CVE-2022-49443

CVE-2022-49443 relates to a data race in Linux kernel epoll during epoll_wait, caused by lockless access to ep->rdllist via ep_events_available and list handling. The issue manifests as a KCSAN-detected race between ep_start_scan/ep_send_events and do_epoll_wait, potentially affecting availabi...

CVE-2022-49443 list: fix a data-race around ep->rdllist

In the Linux kernel, the following vulnerability has been resolved: list: fix a data-race around ep-rdllist eppoll first calls epeventsavailable with no lock held and checks if ep-rdllist is empty by listemptycareful, which reads rdllist-prev. Thus all accesses to it need some protection to avoid...

CVE-2022-49434

The CVE-2022-49434 issue is in the Linux kernel where pci_dev_lock() historically acquired the config space access lock before the device lock, risking AB/BA deadlocks with sriov_numvfs_store() that already takes the device lock first. The fix is to reverse the order in pci_dev_lock() so it acqui...
