In the Linux kernel, the following vulnerability has been resolved: net/smc: carry oversized SMC-Rv2 LLC messages in the queue entry smc_llc_rmt_delete_rkey() and smc_llc_save_add_link_rkeys() read the part of a v2 message that does not fit into the 44-byte union smc_llc_msg, and both bound themselves by the size of the buffer it landed in, not by what arrived. On a link with a shared v2 receive buffer a 44-byte DELETE_RKEY_V2 declaring 255 rkeys reaches rkey[9..254] in whatever an earlier message left in lgr->wr_rx_buf_v2, and passes each of them to smc_rtoken_delete(). One of those 255 matched a registered rtoken and deleted it. An ADD_LINK on such a link installs up to 255 rtokens from the same bytes. Copy the tail into the queue entry, so its length is the length of the message that arrived, and declare the rkeys that fit inline as a member of the union instead of reaching them through a cast. The same DELETE_RKEY_V2 now processes the 9 rkeys it carries. The copy is limited to the longest tail the two functions can read, so the peer does not pick the size of the entry. The bound the previous patch placed on links without a shared v2 receive buffer is no longer needed.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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

  - net/smc: carry oversized SMC-Rv2 LLC messages in the queue entry smc_llc_rmt_delete_rkey() and     smc_llc_save_add_link_rkeys() read the part of a v2 message that does not fit into the 44-byte union     smc_llc_msg, and both bound themselves by the size of the buffer it landed in, not by what arrived. On a     link with a shared v2 receive buffer a 44-byte DELETE_RKEY_V2 declaring 255 rkeys reaches rkey[9..254] in     whatever an earlier message left in lgr->wr_rx_buf_v2, and passes each of them to smc_rtoken_delete(). One     of those 255 matched a registered rtoken and deleted it. An ADD_LINK on such a link installs up to 255     rtokens from the same bytes. Copy the tail into the queue entry, so its length is the length of the     message that arrived, and declare the rkeys that fit inline as a member of the union instead of reaching     them through a cast. The same DELETE_RKEY_V2 now processes the 9 rkeys it carries. The copy is limited to     the longest tail the two functions can read, so the peer does not pick the size of the entry. The bound     the previous patch placed on links without a shared v2 receive buffer is no longer needed.
    (CVE-2026-80985)

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