Details

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

PM: domains: 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.

GHSA-9P4V-567M-9GGG

Vulnerability from github – Published: 2026-04-10 00:30 – Updated: 2026-04-10 00:30
VLAI
Details

A Missing Release of Memory after Effective Lifetime vulnerability in the BroadBand Edge subscriber management daemon (bbe-smgd) of Juniper Networks Junos OS on MX Series allows an adjacent, unauthenticated attacker to cause a Denial of Service (DoS).

If the authentication packet-type option is configured and a received packet does not match that packet type, the memory leak occurs. When all memory

available to bbe-smgd has been consumed, no new subscribers will be able to login.

The memory utilization of bbe-smgd can be monitored with the following show command:

user@host> show system processes extensive | match bbe-smgd

The below log message can be observed when this limit has been reached:

bbesmgd[]: %DAEMON-3-SMD_DPROF_RSMON_ERROR: Resource unavailability, Reason: Daemon Heap Memory exhaustion

This issue affects Junos OS on MX Series: * all versions before 22.4R3-S8, * 23.2 versions before 23.2R2-S5, * 23.4 versions before 23.4R2-S6, * 24.2 versions before 24.2R2-S2, * 24.4 versions before 24.4R2, * 25.2 versions before 25.2R2.

Vulnerability from github – Published: 2024-07-10 09:30 – Updated: 2026-05-12 12:32
VLAI
Details

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

ipv6: sr: fix memleak in seg6_hmac_init_algo

seg6_hmac_init_algo returns without cleaning up the previous allocations if one fails, so it's going to leak all that memory and the crypto tfms.

Update seg6_hmac_exit to only free the memory when allocated, so we can reuse the code directly.

Details

A Missing Release of Memory after Effective Lifetime vulnerability in the Flow Processing Daemon (flowd) of Juniper Networks Junos OS allows a network-based, unauthenticated attacker to cause a Denial of Service (DoS). In an IPsec VPN environment, a memory leak will be seen if a DH or ECDH group is configured. Eventually the flowd process will crash and restart. This issue affects Juniper Networks Junos OS on SRX Series: All versions prior to 19.3R3-S7; 19.4 versions prior to 19.4R2-S8, 19.4R3-S10; 20.2 versions prior to 20.2R3-S6; 20.3 versions prior to 20.3R3-S5; 20.4 versions prior to 20.4R3-S5; 21.1 versions prior to 21.1R3-S4; 21.2 versions prior to 21.2R3; 21.3 versions prior to 21.3R3; 21.4 versions prior to 21.4R2.

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

net: fec: fix the potential memory leak in fec_enet_init()

If the memory allocated for cbd_base is failed, it should free the memory allocated for the queues, otherwise it causes memory leak.

And if the memory allocated for the queues is failed, it can return error directly.

GHSA-9Q42-QQ54-FWVJ

Vulnerability from github – Published: 2025-02-27 03:34 – Updated: 2025-03-05 21:32
VLAI
Details

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

iommu: Fix potential memory leak in iopf_queue_remove_device()

The iopf_queue_remove_device() helper removes a device from the per-iommu iopf queue when PRI is disabled on the device. It responds to all outstanding iopf's with an IOMMU_PAGE_RESP_INVALID code and detaches the device from the queue.

However, it fails to release the group structure that represents a group of iopf's awaiting for a response after responding to the hardware. This can cause a memory leak if iopf_queue_remove_device() is called with pending iopf's.

Fix it by calling iopf_free_group() after the iopf group is responded.

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.
