CVE-2025-37937: objtool, media: dib8000: Prevent divide-by-zero in dib8000_set_dds()

MediumCVSS 5.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 22/100)

  • 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: 0.24% (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 536f7f3595ef8187cfa9ea50d7d24fcf4e84e166, 6cfe46036b163e5a0f07c6b705b518148e1a8b2f, 75b42dfe87657ede3da3f279bd6b1b16d69af954.

Low priority for now. Upgrade to Linux Linux 536f7f3595ef8187cfa9ea50d7d24fcf4e84e166, 6cfe46036b163e5a0f07c6b705b518148e1a8b2f, 75b42dfe87657ede3da3f279bd6b1b16d69af954 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: objtool, media: dib8000: Prevent divide-by-zero in dib8000_set_dds() If dib8000_set_dds()'s call to dib8000_read32() returns zero, the result is a divide-by-zero. Prevent that from happening. Fixes the following warning with an UBSAN kernel: drivers/media/dvb-frontends/dib8000.o: warning: objtool: dib8000_tune() falls through to next function dib8096p_cfg_DibRx()
