fkie_cve-2025-22041

In the Linux kernel, the following vulnerability has been resolved:

ksmbd: fix use-after-free in ksmbd_sessions_deregister()

In multichannel mode, UAF issue can occur in session_deregister when the second channel sets up a session through the connection of the first channel. session that is freed through the global session table can be accessed again through ->sessions of connection.

OESA-2025-1463 — kernel security update

Affected: openEuler:24.03-LTS: kernel

The Linux Kernel, the operating system core itself. Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

PCI/ASPM: Fix link state exit during switch upstream function removal

Before 456d8aa37d0f ("PCI/ASPM: Disable ASPM on MFD function removal to avoid use-after-free"), we would free the ASPM link only after the last function on the bus pertaining to the given link was removed.

That was too late. If function 0 is removed before sibling function, link->downstream would point to free'd memory after.

After above change, we freed the ASPM parent link state upon any function removal on the bus pertaining to a given link.

That is too early. If the link is to a PCIe switch with MFD on the upstream port, then removing functions other than 0 first would free a link which still remains parent_link to the remaining downstream ports.

The resulting GPFs are especially frequent during hot-unplug, because pciehp removes devices on the link bus in reverse order.

On that switch, function 0 is the virtual P2P bridge to the internal bus. Free exactly when function 0 is removed -- before the parent link is obsolete, but after all subordinate links are gone.
