https://notcve.org/view.php?id=CVE-2024-43892
In the Linux kernel, the following vulnerability has been resolved: memcg: protect concurrent access to mem_cgroup_idr Commit 73f576c04b94 ("mm: memcontrol: fix cgroup creation failure after many small jobs") decoupled the memcg IDs from the CSS ID space to fix the cgroup creation failures. It introduced IDR to maintain the memcg ID space. The IDR depends on external synchronization mechanisms for modifications. For the mem_cgroup_idr, the idr_alloc() and idr_replace() happen within css callback and thus are protected through cgroup_mutex from concurrent modifications. However idr_remove() for mem_cgroup_idr was not protected against concurrency and can be run concurrently for different memcgs when they hit their refcnt to zero. • https://git.kernel.org/stable/c/73f576c04b9410ed19660f74f97521bee6e1c546 https://git.kernel.org/stable/c/8627c7750a66a46d56d3564e1e881aa53764497c https://git.kernel.org/stable/c/db70cd18d3da727a3a59694de428a9e41c620de7 https://git.kernel.org/stable/c/912736a0435ef40e6a4ae78197ccb5553cb80b05 https://git.kernel.org/stable/c/e6cc9ff2ac0b5df9f25eb790934c3104f6710278 https://git.kernel.org/stable/c/56fd70f4aa8b82199dbe7e99366b1fd7a04d86fb https://git.kernel.org/stable/c/37a060b64ae83b76600d187d76591ce488ab836b https://git.kernel.org/stable/c/51c0b1bb7541f8893ec1accba59eb0436 •

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Add null check in resource_log_pipe_topology_update [WHY] When switching from "Extend" to "Second Display Only" we sometimes call resource_get_otg_master_for_stream on a stream for the eDP, which is disconnected. This leads to a null pointer dereference.

https://notcve.org/view.php?id=CVE-2024-43883
In the Linux kernel, the following vulnerability has been resolved: usb: vhci-hcd: Do not drop references before new references are gained At a few places the driver carries stale pointers to references that can still be used. Make sure that does not happen. This strictly speaking closes ZDI-CAN-22273, though there may be similar races in the driver. • https://git.kernel.org/stable/c/5a3c473b28ae1c1f7c4dc129e30cb19ae6e96f89 https://git.kernel.org/stable/c/9c3746ce8d8fcb3a2405644fc0eec7fc5312de80 https://git.kernel.org/stable/c/4dacdb9720aaab10b6be121eae55820174d97174 https://git.kernel.org/stable/c/e8c1e606dab8c56cf074b43b98d0805de7322ba2 https://git.kernel.org/stable/c/585e6bc7d0a9bf73a8be3d3fb34e86b90cc61a14 https://git.kernel.org/stable/c/128e82e41cf7d74a562726c1587d9d2ede1a0a37 https://git.kernel.org/stable/c/c3d0857b7fc2c49f68f89128a5440176089a8f54 https://git.kernel.org/stable/c/afdcfd3d6fcdeca2735ca8d994c5f2d24 •

https://notcve.org/view.php?id=CVE-2022-48938
In the Linux kernel, the following vulnerability has been resolved: CDC-NCM: avoid overflow in sanity checking A broken device may give an extreme offset like 0xFFF0 and a reasonable length for a fragment. In the sanity check as formulated now, this will create an integer overflow, defeating the sanity check. Both offset and offset + len need to be checked in such a manner that no overflow can occur. And those quantities should be unsigned. • https://git.kernel.org/stable/c/69560efa001397ebb8dc1c3e6a3ce00302bb9f7f https://git.kernel.org/stable/c/49909c9f8458cacb5b241106cba65aba5a6d8f4c https://git.kernel.org/stable/c/7b737e47b87589031f0d4657f6d7b0b770474925 https://git.kernel.org/stable/c/8d2b1a1ec9f559d30b724877da4ce592edc41fdc •
