https://notcve.org/view.php?id=CVE-2024-42147
In the Linux kernel, the following vulnerability has been resolved: crypto: hisilicon/debugfs - Fix debugfs uninit process issue During the zip probe process, the debugfs failure does not stop the probe. When debugfs initialization fails, jumping to the error branch will also release regs, in addition to its own rollback operation. As a result, it may be released repeatedly during the regs uninit process. Therefore, the null check needs to be added to the regs uninit process. • https://git.kernel.org/stable/c/eda60520cfe3aba9f088c68ebd5bcbca9fc6ac3c https://git.kernel.org/stable/c/7fc8d9a525b5c3f8dfa5ed50901e764d8ede7e1e https://git.kernel.org/stable/c/e0a2d2df9ba7bd6bd7e0a9b6a5e3894f7e8445b3 https://git.kernel.org/stable/c/8be0913389718e8d27c4f1d4537b5e1b99ed7739 •
CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-42145 – IB/core: Implement a limit on UMAD receive List
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 •

In the Linux kernel, the following vulnerability has been resolved: vhost_task: Handle SIGKILL by flushing work and exiting Instead of lingering until the device is closed, this has us handle SIGKILL by: 1. marking the worker as killed so we no longer try to use it with new virtqueues and new flush operations. 2. setting the virtqueue to worker mapping so no new works are queued. 3. running all the exiting works. • https://git.kernel.org/stable/c/abe067dc3a662eef7d5cddbbc41ed50a0b68b0af https://git.kernel.org/stable/c/dec987fe2df670827eb53b97c9552ed8dfc63ad4 https://git.kernel.org/stable/c/db5247d9bf5c6ade9fd70b4e4897441e0269b233 •
