{"id":"AZL-102327","summary":"CVE-2026-90141 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nipvs: fix integer overflow in ftp helper port/address parsing\n\nip_vs_ftp_get_addrport() accumulates decimal digits into a __u16\n(hport) and into unsigned char (p[]) without checking for overflow.\nA crafted FTP PASV/EPSV response with an over-long port or address\noctet wraps the value, so the helper configures the data connection\nwith a truncated port/address.\n\nThe netfilter conntrack FTP helper had the same defect, fixed in\ncommit 2b413fc689ba (\"netfilter: nf_conntrack_ftp: avoid u16\noverflows\"). Apply the equivalent fix here: widen the port accumulator\nto u32 and reject values above 65535, and reject address octets above\n255.","modified":"2026-09-18T14:18:02.650879478Z","published":"2026-09-17T17:17:06Z","upstream":["CVE-2026-90141"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90141"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-102327.json"}}],"schema_version":"1.9.0"}
