Details

In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Fix repeated calls to sockput() when msg has moredata In tcpbpfsendverdict() redirection, the eval variable is assigned to _SKREDIRECT after the applybytes data is sent, if msg has moredata, sockput() will be called multiple times. We should reset the eval variable to _SKNONE every time moredata starts. This causes: IPv4: Attempt to release TCP socket in state 1 00000000b4c925d7 ------------[ cut here ]------------ refcountt: addition on 0; use-after-free.
