MEDIUM 5.5EPSS 0.68%
Does this matter?
Lower severity and a low EPSS score (0.68%). Track it; it rarely justifies an emergency change on its own.
Description
In calc_vm_may_flags of ashmem.c, there is a possible arbitrary write to shared memory due to a permissions bypass. This could lead to local escalation of privilege by corrupting memory shared between processes, with no additional execution privileges needed. User interaction is not needed for exploitation.
