AI-suggested
A fix is available that properly bounds the num_sge and cur_sge values before indexing the sge array in the RDMA rxe driver. Users should apply the vendor-provided patches or update to fixed kernel versions to remediate this issue.
Description
A vulnerability in the Linux kernel's RDMA rxe driver allows a local unprivileged user to cause an out-of-bounds read in kernel memory. This occurs because user-supplied Work Queue Elements (WQEs) are not properly validated before indexing an array, leading to a potential local denial of service. The issue has been resolved by adding proper bounds checks on the number of scatter-gather entries before use.
