https://notcve.org/view.php?id=CVE-2024-47698
In the Linux kernel, the following vulnerability has been resolved: drivers: media: dvb-frontends/rtl2832: fix an out-of-bounds write error Ensure index in rtl2832_pid_filter does not exceed 31 to prevent out-of-bounds access. dev->filters is a 32-bit value, so set_bit and clear_bit functions should only operate on indices from 0 to 31. If index is 32, it will attempt to access a non-existent 33rd bit, leading to out-of-bounds access. Change the boundary check from index > 32 to index >= 32 to resolve this issue.

https://notcve.org/view.php?id=CVE-2024-47696
In the Linux kernel, the following vulnerability has been resolved: RDMA/iwcm: Fix WARNING:at_kernel/workqueue.c:#check_flush_dependency In the commit aee2424246f9 ("RDMA/iwcm: Fix a use-after-free related to destroying CM IDs"), the function flush_workqueue is invoked to flush the work queue iwcm_wq. But at that time, the work queue iwcm_wq was created via the function alloc_ordered_workqueue without the flag WQ_MEM_RECLAIM. Because the current process is trying to flush the whole iwcm_wq, if iwcm_wq doesn't have the flag WQ_MEM_RECLAIM, verify that the current process is not reclaiming memory or running on a workqueue which doesn't have the flag WQ_MEM_RECLAIM as that can break forward-progress guarantee leading to a deadlock.

https://notcve.org/view.php?id=CVE-2024-47695
In the Linux kernel, the following vulnerability has been resolved: RDMA/rtrs-clt: Reset cid to con_num - 1 to stay in bounds In the function init_conns(), after the create_con() and create_cm() for loop if something fails. In the cleanup for loop after the destroy tag, we access out of bound memory because cid is set to clt_path->s.con_num. This commits resets the cid to clt_path->s.con_num - 1, to stay in bounds in the cleanup loop later. • https://git.kernel.org/stable/c/6a98d71daea186247005099758af549e6afdd244 https://git.kernel.org/stable/c/0429a4e972082e3a2351da414b1c017daaf8aed2 https://git.kernel.org/stable/c/5ac73f8191f3de41fef4f934d84d97f3aadb301f https://git.kernel.org/stable/c/01b9be936ee8839ab9f83a7e84ee02ac6c8303c4 https://git.kernel.org/stable/c/1c50e0265fa332c94a4a182e4efa0fc70d8fad94 https://git.kernel.org/stable/c/c8b7f3d9fada0d4b4b7db86bf7345cd61f1d972e https://git.kernel.org/stable/c/3e4289b29e216a55d08a89e126bc0b37cbad9f38 •
