Technical description

In the Linux kernel, the following vulnerability has been resolved:

smb: client: fix oops due to uninitialised var in smb2_unlink()

If SMB2_open_init() or SMB2_close_init() fails (e.g. reconnect), the

iovs set @rqst will be left uninitialised, hence calling

SMB2_open_free(), SMB2_close_free() or smb2_set_related() on them will

oops.

Fix this by initialising @close_iov and @open_iov before setting them

in @rqst.

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.
