PT-2021-8001 · Linux · Linux Kernel

Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: The issue is related to a possible null-pointer dereference in the KVM subsystem of the Linux kernel. This occurs when using the created vcpus parameter instead of online vcpus to...

CVE-2021-28971

A flaw was found in the Linux kernel. On some Haswell CPUs, userspace applications such as perf-fuzzer can cause a system crash because the PEBS status in a PEBS record is mishandled. Mitigation Mitigation for this issue is either not available or the currently available options does not meet the...

PlayStation: SMAP bypass

SMAP is a security feature on x86 CPUs, that forbids ring0 from reading/writing to ring3 pages, making it harder to exploit entire classes of vulnerabilities. There is a vulnerability in FreeBSD 12 that allows SMAP to be bypassed by userland. There is a very high probability that it affects the P...
