Junos OS

Hi,

I'm using JunOS 21.4R3-S11.  Some vulnerability like CVE 2026-21910 mentioned that it is affecting versions before S21.4R3-S12:

all versions before 21.4R3-S12, 
all versions of 22.2
from 22.4 before 22.4R3-S8, 
from 23.2 before 23.2R2-S5, 
from 23.4 before 23.4R2-S5, 
from 24.2 before 24.2R2-S3,
from 24.4 before 24.4R2.

while some vulnerability like CVE 2026-21921 mentioned that it is affecting all versions before 22.4R3 S8 and not mentioning 22.2 & 21.4 versions: 

all versions before 22.4R3-S8,
23.2 versions before 23.2R2-S5,
23.4 versions before 23.4R2;

Therefore, would like to clarify if 21.4 series JunOS is also affected by CVE 2026-21921?

Regards,
