CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-46740 – binder: fix UAF caused by offsets overwrite
https://notcve.org/view.php?id=CVE-2024-46740
In the Linux kernel, the following vulnerability has been resolved: binder: fix UAF caused by offsets overwrite Binder objects are processed and copied individually into the target buffer during transactions. Any raw data in-between these objects is copied as well. However, this raw data copy lacks an out-of-bounds check. If the raw data exceeds the data section size then the copy overwrites the offsets section. This eventually triggers an error that attempts to unwind the processed objects. • https://git.kernel.org/stable/c/c056a6ba35e00ae943e377eb09abd77a6915b31a https://git.kernel.org/stable/c/23e9d815fad84c1bee3742a8de4bd39510435362 https://git.kernel.org/stable/c/7a9ad4aceb0226b391c9d3b8e4ac2e7d438b6bde https://git.kernel.org/stable/c/6d98eb95b450a75adb4516a1d33652dc78d2b20c https://git.kernel.org/stable/c/66e12f5b3a9733f941893a00753b10498724607d https://git.kernel.org/stable/c/5a32bfd23022ffa7e152f273fa3fa29befb7d929 https://git.kernel.org/stable/c/3a8154bb4ab4a01390a3abf1e6afac296e037da4 https://git.kernel.org/stable/c/eef79854a04feac5b861f94d7b19cbbe7 •

In the Linux kernel, the following vulnerability has been resolved: uio_hv_generic: Fix kernel NULL pointer dereference in hv_uio_rescind For primary VM Bus channels, primary_channel pointer is always NULL. This pointer is valid only for the secondary channels. Also, rescind callback is meant for primary channels only.

CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-46738 – VMCI: Fix use-after-free when removing resource in vmci_resource_remove()
https://notcve.org/view.php?id=CVE-2024-46738
In the Linux kernel, the following vulnerability has been resolved: VMCI: Fix use-after-free when removing resource in vmci_resource_remove() 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.
