This is related to the cgroups feature. | ||
| CVE-2020-25212 | Hig | 0.00 | 7.0 | 0.00 | Sep 9, 2020 | A TOCTOU mismatch in the NFS client code in the Linux kernel before 5.8.3 could be used by local attackers to corrupt memory or possibly have unspecified other impact because a size check is in fs/nfs/nfs4proc.c instead of fs/nfs/nfs4xdr.c, aka CID-b4487b935452. | ||
| CVE-2020-25211 | Med | 0.00 | 6.0 | 0.01 | Sep 9, 2020 | In the Linux kernel through 5.8.7, local attackers able to inject conntrack netlink configuration could overflow a local buffer, causing crashes or triggering use of incorrect protocol numbers in ctnetlink_parse_tuple_filter in net/netfilter/nf_conntrack_netlink.c, aka… | ||
| CVE-2020-10720 | Med | 0.00 | 5.5 | 0.00 | Sep 3, 2020 | A flaw was found in the Linux kernel's implementation of GRO in versions before 5.2. This flaw allows an attacker with local access to crash the system. | ||
