In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Discard command completions in internal error Fix use after free when FW completion arrives while device is in internal error state. Avoid calling completion handler in this case, since the device will flush the command interface and trigger all completions manually.

CVSS: -EPSS: 0%CPEs: 10EXPL: 0CVE-2024-38554 – ax25: Fix reference count leak issue of net_device
https://notcve.org/view.php?id=CVE-2024-38554
In the Linux kernel, the following vulnerability has been resolved: ax25: Fix reference count leak issue of net_device There is a reference count leak issue of the object "net_device" in ax25_dev_device_down(). When the ax25 device is shutting down, the ax25_dev_device_down() drops the reference count of net_device one or zero times depending on if we goto unlock_put or not, which will cause memory leak. In order to solve the above issue, decrease the reference count of net_device after dev->ax25_ptr is set to null. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ax25: Solucionar el problema de fuga del recuento de referencias de net_device Hay un problema de fuga del recuento de referencias del objeto "net_device" en ax25_dev_device_down(). Cuando el dispositivo ax25 se está apagando, ax25_dev_device_down() elimina el recuento de referencia de net_device una o cero veces dependiendo de si vamos a unlock_put o no, lo que provocará una pérdida de memoria. Para resolver el problema anterior, reduzca el recuento de referencias de net_device después de que dev->ax25_ptr se establezca en nulo. • https://git.kernel.org/stable/c/d01ffb9eee4af165d83b08dd73ebdf9fe94a519b https://git.kernel.org/stable/c/ef0a2a0565727a48f2e36a2c461f8b1e3a61922d https://git.kernel.org/stable/c/e2b558fe507a1ed4c43db2b0057fc6e41f20a14c https://git.kernel.org/stable/c/418993bbaafb0cd48f904ba68eeda052d624c821 https://git.kernel.org/stable/c/5ea00fc60676c0eebfa8560ec461209d638bca9d https://git.kernel.org/stable/c/9af0fd5c4453a44c692be0cbb3724859b75d739b https://git.kernel.org/stable/c/3ec437f9bbae68e9b38115c4c91de995f73f6bad https://git.kernel.org/stable/c/965d940fb7414b310a22666503d2af694 •

https://notcve.org/view.php?id=CVE-2024-38553
In the Linux kernel, the following vulnerability has been resolved: net: fec: remove .ndo_poll_controller to avoid deadlocks There is a deadlock issue found in sungem driver, please refer to the commit ac0a230f719b ("eth: sungem: remove .ndo_poll_controller to avoid deadlocks"). The root cause of the issue is that netpoll is in atomic context and disable_irq() is called by .ndo_poll_controller interface of sungem driver, however, disable_irq() might sleep. After analyzing the implementation of fec_poll_controller(), the fec driver should have the same issue. Due to the fec driver uses NAPI for TX completions, the .ndo_poll_controller is unnecessary to be implemented in the fec driver, so fec_poll_controller() can be safely removed. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: fec: elimine .ndo_poll_controller para evitar interbloqueos. • https://git.kernel.org/stable/c/7f5c6addcdc039c1a7c435857e6284ecac5d97c8 https://git.kernel.org/stable/c/e2348d8c61d03feece1de4c05f72e6e99f74c650 https://git.kernel.org/stable/c/d38625f71950e79e254515c5fc585552dad4b33e https://git.kernel.org/stable/c/accdd6b912c4219b8e056d1f1ad2e85bc66ee243 https://git.kernel.org/stable/c/87bcbc9b7e0b43a69d44efa5f32f11e32d08fa6f https://git.kernel.org/stable/c/c2e0c58b25a0a0c37ec643255558c5af4450c9f5 •

https://notcve.org/view.php?id=CVE-2024-38552
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix potential index out of bounds in color transformation function Fixes index out of bounds issue in the color transformation function. The issue could occur when the index 'i' exceeds the number of transfer function points (TRANSFER_FUNC_POINTS). The fix adds a check to ensure 'i' is within bounds before accessing the transfer function points. If 'i' is out of bounds, an error message is logged and the function returns false to indicate an error.
