A vulnerability was found in the NFS module of the Linux kernel, where a potential system crash (Oops) occurred due to improper handling of the mirror array in __nfs_pageio_add_request(). The nfs_pageio_error_cleanup() function did not correctly reset the mirror array, leading to inconsistencies when the structure was empty.
Red Hat has investigated whether a possible mitigation exists for this issue, and has not been able to identify a practical example. Please update the affected package as soon as possible.
