In the Linux kernel, the following vulnerability has been resolved:
cifs: Fix oops due to uninitialised variable
Fix smb3_init_transform_rq() to initialise buffer to NULL before calling
netfs_alloc_folioq_buffer() as netfs assumes it can append to the buffer it
is given. Setting it to NULL means it should start a fresh buffer, but the
value is currently undefined.

CVE-2025-38737 [MEDIUM] CWE-908 kernel: cifs: Fix oops due to uninitialised variable
kernel: cifs: Fix oops due to uninitialised variable
In the Linux kernel, the following vulnerability has been resolved:
cifs: Fix oops due to uninitialised variable
Fix smb3_init_transform_rq() to initialise buffer to NULL before calling
netfs_alloc_folioq_buffer() as netfs assumes it can append to the buffer it
is given. Setting it to NULL means it should start a fresh buffer, but the
value is currently undefined.
Statement: An unprivileged local user with access to an SMB3 share with encryption enabled can trigger this vulnerability through normal file operations, which due to the encryption will cause transform requests (i.e. encryption/decryption operations).
