Vulnerability from github – Published: 2021-05-21 14:26 – Updated: 2024-10-31 21:24

Summary

Null pointer dereference in TFLite's `Reshape` operator

Details

Impact

The fix for CVE-2020-15209 missed the case when the target shape of Reshape operator is given by the elements of a 1-D tensor. As such, the fix for the vulnerability allowed passing a null-buffer-backed tensor with a 1D shape:

if (tensor->data.raw == nullptr && tensor->bytes > 0) {
  if (registration.builtin_code == kTfLiteBuiltinReshape && i == 1) {
    // In general, having a tensor here with no buffer will be an error.
    // However, for the reshape operator, the second input tensor is only
    // used for the shape, not for the data. Thus, null buffer is ok.
    continue;
  } else {
    // In all other cases, we need to return an error as otherwise we will
    // trigger a null pointer dereference (likely).
    ReportError("Input tensor %d lacks data", tensor_index);
    return kTfLiteError;
  }
}

Patches

We have patched the issue in GitHub commit f8378920345f4f4604202d4ab15ef64b2aceaa16.

The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3 and TensorFlow 2.1.4, as these are also affected and still in supported range.

GHSA-JJRX-X936-XWH4

Vulnerability from github – Published: 2024-01-12 03:30 – Updated: 2024-01-12 03:30

Details

A NULL Pointer Dereference vulnerability in Juniper Networks Junos OS Evolved on ACX7024, ACX7100-32C and ACX7100-48L allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS).

If a specific IPv4 UDP packet is received and sent to the Routing Engine (RE) packetio crashes and restarts which causes a momentary traffic interruption. Continued receipt of such packets will lead to a sustained DoS.

This issue does not happen with IPv6 packets.

This issue affects Juniper Networks Junos OS Evolved on ACX7024, ACX7100-32C and ACX7100-48L:

21.4-EVO versions earlier than 21.4R3-S6-EVO;
22.1-EVO versions earlier than 22.1R3-S5-EVO;
22.2-EVO versions earlier than 22.2R2-S1-EVO, 22.2R3-EVO;
22.3-EVO versions earlier than 22.3R2-EVO.

This issue does not affect Juniper Networks Junos OS Evolved versions earlier than 21.4R1-EVO.

Severity

7.5 (High)

GHSA-JM8P-GGG3-GFGW

Vulnerability from github – Published: 2025-10-04 09:30 – Updated: 2026-01-27 21:31

Details

In the Linux kernel, the following vulnerability has been resolved:

crypto: ccp - Always pass in an error pointer to __sev_platform_shutdown_locked()

When

9770b428b1a2 ("crypto: ccp - Move dev_info/err messages for SEV/SNP init and shutdown")

moved the error messages dumping so that they don't need to be issued by the callers, it missed the case where __sev_firmware_shutdown() calls __sev_platform_shutdown_locked() with a NULL argument which leads to a NULL ptr deref on the shutdown path, during suspend to disk:

#PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 0 P4D 0 Oops: Oops: 0000 [#1] SMP NOPTI CPU: 0 UID: 0 PID: 983 Comm: hib.sh Not tainted 6.17.0-rc4+ #1 PREEMPT(voluntary) Hardware name: Supermicro Super Server/H12SSL-i, BIOS 2.5 09/08/2022 RIP: 0010:__sev_platform_shutdown_locked.cold+0x0/0x21 [ccp]

That rIP is:

00000000000006fd <__sev_platform_shutdown_locked.cold>: 6fd: 8b 13 mov (%rbx),%edx 6ff: 48 8b 7d 00 mov 0x0(%rbp),%rdi 703: 89 c1 mov %eax,%ecx

Code: 74 05 31 ff 41 89 3f 49 8b 3e 89 ea 48 c7 c6 a0 8e 54 a0 41 bf 92 ff ff ff e8 e5 2e 09 e1 c6 05 2a d4 38 00 01 e9 26 af ff ff <8b> 13 48 8b 7d 00 89 c1 48 c7 c6 18 90 54 a0 89 44 24 04 e8 c1 2e RSP: 0018:ffffc90005467d00 EFLAGS: 00010282 RAX: 00000000ffffff92 RBX: 0000000000000000 RCX: 0000000000000000 ^^^^^^^^^^^^^^^^ and %rbx is nice and clean.

Call Trace: __sev_firmware_shutdown.isra.0 sev_dev_destroy psp_dev_destroy sp_destroy pci_device_shutdown device_shutdown kernel_power_off hibernate.cold state_store kernfs_fop_write_iter vfs_write ksys_write do_syscall_64 entry_SYSCALL_64_after_hwframe

Pass in a pointer to the function-local error var in the caller.

With that addressed, suspending the ccp shows the error properly at least:

ccp 0000:47:00.1: sev command 0x2 timed out, disabling PSP ccp 0000:47:00.1: SEV: failed to SHUTDOWN error 0x0, rc -110 SEV-SNP: Leaking PFN range 0x146800-0x146a00 SEV-SNP: PFN 0x146800 unassigned, dumping non-zero entries in 2M PFN region: [0x146800 - 0x146a00] ... ccp 0000:47:00.1: SEV-SNP firmware shutdown failed, rc -16, error 0x0 ACPI: PM: Preparing to enter system sleep state S5 kvm: exiting hardware virtualization reboot: Power down

Btw, this driver is crying to be cleaned up to pass in a proper I/O struct which can be used to store information between the different functions, otherwise stuff like that will happen in the future again.

Severity

5.5 (Medium)
