CVE-2026-64386CVE-2026-64386
linux / linux_kernel
Description
In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix query_info() replay double-free
A response-bearing attempt can return a replayable error and free its
response buffer. If SMB2_query_info_init() fails before the next send,
cleanup retains the previous buffer type and frees that response again.
Reset response bookkeeping before each attempt to prevent the stale free.
