CVE-2025-27021

The misconfiguration in the sudoers configuration of the operating system in
 Infinera G42 version R6.1.3 allows low privileged OS users to 
read/write physical memory via devmem command line tool. 
This could 
allow sensitive information disclosure, denial of service, and privilege 
escalation by tampering with kernel memory.


Details: The output of "sudo -l" reports the presence of "devmem" command 
executable as super user without using a password. This command allows 
to read and write an arbitrary memory area of the target device, 
specifying an absolute address.
