Описание
In the Linux kernel, the following vulnerability has been resolved:
powerpc/eeh: avoid possible crash when edev->pdev changes
If a PCI device is removed during eeh_pe_report_edev(), edev->pdev
will change and can cause a crash, hold the PCI rescan/remove lock
while taking a copy of edev->pdev->bus.
A flaw was found in the Linux kernel's PowerPC Enhanced Error Handling (EEH) subsystem. If a Peripheral Component Interconnect (PCI) device is removed while error reporting is in progress, the kernel fails to hold the proper lock when copying device references. A local user could exploit this race condition during device removal to trigger a system crash, resulting in a Denial of Service (DoS).
Отчет
Following issue marked as moderate with "not affected or will not fix" for Red Hat Enterprise Linux, as it is not vulnerable to this CVE. This is because the CVE does not impact the versions or configurations of the Linux kernel used in Red Hat's distributions.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
