CVE-2026-46127 Details
Description
In the Linux kernel, the following vulnerability has been resolved: RDMA/ocrdma: Don't NULL deref uctx on errors in ocrdma_copy_pd_uresp() Sashiko points out that pd->uctx isn't initialized until late in the function so all these error flow references are NULL and will crash. Use the uctx that isn't NULL.
A vulnerability in the Linux kernel's RDMA/OCRDMA component can lead to a NULL pointer dereference. This issue occurs in the 'ocrdma_copy_pd_uresp' function, where the 'pd->uctx' variable is not initialized until later in the process. As a result, error handling references to 'pd->uctx' are NULL, causing a crash. The vulnerability affects the Linux kernel stable tree.
The vulnerability has been fixed in the Linux kernel. Users can upgrade to the latest version to address this issue.
