medium Tenable Cloud Security Plugin ID 469180

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: kernel/fork: clear PF_BLOCK_TS in
 copy_process() PF_BLOCK_TS is only set in blk_time_get_ns() when current->plug is non-NULL, and
 blk_finish_plug() clears it via __blk_flush_plug() before NULLing the plug pointer. copy_process() breaks
 the invariant by inheriting PF_BLOCK_TS from the parent while resetting the child's plug to NULL. Clear
 PF_BLOCK_TS alongside that assignment so callers can rely on "PF_BLOCK_TS set implies current->plug !=
 NULL" and dereference current->plug unguarded. (CVE-2026-64253)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.532.96 or later.
