CVE-2026-74712

A flaw was found in the Linux kernel's vdpa/mlx5 driver. This vulnerability occurs due to an incorrect calculation of buffer length within the createdirectkeys function, causing the system to read beyond its allocated memory boundaries. A local attacker could exploit this memory corruption to...

CVE-2026-74712

In the Linux kernel, the following vulnerability has been resolved: vdpa/mlx5: Fix buffer length in createdirectkeys We have seen in our CI the following KASAN message: BUG: KASAN: slab-out-of-bounds in cmdexec+0x550/0xca0 mlx5core Read of size 272 at addr 0000000176795020 by task...

CVE-2026-74712

CVE-2026-74712 is a slab-out-of-bounds read in the Linux kernel's vdpa/mlx5 driver. The create_direct_keys() function incorrectly calculates the input buffer size by including the entire structure (out + in + mtt[]) while the pointer passed to cmd_exec targets only the in field. This causes mlx5_...

CVE-2026-74312

A flaw was found in the Linux kernel's vhost/vdpa subsystem. Improper validation of the virtqueue index in the vhostvdpammap and vhostvdpafault functions allows an out-of-range index to be used. This can lead to an out-of-bounds memory access in driver-specific callbacks, potentially causing...

CVE-2026-74309

A flaw was found in the Linux kernel's vdpa/octeonep component. This vulnerability involves an incorrect mapping of Interrupt Request IRQ numbers to processing rings within the interrupt handler. The system incorrectly calculates the IRQ index, which can lead to misdirected or mishandled...

CVE-2026-74312

The CVE-2026-74312 entries describe a Linux kernel vulnerability in vhost/vdpa where mmap and fault paths use vma->vm_pgoff as a virtqueue index without proper bounds validation against v->nvqs. This allowed an out-of-range queue index to reach driver callbacks via get_vq_notification(), un...

CVE-2026-74309

The CVE-2026-74309 entry documents a Linux kernel issue in the vdpa/octeon_ep component where interrupt handling incorrectly mapped IRQs to rings. The root cause is assuming irq - irqs[0] to locate the IRQ index; the fix updates the code to look up the IRQ index within oct_hw->irqs, allowing n...
