HI,

please check the below link.

https://www.juniper.net/security/aut...vuln17587.html

Description:

The Linux kernel is prone to vulnerabilities regarding access to shared memory.

These vulnerabilities occur when shared-memory permissions are not properly validated.

The first issue allows attackers to replace portions of files containined in 'tmpfs' filesystems with zeros. Attackers utilize the 'madvise' system call to exploit this issue.

The second issue allows attackers to modify readonly portions of shared memory. Attackers utilize the 'mprotect' system call to exploit this issue.

An attacker can exploit these issues to possibly corrupt applications and their data when the applications use temporary files or shared memory.
