https://notcve.org/view.php?id=CVE-2024-42145
In the Linux kernel, the following vulnerability has been resolved: IB/core: Implement a limit on UMAD receive List The existing behavior of ib_umad, which maintains received MAD packets in an unbounded list, poses a risk of uncontrolled growth. As user-space applications extract packets from this list, the rate of extraction may not match the rate of incoming packets, leading to potential list overflow. To address this, we introduce a limit to the size of the list. After considering typical scenarios, such as OpenSM processing, which can handle approximately 100k packets per second, and the 1-second retry timeout for most packets, we set the list size limit to 200k. Packets received beyond this limit are dropped, assuming they are likely timed out by the time they are handled by user-space. Notably, packets queued on the receive list due to reasons like timed-out sends are preserved even when the list is full. • https://git.kernel.org/stable/c/1288cf1cceb0e6df276e182f5412370fb4169bcb https://git.kernel.org/stable/c/b4913702419d064ec4c4bbf7270643c95cc89a1b https://git.kernel.org/stable/c/62349fbf86b5e13b02721bdadf98c29afd1e7b5f https://git.kernel.org/stable/c/d73cb8862e4d6760ccc94d3b57b9ef6271400607 https://git.kernel.org/stable/c/63d202d948bb6d3a28cd8e8b96b160fa53e18baa https://git.kernel.org/stable/c/b8c5f635997f49c625178d1a0cb32a80ed33abe6 https://git.kernel.org/stable/c/a6627fba793cc75b7365d9504a0095fb2902dda4 https://git.kernel.org/stable/c/ca0b44e20a6f3032224599f02e7c8fb49 •

https://notcve.org/view.php?id=CVE-2024-42137
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: qca: Fix BT enable failure again for QCA6390 after warm reboot Commit 272970be3dab ("Bluetooth: hci_qca: Fix driver shutdown on closed serdev") will cause below regression issue: BT can't be enabled after below steps: cold boot -> enable BT -> disable BT -> warm reboot -> BT enable failure if property enable-gpios is not configured within DT|ACPI for QCA6390. The commit is to fix a use-after-free issue within qca_serdev_shutdown() by adding condition to avoid the serdev is flushed or wrote after closed but also introduces this regression issue regarding above steps since the VSC is not sent to reset controller during warm reboot. Fixed by sending the VSC to reset controller within qca_serdev_shutdown() once BT was ever enabled, and the use-after-free issue is also fixed by this change since the serdev is still opened before it is flushed or wrote.
