The AlmaLinux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1779434490 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: configfs: fix a race in     configfs_{,un}register_subsystem() When configfs_register_subsystem() or configfs_unregister_subsystem()     is executing link_group() or unlink_group(), it is possible that two processes add or delete list     concurrently. Some unfortunate interleavings of them can cause kernel panic. One of cases is: A --> B -->     C --> D A <-- B <-- C <-- D delete list_head *B | delete list_head *C
    --------------------------------|----------------------------------- configfs_unregister_subsystem |     configfs_unregister_subsystem unlink_group | unlink_group unlink_obj | unlink_obj list_del_init |     list_del_init __list_del_entry | __list_del_entry __list_del | __list_del // next == C | next->prev = prev     | | next->prev = prev prev->next = next | | // prev == B | prev->next = next Fix this by adding mutex when     calling link_group() or unlink_group(), but parent configfs_subsystem is NULL when config_item is root. So     I create a mutex configfs_subsystem_mutex. (CVE-2022-48931)

  - In the Linux kernel, the following vulnerability has been resolved: list: fix a data-race around     ep->rdllist ep_poll() first calls ep_events_available() with no lock held and checks if ep->rdllist is     empty by list_empty_careful(), which reads rdllist->prev. Thus all accesses to it need some protection to     avoid store/load-tearing. Note INIT_LIST_HEAD_RCU() already has the annotation for both prev and next.
    Commit bf3b9f6372c4 (epoll: Add busy poll support to epoll with socket fds.) added the first lockless     ep_events_available(), and commit c5a282e9635e (fs/epoll: reduce the scope of wq lock in epoll_wait())     made some ep_events_available() calls lockless and added single call under a lock, finally commit     e59d3c64cba6 (epoll: eliminate unnecessary lock for zero timeout) made the last ep_events_available()     lockless.
