| In the Linux kernel, the following vulnerability has been resolved:
sfc: Don't invoke xdp_do_flush() from netpoll.
Yury reported a crash in the sfc driver originated from
netpoll_send_udp(). The netconsole sends a message and then netpoll
invokes the driver's NAPI function with a budget of zero. It is
dedicated to allow driver to free TX resources, that it may have used
while sending the packet.
In the netpoll case the driver invokes xdp_do_flush() unconditionally,
leading to crash because bpf_net_context was never assigned.
Invoke xdp_do_flush() only if budget is not zero. |
| In the Linux kernel, the following vulnerability has been resolved:
net: netconsole: fix wrong warning
A warning is triggered when there is insufficient space in the buffer
for userdata. However, this is not an issue since userdata will be sent
in the next iteration.
Current warning message:
------------[ cut here ]------------
WARNING: CPU: 13 PID: 3013042 at drivers/net/netconsole.c:1122 write_ext_msg+0x3b6/0x3d0
? write_ext_msg+0x3b6/0x3d0
console_flush_all+0x1e9/0x330
The code incorrectly issues a warning when this_chunk is zero, which is
a valid scenario. The warning should only be triggered when this_chunk
is negative. |
| In the Linux kernel, the following vulnerability has been resolved:
dm vdo: don't refer to dedupe_context after releasing it
Clear the dedupe_context pointer in a data_vio whenever ownership of
the context is lost, so that vdo can't examine it accidentally. |
| In the Linux kernel, the following vulnerability has been resolved:
ublk: don't allow user copy for unprivileged device
UBLK_F_USER_COPY requires userspace to call write() on ublk char
device for filling request buffer, and unprivileged device can't
be trusted.
So don't allow user copy for unprivileged device. |
| In the Linux kernel, the following vulnerability has been resolved:
io_uring/sqpoll: ensure task state is TASK_RUNNING when running task_work
When the sqpoll is exiting and cancels pending work items, it may need
to run task_work. If this happens from within io_uring_cancel_generic(),
then it may be under waiting for the io_uring_task waitqueue. This
results in the below splat from the scheduler, as the ring mutex may be
attempted grabbed while in a TASK_INTERRUPTIBLE state.
Ensure that the task state is set appropriately for that, just like what
is done for the other cases in io_run_task_work().

xhci: tegra: fix checked USB2 port number
If USB virtualizatoin is enabled, USB2 ports are shared between all
Virtual Functions. The USB2 port number owned by an USB2 root hub in
a Virtual Function may be less than total USB2 phy number supported
by the Tegra XUSB controller.
Using total USB2 phy number as port number to check all PORTSC values
would cause invalid memory access.

ptp: vmclock: Add .owner to vmclock_miscdev_fops
Without the .owner field, the module can be unloaded while /dev/vmclock0
is open, leading to an oops. |
| In the Linux kernel, the following vulnerability has been resolved:
mm: clear uffd-wp PTE/PMD state on mremap()
When mremap()ing a memory region previously registered with userfaultfd as
write-protected but without UFFD_FEATURE_EVENT_REMAP, an inconsistency in
flag clearing leads to a mismatch between the vma flags (which have
uffd-wp cleared) and the pte/pmd flags (which do not have uffd-wp
cleared). This mismatch causes a subsequent mprotect(PROT_WRITE) to
trigger a warning in page_table_check_pte_flags() due to setting the pte
to writable while uffd-wp is still set.
Fix this by always explicitly clearing the uffd-wp pte/pmd flags on any
such mremap() so that the values are consistent with the existing clearing
of VM_UFFD_WP. Be careful to clear the logical flag regardless of its
physical form; a PTE bit, a swap PTE bit, or a PTE marker. Cover PTE,
huge PMD and hugetlb paths. |

wifi: rtw89: chan: fix soft lockup in rtw89_entity_recalc_mgnt_roles()
During rtw89_entity_recalc_mgnt_roles(), there is a normalizing process
which will re-order the list if an entry with target pattern is found.
And once one is found, should have aborted the list_for_each_entry. But,
`break` just aborted the inner for-loop. The outer list_for_each_entry
still continues. Normally, only the first entry will match the target
pattern, and the re-ordering will change nothing, so there won't be
soft lockup. However, in some special cases, soft lockup would happen.
Fix it by `goto fill` to break from the list_for_each_entry.
The following is a sample of kernel log for this problem.
watchdog: BUG: soft lockup - CPU#1 stuck for 26s! [wpa_supplicant:2055]

Revert "libfs: fix infinite directory reads for offset dir"
The current directory offset allocator (based on mtree_alloc_cyclic)
stores the next offset value to return in octx->next_offset. This
mechanism typically returns values that increase monotonically over
time. Eventually, though, the newly allocated offset value wraps
back to a low number (say, 2) which is smaller than other already-
allocated offset values.
Yu Kuai <yukuai3@huawei.com> reports that, after commit 64a7ce76fb90
("libfs: fix infinite directory reads for offset dir"), if a
directory's offset allocator wraps, existing entries are no longer
visible via readdir/getdents because offset_readdir() stops listing
entries once an entry's offset is larger than octx->next_offset.
These entries vanish persistently -- they can be looked up, but will
never again appear in readdir(3) output.
The reason for this is that the commit treats directory offsets as
monotonically increasing integer values rather than opaque cookies,
and introduces this comparison:
if (dentry2offset(dentry) >= last_index) {
On 64-bit platforms, the directory offset value upper bound is
2^63 - 1. Directory offsets will monotonically increase for millions
of years without wrapping.
On 32-bit platforms, however, LONG_MAX is 2^31 - 1. The allocator
can wrap after only a few weeks (at worst).
Revert commit 64a7ce76fb90 ("libfs: fix infinite directory reads for
offset dir") to prepare for a fix that can work properly on 32-bit
systems and might apply to recent LTS kernels where shmem employs
the simple_offset mechanism. |

mtd: spinand: winbond: Fix 512GW, 01GW, 01JW and 02JW ECC information
These four chips:
* W25N512GW
* W25N01GW
* W25N01JW
* W25N02JW
all require a single bit of ECC strength and thus feature an on-die
Hamming-like ECC engine. There is no point in filling a ->get_status()
callback for them because the main ECC status bytes are located in
standard places, and retrieving the number of bitflips in case of
corrected chunk is both useless and unsupported (if there are bitflips,
then there is 1 at most, so no need to query the chip for that).
Without this change, a kernel warning triggers every time a bit flips. |

RISCV platform which does not provide PCI/MSI support:
WARNING: CPU: 1 PID: 1 at drivers/pci/msi/msi.h:121 pci_msi_setup_msi_irqs+0x2c/0x32

RISCV uses hierarchical interrupt domains and correctly does not implement
the legacy fallback. The warning triggers from the legacy fallback stub.
That warning is bogus as the PCI/MSI layer knows whether a PCI/MSI parent
domain is associated with the device or not. There is a check for MSI-X,
which has a legacy assumption. But that legacy fallback assumption is only
valid when legacy support is enabled, but otherwise the check should simply
return -ENOTSUPP.
Loongarch tripped over the same problem and blindly enabled legacy support
without implementing the legacy fallbacks. There are weak implementations
which return an error, so the problem was papered over.
Correct pci_msi_domain_supports() to evaluate the legacy mode and add
the missing supported check into the MSI enable path to complete it. |

drm/nouveau/gr/gf100: Fix missing unlock in gf100_gr_chan_new()
When the call to gf100_grctx_generate() fails, unlock gr->fecs.mutex
before returning the error.
Fixes smatch warning:
drivers/gpu/drm/nouveau/nvkm/engine/gr/gf100.c:480 gf100_gr_chan_new() warn: inconsistent returns '&gr->fecs.mutex'. |
