{"id":"AZL-100184","summary":"CVE-2026-89608 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\necryptfs: pass packet set buffer size to parser\n\necryptfs_parse_packet_set() receives a pointer into the file header, but\nit calculates the remaining packet buffer size from PAGE_SIZE - 8.  For\nversion 1 headers the packet set starts later in the header, so this can\noverstate the available buffer.\n\nPass the actual packet set buffer length from the caller and calculate\nper-packet limits from the remaining bytes in that buffer.  Recompute the\nremaining length after consuming a tag 3 packet before parsing the\nfollowing tag 11 packet.","modified":"2026-09-13T06:06:36Z","published":"2026-09-11T20:19:45Z","upstream":["CVE-2026-89608"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89608"}],"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-100184.json"}}],"schema_version":"1.9.0"}
