If function 0 is removed before sibling function,\nlink->downstream would point to free'd memory after.\n\nAfter above change, we freed the ASPM parent link state upon any function\nremoval on the bus pertaining to a given link.\n\nThat is too early. If the link is to a PCIe switch with MFD on the upstream\nport, then removing functions other than 0 first would free a link which\nstill remains parent_link to the remaining downstream ports.\n\nThe resulting GPFs are especially frequent during hot-unplug, because\npciehp removes devices on the link bus in reverse order.\n\nOn that switch, function 0 is the virtual P2P bridge to the internal bus.\nFree exactly when function 0 is removed -- before the parent link is\nobsolete, but after all subordinate links are gone.\n\n[kwilczynski: commit log]\n\n## Affected\n\n- `linux_kernel >= 5.4.251, < 5.5`\n- `linux_kernel >= 5.10.188, < 5.11`\n- `linux_kernel >= 5.15.121, < 5.16`\n- `linux_kernel >= 6.1.39, < 6.2`\n- `linux_kernel >= 6.3.13, < 6.4`\n- `linux_kernel >= 6.4.4, < 6.15`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `linux_kernel 6.15`","depth":"twilight","depthScore":43,"depthScoreParts":{"impact":42.9,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
