kernel: scsi: qedf: Make qedf_execute_tmf() non-preemptible

A vulnerability was found in the Linux kernel's qedf driver function qedfexecutetmf, where the function call smpprocessorid is done from preemptible code before acquiring a lock which can result in BUGON when running an RT kernel. This can result in system inconsistencies...

DEBIAN-CVE-2024-44968

In the Linux kernel, the following vulnerability has been resolved: tick/broadcast: Move per CPU pointer access into the atomic section The recent fix for making the take over of the broadcast timer more reliable retrieves a per CPU pointer in preemptible context. This went unnoticed as compilers...

CVE-2024-44968

The connected Nessus entry for CVE-2024-44968 confirms a Linux kernel tick/broadcast timer regression where per-CPU pointer access was taken in a preemptible region due to compiler behavior. The fix moves the per-CPU pointer retrieval to the actual usage site, which is in a non-preemptible region...

kernel: net: ntb_netdev: Move ntb_netdev_rx_handler() to call netif_rx() from __netif_rx()

A vulnerability was found in the Linux kernel in the ntbnetdevrxhandler function which calls the function netifrx, which can only be called from interrupt context, in a preemptible context. This vulnerability can lead to potential race conditions and system instability...

PT-2024-34011

Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: The issue concerns the use of smp processor id in preemptible code, which can lead to errors when the driver is enabled. The problem arises from the loongson3 cpufreq probe function...
