Fixed In Version: kernel 6.1-rc1
Doc Type: If docs needed, set a value
Doc Text:
A memory leak flaw was found in the Linux kernel’s IPv6 functionality in how a user triggers the setsockopt of the IPV6_ADDRFORM and IPV6_DSTOPTS type. This flaw allows a user to crash the system if the setsockopt function is being called simultaneously with the IPV6_ADDRFORM type and other processes with the IPV6_DSTOPTS type. This issue is unlikely to happen unless a local process triggers IPV6_ADDRFORM.
