high Tenable Self-Hosted Container Security Plugin ID 462175

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: sh: push-switch: Reorder cleanup
 operations to avoid use-after-free bug The original code puts flush_work() before timer_shutdown_sync() in
 switch_drv_remove(). Although we use flush_work() to stop the worker, it could be rescheduled in
 switch_timer(). As a result, a use-after-free bug can occur. The details are shown below: (cpu 0) | (cpu
 1) switch_drv_remove() | flush_work() | ... | switch_timer // timer | schedule_work(&psw->work)
 timer_shutdown_sync() | ... | switch_work_handler // worker kfree(psw) // free | | psw->state = 0 // use
 This patch puts timer_shutdown_sync() before flush_work() to mitigate the bugs. As a result, the worker
 and timer will be stopped safely before the deallocate operations. (CVE-2023-52629)

Solution

Update the linux library and its related packages to version 6.5.6-1 or later.
