CVE-2026-88365

Summary

The flaw is an integer overflow vulnerability in the mp3dec_skip_id3v1() function when parsing the APEv2 tag-size field, which can lead to arbitrary code execution. This matters because attackers can exploit it to execute malicious code, leading to severe system compromise.

Exploitability

Exploiting this vulnerability is relatively easy given the critical severity and the presence of a public exploit. The attacker needs to craft a specially crafted MP3 file containing an APEv2 tag with an oversized size field.

Blast radius

If exploited, this vulnerability could result in complete system compromise, allowing attackers to execute arbitrary code with the privileges of the user running the vulnerable application.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Disable the affected mp3dec functionality or upgrade to the version containing the fix, such as 'Upgrade to the version containing the fix for CVE-2026-88365 or later'.
