CVE-2026-64382CVE-2026-64382
linux / linux_kernel
Description
In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix double-free in SMB2_open() replay
A response-bearing attempt can return a replayable error and free its
response buffer. If SMB2_open_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.
