CVE-2018-7273

30
FAUCET Score

CVE-2018-7273 is a Linux kernel vulnerability affecting versions through 4.15.4, where the floppy driver inadvertently leaks kernel function and global variable addresses via printk calls. This information, accessible through dmesg, allows a local attacker to map kernel memory and potentially bypass security mechanisms like KASLR. Rated Medium (CVSS 5.5), the vulnerability requires local access and has a high impact on confidentiality, but no impact on integrity or availability. While not actively exploited in the wild, a Proof-of-Concept (PoC) exploit exists on ExploitDB, and there is some community discussion, indicating awareness among researchers.
