CVE-2026-74719

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the smc llc event handler() function where the SMC LLC CONFIRM LINK and SMC LLC ADD LINK CONT branches store an incoming qentry into the local LLC flow without verifying if a qentry is already pending. If a peer sends a second CONFIRM LINK or ADD LINK CONT request while a flow is active and flow->qentry is already set, the smc llc flow qentry set() function overwrites the pointer without freeing the previous allocation. This results in a memory leak of one kmalloc-96 object per spurious message.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
