medium Tenable Self-Hosted Container Security Plugin ID 469434

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: nvmet-tcp: fix page fragment cache
leak in error path In nvmet_tcp_alloc_queue(), when a connection is closed during the allocation process
(e.g., nvmet_tcp_set_queue_sock() returns -ENOTCONN), the error handling jumps to out_destroy_sq and then
to out_ida_remove without draining the page fragment cache. Although nvmet_tcp_free_cmd() is called in
some error paths to release individual page fragments, the underlying page cache reference held by
queue->pf_cache is never released. The first allocation using pf_cache is the call to
nvmet_tcp_alloc_cmd() for queue->connect, which happens after ida_alloc() returns successfully. This
results in a page leak each time a connection fails during allocation, which could lead to memory
exhaustion over time if connections are repeatedly opened and closed. Fix this by calling
page_frag_cache_drain() before freeing the queue structure in the out_ida_remove label. (CVE-2026-74386)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.448.8 or later.
