{"id":"AZL-100782","summary":"CVE-2026-89466 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\npower: supply: qcom_battmgr: terminate the strings from firmware\n\nThe qcom_battmgr_sc8280xp_strcpy() takes a Pascal-style string when the\nfirmware sends one. Otherwise it copies all BATTMGR_STRING_LEN bytes and\nleaves the destination without a terminator.\n\nThose destinations are model_number, serial_number and oem_info, each\nBATTMGR_STRING_LEN and declared next to each other. They go out to user\nspace as val-\u003estrval, which power_supply_format_property() prints with\n\"%s\", so a firmware string that fills the whole field makes that read run\ninto the following members.\n\nUse strscpy() so the copy always terminates, the way the SM8350 path\nalready does for the same field.","modified":"2026-09-13T06:06:36Z","published":"2026-09-11T20:19:27Z","upstream":["CVE-2026-89466"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89466"}],"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-100782.json"}}],"schema_version":"1.9.0"}
