{"apiVersion":"1.0","identifier":"CVE-2026-99098","description":"In the Linux kernel, the following vulnerability has been resolved: dm-integrity: fix buffer overflow in inline mode with large tag size In inline mode, dm_integrity_check and dm_integrity_inline_recheck compute the checksum of each block into an on-stack buffer of HASH_MAX_DIGESTSIZE bytes. integrity_sector_checksum pads its result with zeroes up to the tag size, so if the tag size is larger than HASH_MAX_DIGESTSIZE, the padding runs past the end of the buffer. With CONFIG_STACKPROTECTOR the kernel panics in dm_integrity_check on the first read. Enlarge both buffers to hold MAX_TAG_SIZE bytes, as commit b93b6643e9b5 (-dm integrity: fix a crash with unusually large tag size-) did for integrity_metadata. Note that this is not a security bug because the buffer overflow can only be triggered by root.","publishedAt":"2026-10-26T15:16:48","lastModifiedAt":"2026-10-26T15:16:48","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-99098","cvssScore":null,"cvssVector":null,"epssProbability":0.00181,"riskScore":null,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-99098","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-99098","en":"https://www.redsauce.net/en/cves/CVE-2026-99098","fr":"https://www.redsauce.net/fr/cves/CVE-2026-99098","pt":"https://www.redsauce.net/pt/cves/CVE-2026-99098","de":"https://www.redsauce.net/de/cves/CVE-2026-99098","sk":"https://www.redsauce.net/sk/cves/CVE-2026-99098","el":"https://www.redsauce.net/el/cves/CVE-2026-99098"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-99098"}}
