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

  - In the Linux kernel, the following vulnerability has been resolved: can: raw: add locking for raw flags     bitfield With commit 890e5198a6e5 (can: raw: use bitfields to store flags in struct raw_sock) the     formerly separate integer values have been integrated into a single bitfield. This led to a read-modify-     write operation when changing a flag in raw_setsockopt() which now needs a locking to prevent concurrent     access. Instead of adding a lock/unlock hell in each of the flag manipulations this patch introduces a     wrapper for a new raw_setsockopt_locked() function analogue to the isotp_setsockopt[_locked]() approach in     net/can/isotp.c [mkl: use Closes tag instead of Link] (CVE-2026-68387)

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