Vulnerability from github – Published: 2025-03-17 18:31 – Updated: 2025-03-17 18:31In the Linux kernel, the following vulnerability has been resolved:
HID: elan: Fix potential double free in elan_input_configured
'input' is a managed resource allocated with devm_input_allocate_device(), so there is no need to call input_free_device() explicitly or there will be a double free.
According to the doc of devm_input_allocate_device(): * Managed input devices do not need to be explicitly unregistered or * freed as it will be done automatically when owner device unbinds from * its driver (or binding fails).

GHSA-9M47-29XF-M969
Vulnerability from github – Published: 2026-01-15 21:31 – Updated: 2026-01-15 21:31A Double Free vulnerability in the flow processing daemon (flowd) of Juniper Networks Junos OS on SRX and MX Series allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS). On all SRX and MX Series platforms, when during TCP session establishment a specific sequence of packets is encountered a double free happens. This causes flowd to crash and the respective FPC to restart.
This issue affects Junos OS on SRX and MX Series:
- all versions before 22.4R3-S7,
- 23.2 versions before 23.2R2-S3,
- 23.4 versions before 23.4R2-S4,
- 24.2 versions before 24.2R2.

}
Mitigation
Choose a language that provides automatic memory management.
Mitigation
Ensure that each allocation is freed only once. After freeing a chunk, set the pointer to NULL to ensure the pointer cannot be freed again. In complicated error conditions, be sure that clean-up routines respect the state of allocation properly. If the language is object oriented, ensure that object destructors delete each chunk of memory only once.
Mitigation
Use a static analysis tool to find double free instances.
No CAPEC attack patterns related to this CWE.
