CVE-2026-31534 Details
Description
Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.
A vulnerability in the Linux kernel's SMB client has been addressed. The issue arose in the 'smbdirect_send_batch' processing, where requests could be sent without the 'IB_SEND_SIGNALED' flag. This omission would lead to problems when the final request, which did have the flag set, was processed. If the connection was interrupted, all requests would be signaled, even those without explicit acknowledgment. The vulnerability could cause 'use-after-free' issues by improperly managing the memory of sibling requests.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for downloading the patched version are available on the Linux kernel's official website.
