kernel: Out of boundary write in perf_read_group() as result of overflow a perf_event's read_size

A flaw was found in the Linux kernel's Performance Events system component. A condition can be triggered that allows data to be written past the end or before the beginning of the intended memory buffer. This may lead to a system crash, code execution, or local privilege escalation...

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...
