Summary
In the Linux kernel, the following vulnerability has been resolved:
ptrace: slightly saner 'get_dumpable()' logic
The 'dumpability' of a task is fundamentally about the memory image of
the task - the concept comes from whether it can core dump or not - and
makes no sense when you don't have an associated mm.
And almost all users do in fact use it only for the case where the task
has a mm pointer.
But we have one odd special case: ptrace_may_access() uses 'dumpable' to
check various other things entirely independently of the MM (typically
explicitly using flags like PTRACE_MODE_READ_FSCREDS). Including for
threads that no longer have a VM (and maybe never did, like most kernel
threads).
It's not what this flag was designed for, but it is what it is.
The ptrace code does check that the uid/gid matches, so you do have to
be uid-0 to see kernel thread details, but this means that the
traditional "drop capabilities" model doesn't make any difference for
this all.
Make it all make a *bit* more sense by saying that if you don't have a
MM pointer, we'll use a cached "last dumpability" flag if the thread
ever had a MM (it will be zero for kernel threads since it is never
set), and require a proper CAP_SYS_PTRACE capability to override.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nptrace: slightly saner \u0027get_dumpable()\u0027 logic\n\nThe \u0027dumpability\u0027 of a task is fundamentally about the memory image of\nthe task - the concept comes from whether it can core dump or not - and\nmakes no sense when you don\u0027t have an associated mm.\n\nAnd almost all users do in fact use it only for the case where the task\nhas a mm pointer.\n\nBut we have one odd special case: ptrace_may_access() uses \u0027dumpable\u0027 to\ncheck various other things entirely independently of the MM (typically\nexplicitly using flags like PTRACE_MODE_READ_FSCREDS). Including for\nthreads that no longer have a VM (and maybe never did, like most kernel\nthreads).\n\nIt\u0027s not what this flag was designed for, but it is what it is.\n\nThe ptrace code does check that the uid/gid matches, so you do have to\nbe uid-0 to see kernel thread details, but this means that the\ntraditional \"drop capabilities\" model doesn\u0027t make any difference for\nthis all.\n\nMake it all make a *bit* more sense by saying that if you don\u0027t have a\nMM pointer, we\u0027ll use a cached \"last dumpability\" flag if the thread\never had a MM (it will be zero for kernel threads since it is never\nset), and require a proper CAP_SYS_PTRACE capability to override."
