CVE-2024-49984

In the Linux kernel, the following vulnerability has been resolved: drm/v3d: Prevent out of bounds access in performance query extensions Check that the number of perfmons userspace is passing in the copy and reset extensions is not greater than the internal kernel storage where the ids will be...

CVE-2022-48987

In the Linux kernel, the following vulnerability has been resolved: media: v4l2-dv-timings.c: fix too strict blanking sanity checks Sanity checks were added to verify the v4l2bttimings blanking fields in order to avoid integer overflows when userspace passes weird values. But that assumed that...

CVE-2022-48987

CVE-2022-48987 affects the Linux kernel in media: v4l2-dv-timings.c. The issue was a misapplied blanking sanity check: when userspace supplies only a total blanking value, the total could be assigned to front porch, backporch, or sync fields, causing an overflow check to fail. The fix adds maximu...

SUSE CVE-2024-47727

In the Linux kernel, the following vulnerability has been resolved: x86/tdx: Fix "in-kernel MMIO" check TDX only supports kernel-initiated MMIO operations. The handlemmio function checks if the VE exception occurred in the kernel and rejects the operation if it did not. However, userspace can...

CVE-2024-47727

A flaw was found in the Linux kernel. Userspace can deceive the kernel into performing MMIO Memory-Mapped IO operations in TDX Trust Domain Extensions on its behalf, allowing a VE Virtualization Exception to be incorrectly handled as a in-kernel MMIO operation. Mitigation Mitigation for this issu...

CVE-2024-47742

In the Linux kernel, the following vulnerability has been resolved: firmwareloader: Block path traversal Most firmware names are hardcoded strings, or are constructed from fairly constrained format strings where the dynamic parts are just some hex numbers or such. However, there are a couple...

CVE-2024-47716

In the Linux kernel, the following vulnerability has been resolved: ARM: 9410/1: vfp: Use asm volatile in fmrx/fmxr macros Floating point instructions in userspace can crash some arm kernels built with clang/LLD 17.0.6: BUG: unsupported FP instruction in kernel mode FPEXC == 0xc0000780 Internal...

CVE-2024-47742

CVE-2024-47742 : Linux kernel firmware_loader path traversal vulnerability. Several code paths construct firmware filenames from device or userspace data (e.g., lpfc_sli4_request_firmware_update, nfp_net_fw_find, module_flash_fw_schedule). The issue arises when dynamic firmware names can include ...

CVE-2024-47727

CVE-2024-47727 is a Linux kernel issue (x86/tdx) where userspace could trick the kernel into performing MMIO via #VE by pointing a syscall at an MMIO address. The root cause was the in-kernel MMIO check in handle_mmio() not guaranteeing the target MMIO address was within the kernel before decodin...
