jira VULN-42962 cve CVE-2024-35835 commit-author Zhipeng Lu <alexious@zju.edu.cn> commit 3c6d518 When `in` allocated by kvzalloc fails, arfs_create_groups will free ft->g and return an error. However, arfs_create_table, the only caller of arfs_create_groups, will hold this error and call to mlx5e_destroy_flow_table, in which the ft->g will be freed again.

jira VULN-36624 cve CVE-2024-26717 commit-author Johan Hovold <johan+linaro@kernel.org> commit 00aab7d A while back the I2C HID implementation was split in an ACPI and OF part, but the new OF driver never initialises the client pointer which is dereferenced on power-up failures.

… TD. jira VULN-42729 cve-pre CVE-2024-26659 commit-author Mathias Nyman <mathias.nyman@linux.intel.com> commit 5372c65 The last TRB of a isoc TD might not trigger an event if there was an error event for a TRB mid TD. This is seen on a NEC Corporation uPD720200 USB 3.0 Host After an error mid a multi-TRB TD the xHC should according to xhci 4.9.1 generate events for passed TRBs with IOC flag set if it proceeds to the next TD. This event is either a copy of the original error, or a "success" transfer event. If that event is missing then the driver and xHC host get out of sync as the driver is still expecting a transfer event for that first TD, while xHC host is already sending events for the next TD in the list. This leads to "Transfer event TRB DMA ptr not part of current TD" messages. As a solution we tag the isoc TDs that get error events mid TD. If an event doesn't match the first TD, then check if the tag is set, and event points to the next TD. In that case give back the fist TD and process the next TD normally Make sure TD status and transferred length stay valid in both cases with and without final TD completion event.

jira VULN-42729 cve CVE-2024-26659 commit-author Michal Pecio <michal.pecio@gmail.com> commit 7c4650d xHCI 4.9 explicitly forbids assuming that the xHC has released its ownership of a multi-TRB TD when it reports an error on one of the early TRBs. Yet the driver makes such assumption and releases the TD, allowing the remaining TRBs to be freed or overwritten by new TDs. The xHC should also report completion of the final TRB due to its IOC flag being set by us, regardless of prior errors. This event cannot be recognized if the TD has already been freed earlier, resulting in "Transfer event TRB DMA ptr not part of current TD" error message. Fix this by reusing the logic for processing isoc Transaction Errors. This also handles hosts which fail to report the final completion. Fix transfer length reporting on Babble errors. They may be caused by device malfunction, no guarantee that the buffer has been filled.

jira VULN-42554 cve CVE-2024-26603 commit-author Andrei Vagin <avagin@google.com> commit d877550 Before this change, the expected size of the user space buffer was taken from fx_sw->xstate_size. fx_sw->xstate_size can be changed from user-space, so it is possible construct a sigreturn frame where: * fx_sw->xstate_size is smaller than the size required by valid bits in fx_sw->xfeatures. * user-space unmaps parts of the sigrame fpu buffer so that not all of the buffer required by xrstor is accessible. In this case, xrstor tries to restore and accesses the unmapped area which results in a fault. But fault_in_readable succeeds because buf + fx_sw->xstate_size is within the still mapped area, so it goes back and tries xrstor again. It will spin in this loop forever. Instead, fault in the maximum size which can be touched by XRSTOR (taken from fpstate->user_size).

jira VULN-47230 cve CVE-2024-35810 commit-author Zack Rusin <zack.rusin@broadcom.com> commit 9a9e8a7 The cleanup can be dispatched while the atomic update is still active, which means that the memory acquired in the atomic update needs to not be invalidated by the cleanup. The buffer objects in vmw_plane_state instead of using the builtin map_and_cache were trying to handle the lifetime of the mapped memory themselves, leading to crashes. Use the map_and_cache instead of trying to manage the lifetime of the buffer objects held by the vmw_plane_state. Fixes kernel oops'es in IGT's kms_cursor_legacy forked-bo.

jira VULN-37041 cve CVE-2024-26846 commit-author Daniel Wagner <dwagner@suse.de> commit 70fbfc4 The module exit path has race between deleting all controllers and freeing 'left over IDs'. To prevent double free a synchronization between nvme_delete_ctrl and ida_destroy has been added by the initial commit. There is some logic around trying to prevent from hanging forever in wait_for_completion, though it does not handling all cases. E.g. blktests is able to reproduce the situation where the module unload hangs forever. If we completely rely on the cleanup code executed from the nvme_delete_ctrl path, all IDs will be freed eventually. This makes calling ida_destroy unnecessary. We only have to ensure that all nvme_delete_ctrl code has been executed before we leave nvme_fc_exit_module. This is done by flushing the nvme_delete_wq workqueue. While at it, remove the unused nvme_fc_wq workqueue too.
