critical Nessus Plugin ID 333074

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- smb/client: Fix error code in smb2_aead_req_alloc() The *num_sgs variable is a u32 so ERR_PTR(*num_sgs) doesn't work. We would have to do something similar to the previous line where it's cast to int and then long. However, it's simpler to store the return in an int ret variable. This bug would eventually result in a crash when dereference the invalid error pointer. (CVE-2026-64598)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
