Google: sys-kernel/lakitu-kernel-5_10: security update to 17033.0.0

medium Tenable Cloud Security Plugin ID 452158

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: PCI: pciehp: Fix infinite loop in IRQ
handler upon power fault The Power Fault Detected bit in the Slot Status register differs from all other
hotplug events in that it is sticky: It can only be cleared after turning off slot power. Per PCIe r5.0,
sec. 6.7.1.8: If a power controller detects a main power fault on the hot-plug slot, it must automatically
set its internal main power fault latch [...]. The main power fault latch is cleared when software turns
off power to the hot-plug slot. The stickiness used to cause interrupt storms and infinite loops which
were fixed in 2009 by commits 5651c48cfafe ("PCI pciehp: fix power fault interrupt storm problem") and
99f0169c17f3 ("PCI: pciehp: enable software notification on empty slots"). Unfortunately in 2020 the
infinite loop issue was inadvertently reintroduced by commit 8edf5332c393 ("PCI: pciehp: Fix MSI interrupt
race"): The hardirq handler pciehp_isr() clears the PFD bit until pciehp's power_fault_detected flag is
set. That happens in the IRQ thread pciehp_ist(), which never learns of the event because the hardirq
handler is stuck in an infinite loop. Fix by setting the power_fault_detected flag already in the hardirq
handler. (CVE-2021-47617)

Solution

Update the sys-kernel/lakitu-kernel-5_10 library and its related packages to version 17033.0.0 or later.
