CVE-2022-49001

CVE-2022-49001 describes a race condition in the Linux kernel riscv path where, during vmap stack overflow handling, multiple harts can contend on the same shadow stack. The root cause is a race between switching to the shadow stack and calling get_overflow_stack() when more than one hart uses th...
