000000000 R12: 0000000000000000\nR13: ffff888017affc88 R14: ffff888017affd1c R15: ffff888017993000\nFS: 000055556e076500(0000) GS:ffff88806b100000(0000) knlGS:0000000000000000\nCS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\nCR2: 00000000200027c0 CR3: 0000000010ed0004 CR4: 0000000000370ef0\nCall Trace:\n \u003cTASK\u003e\n ? show_regs+0x86/0xa0\n ? die_addr+0x4b/0xd0\n ? exc_general_protection+0x163/0x260\n ? asm_exc_general_protection+0x27/0x30\n ? vhost_scsi_get_req+0x165/0x3a0\n vhost_scsi_ctl_handle_vq+0x2a4/0xca0\n ? __pfx_vhost_scsi_ctl_handle_vq+0x10/0x10\n ? __switch_to+0x721/0xeb0\n ? __schedule+0xda5/0x5710\n ? __kasan_check_write+0x14/0x30\n ? _raw_spin_lock+0x82/0xf0\n vhost_scsi_ctl_handle_kick+0x52/0x90\n vhost_run_work_list+0x134/0x1b0\n vhost_task_fn+0x121/0x350\n...\n \u003c/TASK\u003e\n---[ end trace 0000000000000000 ]---\n\nLet\u0027s add a check in vhost_scsi_get_req.\n\n[whitespace fixes]"

Title
tracing/timerlat: Fix a race during cpuhp processing
Summary
In the Linux kernel, the following vulnerability has been resolved:
tracing/timerlat: Fix a race during cpuhp processing
There is another found exception that the "timerlat/1" thread was
scheduled on CPU0, and lead to timer corruption finally:
```

```
After tracing the scheduling event, it was discovered that the migration
of the "timerlat/1" thread was performed during thread creation. Further
analysis confirmed that it is because the CPU online processing for
osnoise is implemented through workers, which is asynchronous with the
offline processing. When the worker was scheduled to create a thread, the
CPU may has already been removed from the cpu_online_mask during the offline
process, resulting in the inability to select the right CPU:
T1 | T2
[CPUHP_ONLINE] | cpu_device_down()
osnoise_hotplug_workfn() |
| cpus_write_lock()
| takedown_cpu(1)
| cpus_write_unlock()
[CPUHP_OFFLINE] |
cpus_read_lock() |
start_kthread(1) |
cpus_read_unlock() |
To fix this, skip online processing if the CPU is already offline.
