| In the Linux kernel, the following vulnerability has been resolved:
mm/filemap: fix filemap_get_folios_contig THP panic
Patch series "memfd-pin huge page fixes".
Fix multiple bugs that occur when using memfd_pin_folios with hugetlb
pages and THP. The hugetlb bugs only bite when the page is not yet
faulted in when memfd_pin_folios is called. The THP bug bites when the
starting offset passed to memfd_pin_folios is not huge page aligned. See
the commit messages for details.
This patch (of 5):
memfd_pin_folios on memory backed by THP panics if the requested start
offset is not huge page aligned:
BUG: kernel NULL pointer dereference, address: 0000000000000036
RIP: 0010:filemap_get_folios_contig+0xdf/0x290
RSP: 0018:ffffc9002092fbe8 EFLAGS: 00010202
RAX: 0000000000000002 RBX: 0000000000000002 RCX: 0000000000000002
The fault occurs here, because xas_load returns a folio with value 2:
filemap_get_folios_contig()
for (folio = xas_load(&xas); folio && xas.xa_index <= end;
folio = xas_next(&xas)) {
...
if (!folio_try_get(folio)) <-- BOOM
"2" is an xarray sibling entry. We get it because memfd_pin_folios does
not round the indices passed to filemap_get_folios_contig to huge page
boundaries for THP, so we load from the middle of a huge page range see a
sibling. (It does round for hugetlbfs, at the is_file_hugepages test).
To fix, if the folio is a sibling, then return the next index as the
starting point for the next call to filemap_get_folios_contig. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: mvm: set the cipher for secured NDP ranging
The cipher pointer is not set, but is derefereced trying to set its
content, which leads to a NULL pointer dereference.
Fix it by pointing to the cipher parameter before dereferencing. |
| In the Linux kernel, the following vulnerability has been resolved:
media: mediatek: vcodec: Fix H264 stateless decoder smatch warning
Fix a smatch static checker warning on vdec_h264_req_if.c.
Which leads to a kernel crash when fb is NULL. |

With the latest Linux-6.11-rc3, the below NULL pointer crash is observed
when SBI PMU snapshot is enabled for the guest and the guest is forcefully
powered-off.

Clearly, the kvm_vcpu_write_guest() function is crashing because it is
being called from kvm_pmu_clear_snapshot_area() upon guest tear down.
To address the above issue, simplify the kvm_pmu_clear_snapshot_area() to
not zero-out PMU snapshot area from kvm_pmu_clear_snapshot_area() because
the guest is anyway being tore down.
The kvm_pmu_clear_snapshot_area() is also called when guest changes
PMU snapshot area of a VCPU but even in this case the previous PMU
snaphsot area must not be zeroed-out because the guest might have
reclaimed the pervious PMU snapshot area for some other purpose. |

netkit: Assign missing bpf_net_context
During the introduction of struct bpf_net_context handling for
XDP-redirect, the netkit driver has been missed, which also requires it
because NETKIT_REDIRECT invokes skb_do_redirect() which is accessing the
per-CPU variables. Otherwise we see the following crash:

IB/mlx5: Fix UMR pd cleanup on error flow of driver init
The cited commit moves the pd allocation from function
mlx5r_umr_resource_cleanup() to a new function mlx5r_umr_cleanup().
So the fix in commit [1] is broken. In error flow, will hit panic [2].
Fix it by checking pd pointer to avoid panic if it is NULL;

| In the Linux kernel, the following vulnerability has been resolved:
f2fs: check discard support for conventional zones
As the helper function f2fs_bdev_support_discard() shows, f2fs checks if
the target block devices support discard by calling
bdev_max_discard_sectors() and bdev_is_zoned(). This check works well
for most cases, but it does not work for conventional zones on zoned
block devices. F2fs assumes that zoned block devices support discard,
and calls __submit_discard_cmd(). When __submit_discard_cmd() is called
for sequential write required zones, it works fine since
__submit_discard_cmd() issues zone reset commands instead of discard
commands. However, when __submit_discard_cmd() is called for
conventional zones, __blkdev_issue_discard() is called even when the
devices do not support discard.
The inappropriate __blkdev_issue_discard() call was not a problem before
the commit 30f1e7241422 ("block: move discard checks into the ioctl
handler") because __blkdev_issue_discard() checked if the target devices
support discard or not. If not, it returned EOPNOTSUPP. After the
commit, __blkdev_issue_discard() no longer checks it. It always returns
zero and sets NULL to the given bio pointer. This NULL pointer triggers
f2fs_bug_on() in __submit_discard_cmd(). The BUG is recreated with the
commands below at the umount step, where /dev/nullb0 is a zoned null_blk
with 5GB total size, 128MB zone size and 10 conventional zones.
$ mkfs.f2fs -f -m /dev/nullb0
$ mount /dev/nullb0 /mnt
$ for ((i=0;i<5;i++)); do dd if=/dev/zero of=/mnt/test bs=65536 count=1600 conv=fsync; done
$ umount /mnt
To fix the BUG, avoid the inappropriate __blkdev_issue_discard() call.
When discard is requested for conventional zones, check if the device
supports discard or not. If not, return EOPNOTSUPP. |

wifi: mt76: mt7921: fix NULL pointer access in mt7921_ipv6_addr_change

net: phy: dp83822: Fix NULL pointer dereference on DP83825 devices
The probe() function is only used for DP83822 and DP83826 PHY,
leaving the private data pointer uninitialized for the DP83825 models
which causes a NULL pointer dereference in the recently introduced/changed
functions dp8382x_config_init() and dp83822_set_wol().
Add the dp8382x_probe() function, so all PHY models will have a valid
private data pointer to fix this issue and also prevent similar issues
in the future. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Avoid race between dcn10_set_drr() and dc_state_destruct()
dc_state_destruct() nulls the resource context of the DC state. The pipe
context passed to dcn10_set_drr() is a member of this resource context.
If dc_state_destruct() is called parallel to the IRQ processing (which
calls dcn10_set_drr() at some point), we can end up using already nulled
function callback fields of struct stream_resource.
The logic in dcn10_set_drr() already tries to avoid this, by checking tg
against NULL. But if the nulling happens exactly after the NULL check and
before the next access, then we get a race.
Avoid this by copying tg first to a local variable, and then use this
variable for all the operations. This should work, as long as nobody
frees the resource pool where the timing generators live.

ASoC: Intel: Boards: Fix NULL pointer deref in BYT/CHT boards harder
Since commit 13f58267cda3 ("ASoC: soc.h: don't create dummy Component
via COMP_DUMMY()") dummy codecs declared like this:
SND_SOC_DAILINK_DEF(dummy,
DAILINK_COMP_ARRAY(COMP_DUMMY()));
expand to:
static struct snd_soc_dai_link_component dummy[] = {
};
Which means that dummy is a zero sized array and thus dais[i].codecs should
not be dereferenced *at all* since it points to the address of the next
variable stored in the data section as the "dummy" variable has an address
but no size, so even dereferencing dais[0] is already an out of bounds
array reference.
Which means that the if (dais[i].codecs->name) check added in
commit 7d99a70b6595 ("ASoC: Intel: Boards: Fix NULL pointer deref
in BYT/CHT boards") relies on that the part of the next variable which
the name member maps to just happens to be NULL.
Which apparently so far it usually is, except when it isn't
and then it results in crashes like this one:

thread making it "exit" before it actually exits.

| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Check UnboundedRequestEnabled's value
CalculateSwathAndDETConfiguration_params_st's UnboundedRequestEnabled
is a pointer (i.e. dml_bool_t *UnboundedRequestEnabled), and thus
if (p->UnboundedRequestEnabled) checks its address, not bool value.
This fixes 1 REVERSE_INULL issue reported by Coverity. |
| In the Linux kernel, the following vulnerability has been resolved:
spi: intel: Add check devm_kasprintf() returned value
intel_spi_populate_chip() use devm_kasprintf() to set pdata->name.
This can return a NULL pointer on failure but this returned value
is not checked. |
| In the Linux kernel, the following vulnerability has been resolved:
hwmon: (hp-wmi-sensors) Check if WMI event data exists
The BIOS can choose to return no event data in response to a
WMI event, so the ACPI object passed to the WMI notify handler
can be NULL.
Check for such a situation and ignore the event in such a case. |
