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...

kernel: xfrm: Update ipcomp_scratches with NULL when freed

In the Linux kernel, the following vulnerability has been resolved: xfrm: Update ipcompscratches with NULL when freed Currently if ipcompallocscratches fails to allocate memory ipcompscratches holds obsolete address. So when we try to free the percpu scratches using ipcompfreescratches it tries t...
