In the Linux kernel, the following vulnerability has been resolved: sctp: sysctl: cookie_hmac_alg: avoid using current->nsproxy As mentioned in a previous commit of this series, using the \'net\' structure via \'current\' is not recommended for different reasons: - Inconsistency: getting info from the reader\'s/writer\'s netns vs only from the opener\'s netns. - current->nsproxy can be NULL in some cases, resulting in an \'Oops\' (null-ptr-deref), e.g. when the current task is exiting, as spotted by syzbot [1] using acct(2). The \'net\' structure can be obtained from the table->data using container_of(). Note that table->data could also be used directly, as this is the only member needed from the \'net\' structure, but that would increase the size of this fix, to use \'*data\' everywhere \'net->sctp.sctp_hmac_alg\' is used.
