Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified) openSUSE Tumbleweed versions prior to kernel-devel-7.0.11-1.1
Description A duplicate resource teardown occurs in the PCI endpoint pci-epf-ntb component. The function epf ntb epc destroy() performs teardown actions that the caller is already expected to execute, which can lead to a system oops (a kernel panic or crash) when .allow link fails or when .drop link is performed.
Recommendations Update the Linux kernel to a version where the epf ntb epc destroy() helper has been removed. Update openSUSE Tumbleweed to the kernel-devel-7.0.11-1.1 package.
