Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The issue is related to the Linux kernel's handling of mixed splice()/sendmsg(MSG ZEROCOPY) cases over the same TCP socket, which could trigger a warning in inet sock destruct(). The problem arises from the sendpage() path being forgotten, and the need for downgrading pure zerocopy status to keep sk forward alloc synced. This could potentially lead to a denial of service.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
