CVE-2019-11487

26
FAUCET Score

CVE-2019-11487 is a Linux kernel vulnerability, affecting versions before 5.1-rc5, where a reference count overflow in memory management can lead to use-after-free issues, particularly when approximately 140 GiB of RAM is present and FUSE requests are involved. This vulnerability has a CVSS score of 7.8 (High), indicating a local attack vector with low complexity, allowing a low-privileged attacker to achieve high confidentiality, integrity, and availability impacts. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage, suggesting it is not widely targeted.
