| CVE-2022-0322 | Med | 0.00 | 5.5 | 0.00 | Mar 25, 2022 | A flaw was found in the sctp_make_strreset_req function in net/sctp/sm_make_chunk.c in the SCTP network protocol in the Linux kernel with a local user privilege access. In this flaw, an attempt to use more buffer than is allocated triggers a BUG_ON issue, leading to a denial of… | ||
| CVE-2021-4203 | Med | 0.00 | 6.8 | 0.02 | Mar 25, 2022 | A use-after-free read flaw was found in sock_getsockopt() in net/core/sock.c due to SO_PEERCRED and SO_PEERGROUPS race with listen() (and connect()) in the Linux kernel. In this flaw, an attacker with a user privileges may crash the system or leak internal kernel information. | ||
| CVE-2022-0742 | Cri | 0.00 | 9.1 | 0.05 | Mar 18, 2022 | Memory leak in icmp6 implementation in Linux Kernel 5.13+ allows a remote attacker to DoS a host by making it go out-of-memory via icmp6 packets of type 130 or 131.
