The SUSE Linux Enterprise 15 SP2 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : CVE-2019-19462: relayopen in kernel/relay.c in the Linux kernel allowed local users to cause a denial of service such as relay blockage by triggering a NULL...

kernel: Indirect branch speculation can be enabled after it was force-disabled by the PR_SPEC_FORCE_DISABLE prctl command.

A flaw was found in the prctl function, where it can be used to enable indirect branch speculation after it has been disabled. This call incorrectly reports it as being 'force disabled' when it is not and opens the system to Spectre v2 attacks. The highest threat from this vulnerability is to...

kernel: Indirect Branch Prediction Barrier is force-disabled when STIBP is unavailable or enhanced IBRS is available.

A flaw was found in the Linux kernel’s implementation of the Enhanced IBPB Indirect Branch Prediction Barrier. The IBPB mitigation will be disabled when STIBP is not available or when the Enhanced Indirect Branch Restricted Speculation IBRS is available. This flaw allows a local attacker to perfo...
