Kernel: NULL pointer dereference problem in sctp_sched_dequeue_common

A NULL pointer dereference issue was found in the SCTP network protocol in net/sctp/streamsched.c in the Linux kernel. If streamin allocation fails, streamout is freed, which would be accessed further. This flaw allows a local user to crash the system or potentially cause a denial of service...

kernel: sctp: check send stream number after wait_for_sndbuf

In the Linux kernel, the following vulnerability has been resolved: sctp: check send stream number after waitforsndbuf This patch fixes a corner case where the asoc out stream count may change after waitforsndbuf. When the main thread in the client starts a connection, if its out stream count is...

kernel: sctp: fix a potential overflow in sctp_ifwdtsn_skip

In the Linux kernel, the following vulnerability has been resolved: sctp: fix a potential overflow in sctpifwdtsnskip Currently, when traversing ifwdtsn skips with sctpwalkifwdtsn, it only checks the pos against the end of the chunk. However, the data left for the last pos may be sizeofstruct...
