mm/userfaultfd: fix hugetlb fault mutex hash calculation
In mfill_atomic_hugetlb(), linear_page_index() is used to calculate the
page index for hugetlb_fault_mutex_hash(). However, linear_page_index()
returns the index in PAGE_SIZE units, while hugetlb_fault_mutex_hash()
expects the index in huge page units. This mismatch means that different
addresses within the same huge page can produce different hash values,
leading to the use of different mutexes for the same huge page. This can
cause races between faulting threads, which can corrupt the reservation
map and trigger the BUG_ON in resv_map_release().
Fix this by introducing hugetlb_linear_page_index(), which returns the
page index in huge page granularity, and using it in place of
linear_page_index(). |
| In the Linux kernel, the following vulnerability has been resolved:
drm/i915: Unlink NV12 planes earlier
unlink_nv12_plane() will clobber parts of the plane state
potentially already set up by plane_atomic_check(), so we
must make sure not to call the two in the wrong order.
The problem happens when a plane previously selected as
a Y plane is now configured as a normal plane by user space.
plane_atomic_check() will first compute the proper plane
state based on the userspace request, and unlink_nv12_plane()
later clears some of the state.
This used to work on account of unlink_nv12_plane() skipping
the state clearing based on the plane visibility. But I removed
that check, thinking it was an impossible situation. Now when
that situation happens unlink_nv12_plane() will just WARN
and proceed to clobber the state.
Rather than reverting to the old way of doing things, I think
it's more clear if we unlink the NV12 planes before we even
compute the new plane state.

LoongArch: KVM: Fix base address calculation in kvm_eiointc_regs_access()
In function kvm_eiointc_regs_access(), the register base address is
caculated from array base address plus offset, the offset is absolute
value from the base address. The data type of array base address is
u64, it should be converted into the "void *" type and then plus the
offset. |

x86/cpu: Remove X86_CR4_FRED from the CR4 pinned bits mask
Commit in Fixes added the FRED CR4 bit to the CR4 pinned bits mask so
that whenever something else modifies CR4, that bit remains set. Which
in itself is a perfectly fine idea.
However, there's an issue when during boot FRED is initialized: first on
the BSP and later on the APs. Thus, there's a window in time when
exceptions cannot be handled.
This becomes particularly nasty when running as SEV-{ES,SNP} or TDX
guests which, when they manage to trigger exceptions during that short
window described above, triple fault due to FRED MSRs not being set up
yet.
See Link tag below for a much more detailed explanation of the
situation.
So, as a result, the commit in that Link URL tried to address this
shortcoming by temporarily disabling CR4 pinning when an AP is not
online yet.
However, that is a problem in itself because in this case, an attack on
the kernel needs to only modify the online bit - a single bit in RW
memory - and then disable CR4 pinning and then disable SM*P, leading to
more and worse things to happen to the system.
So, instead, remove the FRED bit from the CR4 pinning mask, thus
obviating the need to temporarily disable CR4 pinning.
If someone manages to disable FRED when poking at CR4, then
idt_invalidate() would make sure the system would crash'n'burn on the
first exception triggered, which is a much better outcome security-wise. |

idpf: fix PREEMPT_RT raw/bh spinlock nesting for async VC handling
Switch from using the completion's raw spinlock to a local lock in the
idpf_vc_xn struct. The conversion is safe because complete/_all() are
called outside the lock and there is no reason to share the completion
lock in the current logic. This avoids invalid wait context reported by
the kernel due to the async handler taking BH spinlock:

mm/damon/sysfs: dealloc repeat_call_control if damon_call() fails
damon_call() for repeat_call_control of DAMON_SYSFS could fail if somehow
the kdamond is stopped before the damon_call(). It could happen, for
example, when te damon context was made for monitroing of a virtual
address processes, and the process is terminated immediately, before the
damon_call() invocation. In the case, the dyanmically allocated
repeat_call_control is not deallocated and leaked.
Fix the leak by deallocating the repeat_call_control under the
damon_call() failure.

| In the Linux kernel, the following vulnerability has been resolved:
drm/xe: Fix missing runtime PM reference in ccs_mode_store
ccs_mode_store() calls xe_gt_reset() which internally invokes
xe_pm_runtime_get_noresume(). That function requires the caller
to already hold an outer runtime PM reference and warns if none
is held:
[46.891177] xe 0000:03:00.0: [drm] Missing outer runtime PM protection
[46.891178] WARNING: drivers/gpu/drm/xe/xe_pm.c:885 at
xe_pm_runtime_get_noresume+0x8b/0xc0
Fix this by protecting xe_gt_reset() with the scope-based
guard(xe_pm_runtime)(xe), which is the preferred form when
the reference lifetime matches a single scope.
v2:
- Use scope-based guard(xe_pm_runtime)(xe) (Shuicheng)
- Update commit message accordingly

| In the Linux kernel, the following vulnerability has been resolved:
pmdomain: bcm: bcm2835-power: Increase ASB control timeout
The bcm2835_asb_control() function uses a tight polling loop to wait
for the ASB bridge to acknowledge a request. During intensive workloads,
this handshake intermittently fails for V3D's master ASB on BCM2711,
resulting in "Failed to disable ASB master for v3d" errors during
runtime PM suspend. As a consequence, the failed power-off leaves V3D in
a broken state, leading to bus faults or system hangs on later accesses.
As the timeout is insufficient in some scenarios, increase the polling
timeout from 1us to 5us, which is still negligible in the context of a
power domain transition. Also, replace the open-coded ktime_get_ns()/
cpu_relax() polling loop with readl_poll_timeout_atomic(). |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: Fix the descriptor address in __kvm_at_swap_desc()
Using "(u64 __user *)hva + offset" to get the virtual addresses of S1/S2
descriptors looks really wrong, if offset is not zero. What we want to get
for swapping is hva + offset, not hva + offset*8. ;-)
Fix it. |
| In the Linux kernel, the following vulnerability has been resolved:
xfs: scrub: unlock dquot before early return in quota scrub
xchk_quota_item can return early after calling xchk_fblock_process_error.
When that helper returns false, the function returned immediately without
dropping dq->q_qlock, which can leave the dquot lock held and risk lock
leaks or deadlocks in later quota operations.
Fix this by unlocking dq->q_qlock before the early return. |
