CVE-2024-27045: drm/amd/display: Fix a potential buffer overflow in 'dp_dsc_clock_en_read()'

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: 0.30% (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 440f059837418fac1695b65d3ebc6080d33be877, 4b09715f1504f1b6e8dff0e9643630610bc05141, ad76fd30557d6a106c481e4606a981221ca525f7; azl3 hyperv-daemons 6.6.22.1-2 on Azure Linux 3.0 6.6.29.1-1; azl3 hyperv-daemons 6.6.29.1-1 on Azure Linux 3.0 6.6.29.1-1.
Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 440f059837418fac1695b65d3ebc6080d33be877, 4b09715f1504f1b6e8dff0e9643630610bc05141, ad76fd30557d6a106c481e4606a981221ca525f7; azl3 hyperv-daemons 6.6.22.1-2 on Azure Linux 3.0 6.6.29.1-1; azl3 hyperv-daemons 6.6.29.1-1 on Azure Linux 3.0 6.6.29.1-1 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.
