Name of the Vulnerable Software and Affected Versions Buildroot versions prior to 0b2967e Buildroot version 2024.02.2 and later are not affected, but all versions before 0b2967e are vulnerable. Since 2024.02.2 is the fixed version, we list all versions prior to 0b2967e as vulnerable.

Description The issue is related to the lack of the sticky bit for the /dev/shm directory in Buildroot before version 0b2967e. A fix was released in version 2024.02.2.

Recommendations For Buildroot versions prior to 0b2967e, update to version 2024.02.2 or later to resolve the issue. As a temporary workaround, consider setting the sticky bit for the /dev/shm directory manually until a patch is applied.
