Parsing a symlink entry in an untrusted RPM package whose declared RPMTAG_LONGFILESIZES value is 0xFFFFFFFFFFFFFFFF causes an integer overflow in iterReadArchiveNext() that shrinks a buffer allocation to one byte, after which the payload's independently-controlled cpio filesize field is used to write attacker-controlled data past the end of that allocation. This is reachable via rpm2cpio, rpm2archive, and rpm -qlvp on an  untrusted package.","epss":{"date":"2026-11-05","percentile":0.01797,"score":0.00119},"exploits":[],"kev":null,"metrics":[{"score":7.1,"severity":"high","source":"CNA: redhat","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H","version":"3.1"}],"modifiedAt":1793931240481,"publishedAt":1790679726457,"references":[{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-95520"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2537809"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","text":"To reduce exposure, avoid processing or extracting RPM packages from untrusted sources.
