kernel: race condition in perf_event_open leads to privilege escalation
A use-after-free flaw was found in the Linux kernel’s performance events functionality. A user triggers a race condition in setting up performance monitoring between the leading PERFTYPETRACEPOINT and sub PERFEVENTHARDWARE plus the PERFEVENTSOFTWARE using the perfeventopen function with these thr...

GSD-2022-1002324 KVM: x86/svm: Clear reserved bits written to PerfEvtSeln MSRs
KVM: x86/svm: Clear reserved bits written to PerfEvtSeln MSRs This is an automated ID intended to aid in discovery of potential security vulnerabilities. The actual impact and attack plausibility have not yet been proven. This ID is fixed in Linux Kernel version v4.19.238 by commit...
AZL-6542 CVE-2021-28971 affecting package kernel for versions less than 5.10.78.1-1
In intelpmudrainpebsnhm in arch/x86/events/intel/ds.c in the Linux kernel through 5.11.8 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, aka CID-d88d05a9e0b6...
kernel: performance counters race condition use-after-free
A flaw was found in the Linux kernel. A use-after-free memory flaw was found in the perf subsystem allowing a local attacker with permission to monitor perf events to corrupt memory and possibly escalate privileges. The highest threat from this vulnerability is to data confidentiality and integri...
Debian DLA-2483-1 : linux-4.19 security update
Several vulnerabilities have been discovered in the Linux kernel that may lead to the execution of arbitrary code, privilege escalation, denial of service or information leaks. CVE-2019-19039 'Team bobfuzzer' reported a bug in Btrfs that could lead to an assertion failure WARN. A user permitted t...

Privilege Escalation
kernel is vulnerable to privilege escalation. The vulnerability exists as it was found that the perf tool, a part of the Linux kernel's Performance Events implementation, could load its configuration file from the current working directory. If a local user with access to the perf tool were tricke...
Denial Of Service (DoS)
kernel is vulnerable to denial of service DoS. The vulnerability exists as a flaw was found in the Linux kernel's Performance Events implementation. It could falsely lead the NMI Non-Maskable Interrupt Watchdog to detect a lockup and panic the system. A local, unprivileged user could use this fla...
Privilege Escalation
The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues: A heap-based buffer overflow flaw was found in the Linux kernel's iSCSI target subsystem. A remote attacker could use a specially-crafted iSCSI request to caus...

Denial Of Service (DoS)
kernel-rt is vulnerable to denial of service. A flaw was found in the Linux kernel's Performance Events implementation. On systems with certain Intel processors, a local, unprivileged user could use this flaw to cause a denial of service by leveraging the perf subsystem to write into the reserved...

CVE-2018-12714
An issue was discovered in the Linux kernel through 4.17.2. The filter parsing in kernel/trace/traceeventsfilter.c could be called with no filter, which is an N=0 case when it expected at least one line to have been read, thus making the N-1 index invalid. This allows attackers to cause a denial ...
kernel: Race condition between multiple sys_perf_event_open() calls
It was found that the original fix for CVE-2016-6786 was incomplete. There exist a race between two concurrent sysperfeventopen calls when both try and move the same pre-existing software group into a hardware context...
