CVE-2026-72393

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

Description A slab-use-after-free issue exists in the Linux kernel within the fbnic tx lso() function. The function calls skb cow head(), which can reallocate the socket buffer (skb), including its shared information. If a pointer to the shared information is calculated before this call and used afterward, it may point to memory that has already been freed.

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