Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
