{"id":"DEBIAN-CVE-2024-57903","details":"In the Linux kernel, the following vulnerability has been resolved:  net: restrict SO_REUSEPORT to inet sockets  After blamed commit, crypto sockets could accidentally be destroyed from RCU call back, as spotted by zyzbot [1].  Trying to acquire a mutex in RCU callback is not allowed.  Restrict SO_REUSEPORT socket option to inet sockets.  v1 of this patch supported TCP, UDP and SCTP sockets, but fcnal-test.sh test needed RAW and ICMP support.
