{"apiVersion":"1.0","identifier":"CVE-2026-72107","description":"In the Linux kernel, the following vulnerability has been resolved: dm era: fix out-of-bounds memory access for non-zero start sector dm-era tracks writes in target-relative blocks, but era_map() calculates the writeset block before applying the target offset. Tables with a non-zero start sector can therefore pass an absolute mapped-device block to metadata_current_marked(). If the absolute block is beyond the current writeset size, writeset_marked() tests past the end of the in-core bitset. KASAN reports this as a vmalloc-out-of-bounds access. Apply the target offset before calculating the era block so writeset lookups use the target-relative block number.","publishedAt":"2026-08-15T06:21:24","lastModifiedAt":"2026-08-17T06:18:09","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72107","cvssScore":8.8,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00632,"riskScore":0.93,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72107","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72107","en":"https://www.redsauce.net/en/cves/CVE-2026-72107","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72107","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72107","de":"https://www.redsauce.net/de/cves/CVE-2026-72107","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72107","el":"https://www.redsauce.net/el/cves/CVE-2026-72107"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72107"}}
