medium Tenable Cloud Security Plugin ID 474984

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: serial: 8250: fix possible ISR soft
lockup There are rare cases in which the host gets stuck in the ISR because it is flooded with messages
during the startup phase. The reason for the soft lockup in the ISR is the missing FIFO error IRQ (FIFOE)
handling. Not handling it and reporting IRQ_HANDLED triggers the IRQ immediately again. Fix this by adding
a check for the FIFOE status and clearing the FIFO if no data is ready (DR). This behavior was observed on
an AM62L device which uses the OMAP 8250 driver. Fix it for all 8250 drivers, since the OMAP driver's
special IRQ setup handling may trigger this behavior more frequently, but it is not ensured that other
8250 drivers aren't affected. (CVE-2026-97481)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.739.5 or later.
