{"id":"RLSA-2026:39575","summary":"Important: cifs-utils security, bug fix, and enhancement update","details":"The SMB/CIFS protocol is a standard file sharing protocol widely deployed on Microsoft Windows machines. The cifs-utils packages contain tools for mounting shares on Linux using the SMB/CIFS protocol. The tools in this package work in conjunction with support in the kernel to allow one to mount a SMB/CIFS share onto a client and use it as if it were a standard Linux file system.\n\nSecurity Fix(es):\n\n* cifs-utils: local privilege escalation via forged cifs.spnego key description in cifs.upcall (CVE-2026-12505)\n\nBug Fix(es) and Enhancement(s):\n\n* add sssd method for mapping SID to UID/GID in man page of mount.cifs [rhel-8.10.z] (JIRA:Rocky Linux-41059)\n\n* Update the mount.cifs man page to match the 3*echo_interval reconnection timeout (JIRA:Rocky Linux-80397)\n\n* cifs-utils: regression with kerberos mount [rhel-8.10.z] (JIRA:Rocky Linux-192933)\n\nFor more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.","modified":"2026-07-23T12:30:06.604425095Z","published":"2026-07-23T12:00:46.971123Z","upstream":["CVE-2026-12505"],"references":[{"type":"ADVISORY","url":"https://errata.rockylinux.org/RLSA-2026:39575"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2489805"}],"affected":[{"package":{"name":"cifs-utils","ecosystem":"Rocky Linux:8","purl":"pkg:rpm/rocky-linux/cifs-utils?distro=rocky-linux-8&epoch=0"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0:7.0-5.el8_10"}],"database_specific":{"yum_repository":"BaseOS"}}],"database_specific":{"source":"https://storage.googleapis.com/resf-osv-data/RLSA-2026:39575.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}],"credits":[{"name":"Rocky Enterprise Software Foundation"},{"name":"Red Hat"}]}
