CVE-2023-52612: crypto: scomp - fix req->dst buffer overflow

Noroxi assessment

Priority: Monitor (action score 31/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.27% (FIRST EPSS).
Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
Fixed version: Linux Linux 1142d65c5b881590962ad763f94505b6dd67d2fe, 4518dc468cdd796757190515a9be7408adc8911e, 4df0c942d04a67df174195ad8082f6e30e7f71a5.
Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 1142d65c5b881590962ad763f94505b6dd67d2fe, 4518dc468cdd796757190515a9be7408adc8911e, 4df0c942d04a67df174195ad8082f6e30e7f71a5 or later.

Weakness class (CWE)

CWE-120 · Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')

CVSS vector

CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Root cause

When data is copied, the source length is not compared with the size of the destination buffer. Excess data overwrites adjacent memory.
