- 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.
Security Fix(es):
- cifs-utils: local privilege escalation via forged cifs.spnego key description in cifs.upcall (CVE-2026-12505)
Bug Fix(es) and Enhancement(s):
add sssd method for mapping SID to UID/GID in man page of mount.cifs [rhel-8.10.z] (JIRA:Rocky Linux-41059)
Update the mount.cifs man page to match the 3*echo_interval reconnection timeout (JIRA:Rocky Linux-80397)
cifs-utils: regression with kerberos mount [rhel-8.10.z] (JIRA:Rocky Linux-192933)
