In the Linux kernel, the following vulnerability has been resolved: Bluetooth: MGMT: Add error handling to pair_device() hci_conn_params_add() never checks for a NULL value and could lead to a NULL pointer dereference causing a crash. Fixed by adding error handling in the function. • https://git.kernel.org/stable/c/5157b8a503fa834e8569c7fed06981e3d3d53db0 https://git.kernel.org/stable/c/11b4b0e63f2621b33b2e107407a7d67a65994ca1 https://git.kernel.org/stable/c/90e1ff1c15e5a8f3023ca8266e3a85869ed03ee9 https://git.kernel.org/stable/c/9df9783bd85610d3d6e126a1aca221531f6f6dcb https://git.kernel.org/stable/c/951d6cb5eaac5130d076c728f2a6db420621afdb https://git.kernel.org/stable/c/5da2884292329bc9be32a7778e0e119f06abe503 https://git.kernel.org/stable/c/064dd929c76532359d2905d90a7c12348043cfd4 https://git.kernel.org/stable/c/ee0799103b1ae4bcfd80dc11a15df085f •

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 •

In the Linux kernel, the following vulnerability has been resolved: bpf: Add schedule points in batch ops syzbot reported various soft lockups caused by bpf batch operations. INFO: task kworker/1:1:27 blocked for more than 140 seconds. INFO: task hung in rcu_barrier Nothing prevents batch ops to process huge amount of data, we need to add schedule points in them. Note that maybe_wait_bpf_programs(map) calls from generic_map_delete_batch() can be factorized by moving the call after the loop. This will be done later in -next tree once we get this fix merged, unless there is strong opinion doing this optimization sooner. • https://git.kernel.org/stable/c/aa2e93b8e58e18442edfb2427446732415bc215e https://git.kernel.org/stable/c/7ef94bfb08fb9e73defafbd5ddef6b5a0e2ee12b https://git.kernel.org/stable/c/8628f489b749a4f9767991631921dbe3fbcdc784 https://git.kernel.org/stable/c/7e8099967d0e3ff9d1ae043e80b27fbe46c08417 https://git.kernel.org/stable/c/75134f16e7dd0007aa474b281935c5f42e79f2c8 https://access.redhat.com/security/cve/CVE-2022-48939 https://bugzilla.redhat.com/show_bug.cgi?id=2307195 • CWE-834: Excessive Iteration •

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/a612395c7631918e0e10ea48b9ce5ab4340f26a6 https://git.kernel.org/stable/c/9957fbf34f52a4d8945d1bf39aae400ef9a11246 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 •
