CVE-2026-43147

In the Linux kernel, the following vulnerability has been resolved: Revert "PCI/IOV: Add PCI rescan-remove locking when enabling/disabling SR-IOV" This reverts commit 05703271c3cd "PCI/IOV: Add PCI rescan-remove locking when enabling/disabling SR-IOV", which causes a deadlock by recursively takin...

CVE-2026-43147

CVE-2026-43147 concerns a deadlock in the Linux kernel SR-IOV removal path. The issue arises when sriov_del_vfs() is invoked during pci_stop_and_remove_bus_device(), causing a recursive lock acquisition on pci_rescan_remove_lock and leading to system unresponsiveness. The public description confi...

CVE-2026-43143

In the Linux kernel, CVE-2026-43143 fixes a concurrency issue in the multi-function device (mfd) core: access/modification of the mfd_of_node_list was not mutex-protected, risking unsafe list manipulation and potential crashes. The fix adds a mutex to guard this list, reducing crash likelihood. P...
