high Tenable Self-Hosted Container Security Plugin ID 468370

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: printk: Fix possible console use-
after-free When emitting a record via legacy printing, it is possible that a handover to another legacy
printing context occurs. When a context has performed a handover, the console SRCU read lock is released
and the pointer to the console struct might now be invalid. Therefore, after calling
nbcon_legacy_emit_next_record() or console_emit_next_record(), it is necessary to check if a handover
occurred _before_ further @con usage. Sashiko pointed out that console_flush_one_record() was not doing
this. In console_flush_one_record(), after emitting a record, move the further usage of @con after the
handover check. (CVE-2026-93134)

Solution

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