What to do

AI-suggested

A fix for this vulnerability has been implemented in the Linux kernel source code. Users should update to a Linux kernel version that includes this fix once it is released. Until then, avoid running 'perf record -e branches' on affected RISCV hardware to prevent triggering the panic.

Description

CVE-2024-26902 is a vulnerability in the Linux kernel's perf subsystem for RISCV architectures that causes a kernel panic due to improper bit setting in the pmu overflow handler. This flaw triggers a NULL pointer dereference when running 'perf record -e branches' on specific hardware such as the Sophgo sg2042, leading to a fatal kernel exception and system crash.
