The vulnerability of the init_cea_offsets() function in the /arch/x86/mm/cpuEntryArea.c file of the Linux kernel’s memory management subsystem allows a attacker to access protected information and enhance their privileges.

The vulnerability of the initceaoffsets function in the /arch/x86/mm/cpuEntryArea.c file, belonging to the memory management subsystem of the Linux operating system, is related to the accessibility of the per-cpu memory area for user address space. Exploiting this vulnerability could allow an...
