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

  - net: stmmac: fix oops when split header is enabled For GMAC4, when split header is enabled, in some rare     cases, the hardware does not fill buf2 of the first descriptor with payload. Thus we cannot assume buf2 is     always fully filled if it is not the last descriptor. Otherwise, the length of buf2 of the second     descriptor will be calculated wrong and cause an oops: Unable to handle kernel paging request at virtual     address ffff00019246bfc0 ... x2 : 0000000000000040 x1 : ffff00019246bfc0 x0 : ffff00009246c000 Call trace:

To fix this, the PL bit-field in RDES3 register     is used for all descriptors, whether it is the last descriptor or not. (CVE-2026-45940)
