CVE-2023-52476 perf/x86/lbr: Filter vsyscall addresses

In the Linux kernel, the following vulnerability has been resolved: perf/x86/lbr: Filter vsyscall addresses We found that a panic can occur when a vsyscall is made while LBR sampling is active. If the vsyscall is interrupted NMI for perf sampling, this call sequence can occur most recent at top:...

CVE-2023-52476

CVE-2023-52476 refers to a Linux kernel vulnerability in the perf/x86/lbr path where a panic can occur if a vsyscall is made while LBR sampling is active. The issue arises when a vsyscall interrupt (NMI) leads to a decode path that dereferences next_byte pointing to the vsyscall address (e.g., ge...

CVE-2021-46971

The CVE-2021-46971 entry corresponds to a Linux kernel fix in perf/core: the lockdown state was queried unconditionally, but its result is only needed if PERF_SAMPLE_REGS_INTR is set in attr.sample_type. This unconditional check could trigger SELinux lockdown hooks unnecessarily, potentially caus...
