CVE-2022-50850

CVE-2022-50850 affects the Linux kernel component: scsi/ipr. The issue described is a WARNING raised when ipr_init() calls unregister_reboot_notifier() if pci_register_driver() fails, leading to a logged WARN and a notifier chain risk. Patches fix the root cause by ensuring unregister_reboot_noti...

CVE-2023-54234

In the Linux kernel, the following vulnerability has been resolved: scsi: mpi3mr: Fix missing mrioc-evtackcmds initialization Commit c1af985d27da "scsi: mpi3mr: Add Event acknowledgment logic" introduced an array mrioc-evtackcmds but initialization of the array elements was missed. They are just...

CVE-2023-54234

The CVE-2023-54234 issue is concrete: in the Linux kernel, the MPI3 MR SCSI driver (scsi: mpi3mr) had an uninitialized mrioc->evtack_cmds array, causing mpi3mr_complete_evt_ack() to access host_tag fields that were zeroed. This could lead to incorrect bit indexing when clearing mrico->evtac...

CVE-2023-54206

The CVE is a Linux kernel issue in net/sched/flower where an idr initialization was moved too early in fl_change(), allowing a concurrently initialized filter to be accessed and potentially dereferenced. The published fix inserts a NULL pointer into idr early to allocate a handle but ensures fl_g...

CVE-2022-50847 drm/bridge: it6505: Initialize AUX channel in it6505_i2c_probe

In the Linux kernel, the following vulnerability has been resolved: drm/bridge: it6505: Initialize AUX channel in it6505i2cprobe During device boot, the HPD interrupt could be triggered before the DRM subsystem registers it6505 as a DRM bridge. In such cases, the driver tries to access AUX channe...

CVE-2023-54167 m68k: mm: Move initrd phys_to_virt handling after paging_init()

In the Linux kernel, the following vulnerability has been resolved: m68k: mm: Move initrd phystovirt handling after paginginit When booting with an initial ramdisk on platforms where physical memory does not start at address zero e.g. on Amiga: initrd: 0ef0602c - 0f800000 Zone ranges: DMA mem...

CVE-2023-54167

The CVE-2023-54167 issue concerns the Linux kernel on m68k where phys_to_virt handling for the initrd was performed before paging_init, causing an access fault on boot with an initial ramdisk on non-zero start memory architectures (e.g., Amiga). The fix postpones phys_to_virt initialization until...

CVE-2022-50820

CVE-2022-50820 affects the Linux kernel, specifically in the perf/arm_dmc620 subsystem. The vulnerability arises in dmc620_pmu_init(), which may leak a hotplug callback because a callback registered with cpuhp_setup_state_multi() is not removed if platform_driver_register() fails. The documented ...
