CVE-2026-99280 Nov 7, 2026 Source: Vendor
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: drain session procfs readers before dropping table references
Session registration failure and connection cleanup can drop the table
reference while the per-session procfs entry is still accessible. If a
reader holds the last remaining reference, its final put calls
proc_remove() from its own callback and waits for that callback to
finish.
Remove the procfs entry before dropping the table reference in the
registration
