Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A use-after-free issue in the Linux kernel's tcp component has been resolved. The issue occurred in the
reqsk timer handler() function and was caused by the incorrect handling of the nreq variable. The commit that fixed the issue replaced inet csk reqsk queue drop and put() with inet csk reqsk queue drop() and reqsk put() in reqsk timer handler(). To prevent the use-after-free issue, oreq should be passed to reqsk put() instead of req. This issue could occur when reqsk is migrated but the retry attempt fails, for example, due to a timeout.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
