CVE-2020-25212

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.

The SUSE Linux Enterprise 12 SP4 kernel was updated to receive various security and bug fixes.

The following security bugs were fixed:

• CVE-2020-25705: A flaw in the way reply ICMP packets are limited in was found that allowed to quickly scan open UDP ports. This flaw allowed an off-path remote user to effectively bypassing source port UDP randomization. The highest threat from this vulnerability is to confidentiality and possibly integrity, because software and services that rely on UDP source port randomization (like DNS) are indirectly affected as well. Kernel versions may be vulnerable to this issue (bsc#1175721, bsc#1178782).

• livepatch: Test if -fdump-ipa-clones is really available As of now we add -fdump-ipa-clones unconditionally. It does not cause a trouble if the kernel is build with the supported toolchain. Otherwise it could fail easily. Do the correct thing and test for the availability.

It was discovered that the AMD Cryptographic Coprocessor device driver in the Linux kernel did not properly deallocate memory in some situations. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2019-18808)

It was discovered that the Conexant 23885 TV card device driver for the Linux kernel did not properly deallocate memory in some error conditions. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2019-19054)

It was discovered that the VFIO PCI driver in the Linux kernel did not properly handle attempts to access disabled memory spaces. A local attacker could use this to cause a denial of service (system crash). (CVE-2020-12888)

It was discovered that the state of network RNG in the Linux kernel was potentially observable. A remote attacker could use this to expose sensitive information. (CVE-2020-16166)

It was discovered that the NFS client implementation in the Linux kernel did not properly perform bounds checking before copying security labels in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-25212)
