Vulnerability from github – Published: 2024-08-21 09:31 – Updated: 2024-08-29 03:30

Details
In the Linux kernel, the following vulnerability has been resolved:
efi: fix NULL-deref in init error path
In cases where runtime services are not supported or have been disabled, the runtime services workqueue will never have been allocated.
Do not try to destroy the workqueue unconditionally in the unlikely event that EFI initialisation fails to avoid dereferencing a NULL pointer.

Vulnerability from github – Published: 2026-10-09 15:31 – Updated: 2026-10-09 15:31
VLAI
Details
A NULL pointer dereference in the illumos Network Auto-Magic daemon (nwamd) allows a local user to crash the daemon. nwamd_door_switch() in usr/src/cmd/cmd-inet/lib/nwamd/door_if.c writes to the caller's request structure before checking that a request was supplied, and before checking the caller's credentials. Because the nwamd door at /etc/svc/volatile/nwam/nwam_door is accessible to all local users, an unprivileged user can issue a door_call() with no argument data to crash nwamd; repeated calls place the svc:/network/physical:nwam service into maintenance, stopping automatic network configuration. nwamd runs only when svc:/network/physical:nwam is enabled, which is not the default. The flaw has existed since 2010 (illumos-gate commit 6ba597c5), and affects any illumos distribution prior to illumos-gate commit 0f1064d9.

Mitigation MIT-56
Implementation
For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].
Mitigation
Requirements
Select a programming language that is not susceptible to these issues.
Mitigation
Implementation
Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
Mitigation
Architecture and Design
Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.
Mitigation
Implementation
Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
