[PATCH OLK-6.6] VMCI: Fix use-after-free when removing resource in vmci_resource_remove()
by Zhang Kunbo 26 Sep '24

26 Sep '24

From: David Fernandez Gonzalez <david.fernandez.gonzalez(a)oracle.com> stable inclusion from stable-v6.6.51 commit 39e7e593418ccdbd151f2925fa6be1a616d16c96 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IARY1L CVE: CVE-2024-46738 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 48b9a8dabcc3cf5f961b2ebcd8933bf9204babb7 upstream. When removing a resource from vmci_resource_table in vmci_resource_remove(), the search is performed using the resource handle by comparing context and resource fields. It is possible though to create two resources with different types but same handle (same context and resource fields). When trying to remove one of the resources, vmci_resource_remove() may not remove the intended one, but the object will still be freed as in the case of the datagram type in vmci_datagram_destroy_handle(). vmci_resource_table will still hold a pointer to this freed resource leading to a use-after-free vulnerability.

[PATCH OLK-6.6] char: xillybus: Check USB endpoints when probing device
by Ye Bin 26 Sep '24

26 Sep '24

From: Eli Billauer <eli.billauer(a)gmail.com> stable inclusion from stable-v6.6.48 commit 5cff754692ad45d5086b75fef8cc3a99c30a1005 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAQOJN CVE: CVE-2024-45011 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 2374bf7558de915edc6ec8cb10ec3291dfab9594 upstream. Ensure, as the driver probes the device, that all endpoints that the driver may attempt to access exist and are of the correct type. All XillyUSB devices must have a Bulk IN and Bulk OUT endpoint at address 1. This is verified in xillyusb_setup_base_eps(). On top of that, a XillyUSB device may have additional Bulk OUT endpoints. The information about these endpoints' addresses is deduced from a data structure (the IDT) that the driver fetches from the device while probing it. These endpoints are checked in setup_channels(). A XillyUSB device never has more than one IN endpoint, as all data towards the host is multiplexed in this single Bulk IN endpoint. This is why setup_channels() only checks OUT endpoints.

[PATCH openEuler-1.0-LTS] VMCI: Fix use-after-free when removing resource in vmci_resource_remove()
by Zhang Kunbo 26 Sep '24

26 Sep '24

From: David Fernandez Gonzalez <david.fernandez.gonzalez(a)oracle.com> stable inclusion from stable-v4.19.322 commit f6365931bf7c07b2b397dbb06a4f6573cc9fae73 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IARY1L CVE: CVE-2024-46738 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 48b9a8dabcc3cf5f961b2ebcd8933bf9204babb7 upstream. When removing a resource from vmci_resource_table in vmci_resource_remove(), the search is performed using the resource handle by comparing context and resource fields. It is possible though to create two resources with different types but same handle (same context and resource fields). When trying to remove one of the resources, vmci_resource_remove() may not remove the intended one, but the object will still be freed as in the case of the datagram type in vmci_datagram_destroy_handle(). vmci_resource_table will still hold a pointer to this freed resource leading to a use-after-free vulnerability.
