CVE-2026-97960
A flaw was found in the Linux kernel. A concurrency issue in the Intel Performance Monitoring Unit PMU subsystem allows the Precise Event-Based Sampling PEBS buffer draining routine to be re-entered unexpectedly. A local user could exploit this flaw while configuring performance events to trigger...
PT-2026-98624
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the Linux kernel where the drain pebs function can be reentered. Because the PEBS buffer is shared by all events on a CPU, reentry can lead to an instance observing...
Linux Kernel Security Vulnerabilities
The Linux kernel versions from 6.3.7 to 6.4 and 6.4 itself have security vulnerabilities. These vulnerabilities stem from the fact that the PEBS buffer is shared among all events on the CPU. The function drainpebs is reentrant; during reentry, expired buffer states may be observed, and...
