There is no fixed version for Centos:10 kernel-debug-devel.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-debug-devel package and not the kernel-debug-devel package as distributed by Centos. See How to fix? for Centos:10 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

RDMA/umem: Be careful about boundary conditions in ib_umem_find_best_pgsz()

Several corner cases, especially important on 32 bits:

  • umem->iova is u64, the function argument should pass in u64 or iova will be truncated
  • Check that the length is not too large for the iova
  • Check that lengths > 4G don't overflow the GENMASK
