high Tenable Cloud Security Plugin ID 474976

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: nvme-tcp: fix host memory disclosure
 on R2T for a read command nvme_tcp_handle_r2t() does not check the direction of the request the R2T refers
 to. A malicious controller can send an R2T for a READ and the host will answer it:
 nvme_tcp_setup_h2c_data_pdu() builds the H2CData header and nvme_tcp_try_send_data() sends the request's
 data buffer. That buffer is the READ destination, so its contents go to the controller. The command then
 completes normally and nothing is logged. Against a test controller that answers every READ with an R2T, a
 4096 byte buffered read returned all 4096 bytes, split over two R2Ts. The pages contained stale kernel
 data, including an array of struct page pointers. Reject an R2T for a request that is not a write.
 (CVE-2026-89481)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.700.7 or later.
