https://notcve.org/view.php?id=CVE-2024-36004
In the Linux kernel, the following vulnerability has been resolved: i40e: Do not use WQ_MEM_RECLAIM flag for workqueue Issue reported by customer during SRIOV testing, call trace: When both i40e and the i40iw driver are loaded, a warning in check_flush_dependency is being triggered. This seems to be because of the i40e driver workqueue is allocated with the WQ_MEM_RECLAIM flag, and the i40iw one is not. Similar error was encountered on ice too and it was fixed by removing the flag. Do the same for i40e too.

CVSS: 5.5EPSS: 0%CPEs: 8EXPL: 0CVE-2024-35997 – HID: i2c-hid: remove I2C_HID_READ_PENDING flag to prevent lock-up
https://notcve.org/view.php?id=CVE-2024-35997
In the Linux kernel, the following vulnerability has been resolved: HID: i2c-hid: remove I2C_HID_READ_PENDING flag to prevent lock-up The flag I2C_HID_READ_PENDING is used to serialize I2C operations. However, this is not necessary, because I2C core already has its own locking for that. More importantly, this flag can cause a lock-up: if the flag is set in i2c_hid_xfer() and an interrupt happens, the interrupt handler (i2c_hid_irq) will check this flag and return immediately without doing anything, then the interrupt handler will be invoked again in an infinite loop. Since interrupt handler is an RT task, it takes over the CPU and the flag-clearing task never gets scheduled, thus we have a lock-up. Delete this unnecessary flag. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: HID: i2c-hid: elimine el indicador I2C_HID_READ_PENDING para evitar el bloqueo. El indicador I2C_HID_READ_PENDING se utiliza para serializar operaciones I2C. Sin embargo, esto no es necesario, porque el núcleo I2C ya tiene su propio bloqueo para ello. Más importante aún, este indicador puede causar un bloqueo: si el indicador está configurado en i2c_hid_xfer() y ocurre una interrupción, el controlador de interrupciones (i2c_hid_irq) verificará este indicador y regresará inmediatamente sin hacer nada, entonces se invocará el controlador de interrupciones. nuevamente en un bucle infinito. • https://git.kernel.org/stable/c/4a200c3b9a40242652b5734630bdd0bcf3aca75f https://git.kernel.org/stable/c/21bfca822cfc1e71796124e93b46e0d9fa584401 https://git.kernel.org/stable/c/c448a9fd50f77e8fb9156ff64848aa4295eb3003 https://git.kernel.org/stable/c/5095b93021b899f54c9355bebf36d78854c33a22 https://git.kernel.org/stable/c/b65fb50e04a95eec34a9d1bc138454a98a5578d8 https://git.kernel.org/stable/c/0561b65fbd53d3e788c5b0222d9112ca016fd6a1 https://git.kernel.org/stable/c/29e94f295bad5be59cf4271a93e22cdcf5536722 https://git.kernel.org/stable/c/418c5575d56410c6e186ab727bf32ae32 • CWE-400: Uncontrolled Resource Consumption CWE-667: Improper Locking •
