GHSA-32C5-Q8CJ-XX83
Vulnerability from github – Published: 2025-05-01 15:31 – Updated: 2025-05-07 15:31In the Linux kernel, the following vulnerability has been resolved:
net: wwan: mhi: fix memory leak in mhi_mbim_dellink
MHI driver registers network device without setting the needs_free_netdev flag, and does NOT call free_netdev() when unregisters network device, which causes a memory leak.
This patch sets needs_free_netdev to true when registers network device, which makes netdev subsystem call free_netdev() automatically after unregister_netdevice().

Vulnerability from github – Published: 2024-06-20 12:31 – Updated: 2024-09-18 18:30In the Linux kernel, the following vulnerability has been resolved:
block: fix memory leak in disk_register_independent_access_ranges
kobject_init_and_add() takes reference even when it fails. According to the doc of kobject_init_and_add()
If this function returns an error, kobject_put() must be called to properly clean up the memory associated with the object.
Fix this issue by adding kobject_put(). Callback function blk_ia_ranges_sysfs_release() in kobject_put() can handle the pointer "iars" properly.

GHSA-347M-W2V2-FMV3
Vulnerability from github – Published: 2022-01-20 00:01 – Updated: 2022-02-02 00:02A Missing Release of Memory after Effective Lifetime vulnerability in the Public Key Infrastructure daemon (pkid) of Juniper Networks Junos OS allows an unauthenticated networked attacker to cause Denial of Service (DoS). In a scenario where Public Key Infrastructure (PKI) is used in combination with Certificate Revocation List (CRL), if the CRL fails to download the memory allocated to store the CRL is not released. Repeated occurrences will eventually consume all available memory and lead to an inoperable state of the affected system causing a DoS.

Mitigation MIT-41
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
Use an abstraction library to abstract away risky APIs. Not a complete solution.
Mitigation
Consider using the Boehm-Demers-Weiser garbage collector (bdwgc), which can help avoid leaks.
