Synopsis

The remote openSUSE host is missing a security update.

Description

The openSUSE Leap 15.1 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

- CVE-2020-12351: A type confusion while processing AMP packets could be used by physical close attackers to crash the kernel or potentially execute code was fixed (bsc#1177724).

- CVE-2020-12352: A stack information leak when handling certain AMP packets could be used by physical close attackers to leak information from the kernel was fixed (bsc#1177725).

- CVE-2020-25212: A TOCTOU mismatch in the NFS client code 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 (bnc#1176381).

- CVE-2020-25645: Traffic between two Geneve endpoints may be unencrypted when IPsec is configured to encrypt traffic for the specific UDP port used by the GENEVE tunnel allowing anyone between the two endpoints to read the traffic unencrypted. The main threat from this vulnerability is to data confidentiality (bnc#1177511).

The following non-security bugs were fixed :

- mm: memcg: switch to css_tryget() in get_mem_cgroup_from_mm() (bsc#1177685).

- mmc: core: do not set limits.discard_granularity as 0 (git-fixes).
