GHSA-7FMQ-QW39-X2X2

Vulnerability from github – Published: 2025-05-01 15:31 – Updated: 2025-11-10 21:30
VLAI
Details

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

drm/drv: Fix potential memory leak in drm_dev_init()

drm_dev_init() will add drm_dev_init_release() as a callback. When drmm_add_action() failed, the release function won't be added. As the result, the ref cnt added by device_get() in drm_dev_init() won't be put by drm_dev_init_release(), which leads to the memleak. Use drmm_add_action_or_reset() instead of drmm_add_action() to prevent memleak.

Vulnerability from github – Published: 2025-04-09 21:31 – Updated: 2025-04-09 21:31
VLAI
Details

A Missing Release of Memory after Effective Lifetime vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent, unauthenticated attacker to cause an FPC to crash, leading to Denial of Service (DoS).

On all Junos OS and Junos OS Evolved platforms, in an EVPN-VXLAN scenario, when specific ARP packets are received on an IPv4 network, or specific NDP packets are received on an IPv6 network, kernel heap memory leaks, which eventually leads to an FPC crash and restart.

This issue does not affect MX Series platforms. Heap size growth on FPC can be seen using below command.

This issue affects Junos OS:

  • All versions before 21.2R3-S7,
  • 21.4 versions before 21.4R3-S4,
  • 22.2 versions before 22.2R3-S1, 
  • 22.3 versions before 22.3R3-S1, 
  • 22.4 versions before 22.4R2-S2, 22.4R3.

and Junos OS Evolved:

  • All versions before 21.2R3-S7-EVO,
  • 21.4-EVO versions before 21.4R3-S4-EVO,
  • 22.2-EVO versions before 22.2R3-S1-EVO, 

  • 22.3-EVO versions before 22.3R3-S1-EVO,

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

octeon_ep: Fix memory leak in octep_device_setup()

In octep_device_setup(), if octep_ctrl_net_init() fails, the function returns directly without unmapping the mapped resources and freeing the allocated configuration memory.

Fix this by jumping to the unsupported_dev label, which performs the necessary cleanup. This aligns with the error handling logic of other paths in this function.

Compile tested only. Issue found using a prototype static analysis tool and code review.

Details

Some ZTE products have a DoS vulnerability. Due to the improper handling of memory release in some specific scenarios, a remote attacker can trigger the vulnerability by performing a series of operations, resulting in memory leak, which may eventually lead to device denial of service. This affects: ZXR10 9904, ZXR10 9908, ZXR10 9916, ZXR10 9904-S, ZXR10 9908-S; all versions up to V1.01.10.B12.

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

kernel/fail_function: fix memory leak with using debugfs_lookup()

When calling debugfs_lookup() the result must have dput() called on it, otherwise the memory will leak over time. To make things simpler, just call debugfs_lookup_and_remove() instead which handles all of the logic at once.

Vulnerability from github – Published: 2024-12-27 15:31 – Updated: 2025-01-06 18:31

Details

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

iommu/vt-d: Fix qi_batch NULL pointer with nested parent domain

The qi_batch is allocated when assigning cache tag for a domain. While for nested parent domain, it is missed. Hence, when trying to map pages to the nested parent, NULL dereference occurred. Also, there is potential memleak since there is no lock around domain->qi_batch allocation.

To solve it, add a helper for qi_batch allocation, and call it in both the __cache_tag_assign_domain() and __cache_tag_assign_parent_domain().

Mitigation MIT-41
Implementation

Strategy: Libraries or Frameworks

  • Choose a language or tool that provides automatic memory management, or makes manual memory management less error-prone.
  • For example, glibc in Linux provides protection against free of invalid pointers.
  • When using Xcode to target OS X or iOS, enable automatic reference counting (ARC) [REF-391].
  • To help correctly and consistently manage memory when programming in C++, consider using a smart pointer class such as std::auto_ptr (defined by ISO/IEC ISO/IEC 14882:2003), std::shared_ptr and std::unique_ptr (specified by an upcoming revision of the C++ standard, informally referred to as C++ 1x), or equivalent solutions such as Boost.
Mitigation
Architecture and Design

Use an abstraction library to abstract away risky APIs. Not a complete solution.

Mitigation
Architecture and Design Build and Compilation

Consider using the Boehm-Demers-Weiser garbage collector (bdwgc), which can help avoid leaks.
