Starting in Buildroot 2011.08, its default /etc/fstab included an entry for /dev/shm with incorrect permissons (sticky bit not set). (CWE-276) Buildroot 2017.08 removed this entry for systems using systemd, and it has never been included for systems using OpenRC. So this only affects Buildroot-built systems that use sysvinit, and some older systems that use systemd.[...] This has been assigned CVE-2024-34455.
Thanks for th efeedback. The fix has already been committed, with commit 0b2967e158 (package/skeleton-init-sysv: Set sticky bit on /dev/shm) that I applied on 2024-04-11. Regards, Yann E.
