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.",

Title
net: shaper: protect late read accesses to the hierarchy
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: shaper: protect late read accesses to the hierarchy
We look up a netdev during prep of Netlink ops (pre- callbacks)
and take a ref to it. Then later in the body of the callback
we take its lock or RCU which are the actual protections.
This is not proper, a conversion from a ref to a locked netdev
must include a liveness check (a check if the netdev hasn't been
unregistered already). Fix the read cases (those under RCU).
Writes needs a separate change to protect from creating the
hierarchy after flush has already run.
Severity
7.8 (High)

Title
xfrm: Fix work re-schedule after cancel in xfrm_nat_keepalive_net_fini()
Summary
In the Linux kernel, the following vulnerability has been resolved:
xfrm: Fix work re-schedule after cancel in xfrm_nat_keepalive_net_fini()
After cancel_delayed_work_sync() is called from
xfrm_nat_keepalive_net_fini(), xfrm_state_fini() flushes remaining
states via __xfrm_state_delete(), which calls
xfrm_nat_keepalive_state_updated() to re-schedule nat_keepalive_work.
The following is a simple race scenario:
cpu0 cpu1
cleanup_net() [Round 1]
ops_undo_list()
xfrm_net_exit()
xfrm_nat_keepalive_net_fini()
cancel_delayed_work_sync(nat_keepalive_work);
xfrm_state_fini()
xfrm_state_flush()
xfrm_state_delete(x)
__xfrm_state_delete(x)
xfrm_nat_keepalive_state_updated(x)
schedule_delayed_work(nat_keepalive_work);
rcu_barrier();
net_complete_free();
net_passive_dec(net);
llist_add(&net->defer_free_list, &defer_free_list);
cleanup_net() [Round 2]
rcu_barrier();
net_complete_free()
kmem_cache_free(net_cachep, net);
nat_keepalive_work()
// on freed net
To prevent this, cancel_delayed_work_sync() is replaced with
disable_delayed_work_sync().

Title
net: skbuff: preserve shared-frag marker during coalescing
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: skbuff: preserve shared-frag marker during coalescing
skb_try_coalesce() can attach paged frags from @from to @to. If @from
has SKBFL_SHARED_FRAG set, the resulting @to skb can contain the same
externally-owned or page-cache-backed frags, but the shared-frag marker
is currently lost.
That breaks the invariant relied on by later in-place writers. In
particular, ESP input checks skb_has_shared_frag() before deciding
whether an uncloned nonlinear skb can skip skb_cow_data(). If TCP
receive coalescing has moved shared frags into an unmarked skb, ESP can
see skb_has_shared_frag() as false and decrypt in place over page-cache
backed frags.
Propagate SKBFL_SHARED_FRAG when skb_try_coalesce() transfers paged
frags. The tailroom copy path does not need the marker because it copies
bytes into @to's linear data rather than transferring frag descriptors.

Title
ptrace: slightly saner 'get_dumpable()' logic
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."

"value": "AV:L - The vulnerable authorization check is reached through local interfaces such as ptrace-style checks, procfs, and pidfd_getfd; it is not reachable from network packets or adjacent/physical input.\nAC:L - A local attacker can repeatedly trigger the relevant check and, for exiting tasks, can race pidfd_getfd/procfs access against a target\u0027s exit path after exit_mm() but before exit_files(). The race is attacker-driven and does not require unusual kernel configuration or conditions outside the attacker\u0027s influence.\nPR:L - An unprivileged local user can target same-UID nondumpable tasks because the vulnerable code skips the dumpability requirement once task-\u003emm is NULL. User-namespace root does not help against init-namespace root kernel threads, but low local privileges are enough for the same-UID exiting-task case.\nUI:N - Exploitation does not require a victim user to open a file or perform an interactive action; the attacker can use local syscalls/procfs against an existing or attacker-terminated target task.\nS:U - The bug bypasses Linux kernel task-access authorization within the same OS security authority. It does not cross a VM, IOMMU, or hypervisor boundary.\nC:H - The bypass can allow access to sensitive task details and, most importantly, pidfd_getfd can duplicate file descriptors from a nondumpable task during the exit window. In a plausible helper/sandbox scenario, those descriptors can expose highly sensitive files or privileged resources.\nI:H - If the duplicated descriptor is writable, the attacker can modify the protected resource reachable through the victim\u0027s file descriptor despite the dumpability restriction. This is a high-impact integrity bypass even though the bug is not memory corruption.\nA:N - The issue is an access-control bypass around ptrace/dumpability checks and does not by itself provide a kernel crash, hang, deadlock, or sustained denial of service."
