| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2024-09-18 | CVE-2024-46761 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: pci/hotplug/pnv_php: Fix hotplug driver crash on Powernv The hotplug driver for powerpc (pci/hotplug/pnv_php.c) causes a kernel crash when we try to hot-unplug/disable the PCIe switch/bridge from the PHB. The crash occurs because although the MSI data structure has been released during disable/hot-unplug path and it has been assigned with NULL, still during unregistration the code was again trying to explicitly disable the MSI which causes the NULL pointer dereference and kernel crash. The patch fixes the check during unregistration path to prevent invoking pci_disable_msi/msix() since its data structure is already freed. | 5.5 |
| 2024-09-18 | CVE-2024-46762 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: xen: privcmd: Fix possible access to a freed kirqfd instance Nothing prevents simultaneous ioctl calls to privcmd_irqfd_assign() and privcmd_irqfd_deassign(). | 5.5 |

| 2024-09-18 | CVE-2024-46772 | Divide By Zero vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check denominator crb_pipes before used [WHAT & HOW] A denominator cannot be 0, and is checked before used. This fixes 2 DIVIDE_BY_ZERO issues reported by Coverity. | 5.5 |
| 2024-09-18 | CVE-2024-46773 | Divide By Zero vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check denominator pbn_div before used [WHAT & HOW] A denominator cannot be 0, and is checked before used. This fixes 1 DIVIDE_BY_ZERO issue reported by Coverity. | 5.5 |
| 2024-09-18 | CVE-2024-46774 | Out-of-bounds Write vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: powerpc/rtas: Prevent Spectre v1 gadget construction in sys_rtas() Smatch warns: arch/powerpc/kernel/rtas.c:1932 __do_sys_rtas() warn: potential spectre issue 'args.args' [r] (local cap) The 'nargs' and 'nret' locals come directly from a user-supplied buffer and are used as indexes into a small stack-based array and as inputs to copy_to_user() after they are subject to bounds checks. Use array_index_nospec() after the bounds checks to clamp these values for speculative execution. | 7.1 |
| 2024-09-18 | CVE-2024-46775 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Validate function returns [WHAT & HOW] Function return values must be checked before data can be used in subsequent functions. This fixes 4 CHECKED_RETURN issues reported by Coverity. | 5.5 |
