Title
efivarfs: force RO when remounting if SetVariable is not supported
Summary
In the Linux kernel, the following vulnerability has been resolved:
efivarfs: force RO when remounting if SetVariable is not supported
If SetVariable at runtime is not supported by the firmware we never assign
a callback for that function. At the same time mount the efivarfs as
RO so no one can call that. However, we never check the permission flags
when someone remounts the filesystem as RW. As a result this leads to a
crash looking like this:
$ mount -o remount,rw /sys/firmware/efi/efivars
$ efi-updatevar -f PK.auth PK

Fix this by adding a .reconfigure() function to the fs operations which
we can use to check the requested flags and deny anything that's not RO
if the firmware doesn't implement SetVariable at runtime.

Title
nfsd: fix RELEASE_LOCKOWNER
Summary
In the Linux kernel, the following vulnerability has been resolved:
nfsd: fix RELEASE_LOCKOWNER
The test on so_count in nfsd4_release_lockowner() is nonsense and
harmful. Revert to using check_for_locks(), changing that to not sleep.
First: harmful.
As is documented in the kdoc comment for nfsd4_release_lockowner(), the
test on so_count can transiently return a false positive resulting in a
return of NFS4ERR_LOCKS_HELD when in fact no locks are held. This is
clearly a protocol violation and with the Linux NFS client it can cause
incorrect behaviour.
If RELEASE_LOCKOWNER is sent while some other thread is still
processing a LOCK request which failed because, at the time that request
was received, the given owner held a conflicting lock, then the nfsd
thread processing that LOCK request can hold a reference (conflock) to
the lock owner that causes nfsd4_release_lockowner() to return an
incorrect error.
The Linux NFS client ignores that NFS4ERR_LOCKS_HELD error because it
never sends NFS4_RELEASE_LOCKOWNER without first releasing any locks, so
it knows that the error is impossible. It assumes the lock owner was in
fact released so it feels free to use the same lock owner identifier in
some later locking request.
When it does reuse a lock owner identifier for which a previous RELEASE
failed, it will naturally use a lock_seqid of zero. However the server,
which didn't release the lock owner, will expect a larger lock_seqid and
so will respond with NFS4ERR_BAD_SEQID.
So clearly it is harmful to allow a false positive, which testing
so_count allows.
The test is nonsense because ... well... it doesn't mean anything.
so_count is the sum of three different counts.
1/ the set of states listed on so_stateids
2/ the set of active vfs locks owned by any of those states
3/ various transient counts such as for conflicting locks.
When it is tested against '2' it is clear that one of these is the
transient reference obtained by find_lockowner_str_locked(). It is not
clear what the other one is expected to be.
In practice, the count is often 2 because there is precisely one state
on so_stateids. If there were more, this would fail.
In my testing I see two circumstances when RELEASE_LOCKOWNER is called.
In one case, CLOSE is called before RELEASE_LOCKOWNER. That results in
all the lock states being removed, and so the lockowner being discarded
(it is removed when there are no more references which usually happens
when the lock state is discarded). When nfsd4_release_lockowner() finds
that the lock owner doesn't exist, it returns success.
The other case shows an so_count of '2' and precisely one state listed
in so_stateid. It appears that the Linux client uses a separate lock
owner for each file resulting in one lock state per lock owner, so this
test on '2' is safe. For another client it might not be safe.
So this patch changes check_for_locks() to use the (newish)
find_any_file_locked() so that it doesn't take a reference on the
nfs4_file and so never calls nfsd_file_put(), and so never sleeps. With
this check is it safe to restore the use of check_for_locks() rather
than testing so_count against the mysterious '2'.

This is\nclearly a protocol violation and with the Linux NFS client it can cause\nincorrect behaviour.\n\nIf RELEASE_LOCKOWNER is sent while some other thread is still\nprocessing a LOCK request which failed because, at the time that request\nwas received, the given owner held a conflicting lock, then the nfsd\nthread processing that LOCK request can hold a reference (conflock) to\nthe lock owner that causes nfsd4_release_lockowner() to return an\nincorrect error.\n\nThe Linux NFS client ignores that NFS4ERR_LOCKS_HELD error because it\nnever sends NFS4_RELEASE_LOCKOWNER without first releasing any locks, so\nit knows that the error is impossible. It assumes the lock owner was in\nfact released so it feels free to use the same lock owner identifier in\nsome later locking request.\n\nWhen it does reuse a lock owner identifier for which a previous RELEASE\nfailed, it will naturally use a lock_seqid of zero. However the server,\nwhich didn\u0027t release the lock owner, will expect a larger lock_seqid and\nso will respond with NFS4ERR_BAD_SEQID.\n\nSo clearly it is harmful to allow a false positive, which testing\nso_count allows.\n\nThe test is nonsense because ... well... it doesn\u0027t mean anything.\n\nso_count is the sum of three different counts.\n1/ the set of states listed on so_stateids\n2/ the set of active vfs locks owned by any of those states\n3/ various transient counts such as for conflicting locks.\n\nWhen it is tested against \u00272\u0027 it is clear that one of these is the\ntransient reference obtained by find_lockowner_str_locked(). It is not\nclear what the other one is expected to be.\n\nIn practice, the count is often 2 because there is precisely one state\non so_stateids. If there were more, this would fail.\n\nIn my testing I see two circumstances when RELEASE_LOCKOWNER is called.\nIn one case, CLOSE is called before RELEASE_LOCKOWNER. That results in\nall the lock states being removed, and so the lockowner being discarded\n(it is removed when there are no more references which usually happens\nwhen the lock state is discarded). When nfsd4_release_lockowner() finds\nthat the lock owner doesn\u0027t exist, it returns success.\n\nThe other case shows an so_count of \u00272\u0027 and precisely one state listed\nin so_stateid. It appears that the Linux client uses a separate lock\nowner for each file resulting in one lock state per lock owner, so this\ntest on \u00272\u0027 is safe. For another client it might not be safe.\n\nSo this patch changes check_for_locks() to use the (newish)\nfind_any_file_locked() so that it doesn\u0027t take a reference on the\nnfs4_file and so never calls nfsd_file_put(), and so never sleeps. With\nthis check is it safe to restore the use of check_for_locks() rather\nthan testing so_count against the mysterious \u00272\u0027."

Title
mm: cachestat: fix folio read-after-free in cache walk
Summary
In the Linux kernel, the following vulnerability has been resolved:
mm: cachestat: fix folio read-after-free in cache walk
In cachestat, we access the folio from the page cache's xarray to compute
its page offset, and check for its dirty and writeback flags. However, we
do not hold a reference to the folio before performing these actions,
which means the folio can concurrently be released and reused as another
folio/page/slab.
Get around this altogether by just using xarray's existing machinery for
the folio page offsets and dirty/writeback states.
This changes behavior for tmpfs files to now always report zeroes in their
dirty and writeback counters. This is okay as tmpfs doesn't follow
conventional writeback cache behavior: its pages get "cleaned" during
swapout, after which they're no longer resident etc.
Severity
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
kprobes/x86: Use copy_from_kernel_nofault() to read from unsafe address
Read from an unsafe address with copy_from_kernel_nofault() in

the address is in text or not. Syzcaller bot found a bug and reported
the case if user specifies inaccessible data area,
arch_adjust_kprobe_addr() will cause a kernel panic.

Title
KVM: SVM: Flush pages under kvm->lock to fix UAF in svm_register_enc_region()
Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: SVM: Flush pages under kvm->lock to fix UAF in svm_register_enc_region()
Do the cache flush of converted pages in svm_register_enc_region() before
dropping kvm->lock to fix use-after-free issues where region and/or its
array of pages could be freed by a different task, e.g. if userspace has
__unregister_enc_region_locked() already queued up for the region.
Note, the "obvious" alternative of using local variables doesn't fully
resolve the bug, as region->pages is also dynamically allocated. I.e. the
region structure itself would be fine, but region->pages could be freed.
Flushing multiple pages under kvm->lock is unfortunate, but the entire
flow is a rare slow path, and the manual flush is only needed on CPUs that
lack coherency for encrypted memory.
Severity
No CVSS data available.

Title
mm: cachestat: fix two shmem bugs
Summary
In the Linux kernel, the following vulnerability has been resolved:
mm: cachestat: fix two shmem bugs
When cachestat on shmem races with swapping and invalidation, there
are two possible bugs:
1) A swapin error can have resulted in a poisoned swap entry in the
shmem inode's xarray. Calling get_shadow_from_swap_cache() on it
will result in an out-of-bounds access to swapper_spaces[].
Validate the entry with non_swap_entry() before going further.
2) When we find a valid swap entry in the shmem's inode, the shadow
entry in the swapcache might not exist yet: swap IO is still in
progress and we're before __remove_mapping; swapin, invalidation,
or swapoff have removed the shadow from swapcache after we saw the
shmem swap entry.
This will send a NULL to workingset_test_recent(). The latter
purely operates on pointer bits, so it won't crash - node 0, memcg
ID 0, eviction timestamp 0, etc. are all valid inputs - but it's a
bogus test. In theory that could result in a false "recently
evicted" count.
Such a false positive wouldn't be the end of the world. But for
code clarity and (future) robustness, be explicit about this case.
Bail on get_shadow_from_swap_cache() returning NULL.

Title
x86/coco: Require seeding RNG with RDRAND on CoCo systems
Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/coco: Require seeding RNG with RDRAND on CoCo systems
There are few uses of CoCo that don't rely on working cryptography and
hence a working RNG. Unfortunately, the CoCo threat model means that the
VM host cannot be trusted and may actively work against guests to
extract secrets or manipulate computation. Since a malicious host can
modify or observe nearly all inputs to guests, the only remaining source
of entropy for CoCo guests is RDRAND.
If RDRAND is broken -- due to CPU hardware fault -- the RNG as a whole
is meant to gracefully continue on gathering entropy from other sources,
but since there aren't other sources on CoCo, this is catastrophic.
This is mostly a concern at boot time when initially seeding the RNG, as
after that the consequences of a broken RDRAND are much more
theoretical.
So, try at boot to seed the RNG using 256 bits of RDRAND output. If this
fails, panic(). This will also trigger if the system is booted without
RDRAND, as RDRAND is essential for a safe CoCo boot.
Add this deliberately to be "just a CoCo x86 driver feature" and not
part of the RNG itself. Many device drivers and platforms have some
desire to contribute something to the RNG, and add_device_randomness()
is specifically meant for this purpose.
Any driver can call it with seed data of any quality, or even garbage
quality, and it can only possibly make the quality of the RNG better or
have no effect, but can never make it worse.
Rather than trying to build something into the core of the RNG, consider
the particular CoCo issue just a CoCo issue, and therefore separate it
all out into driver (well, arch/platform) code.
