CVE-2026-58731

Status: AnalyzedMedium (6.2)—

In multiple functions of physmem_extmem_linux.c, there is a possible out-of-bounds read due to uninitialized data. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
