powerpc/irq: Fix missing r2 clobber in PCREL inline assembly
In CONFIG_PPC_KERNEL_PCREL mode, r2 is no longer reserved for the TOC
pointer and is available as a caller-saved register [0].
Both call_do_irq() and call_do_softirq() use inline assembly to call
functions with stack switching, but fail to list r2 in their clobber
lists. This causes the compiler to assume r2 is preserved across these
calls, leading to register corruption when the called functions
(__do_irq and __do_softirq) clobber r2.
As a result of this kernel crash during interrupt handling is seen and
the kernel fails to boot:
BUG: Unable to handle kernel data access on write at 0xc000000404697638
Faulting instruction address: 0xc0000000000181ec
Oops: Kernel access of bad area, sig: 11 [#1]
NIP [c0000000000181ec] __do_IRQ+0x6c/0xc0
With older GCC, the compiler would conservatively allocate
callee-saved registers (like r31) for values spanning function calls,
accidentally avoiding the bug:
<__do_IRQ>:
00 00 00 60 nop
a6 02 08 7c mflr r0
f8 ff e1 fb std r31,-8(r1)
f0 ff c1 fb std r30,-16(r1)
2d 03 10 06 pla r31,53297316
...
3d e8 ff 4b bl c0000000000165ac <__do_irq>

40 00 21 38 addi r1,r1,64
2a f9 aa 7f stdx r29,r10,r31
With newer GCC 14, the compiler uses r2 for such values, exposing the
missing clobber specification:
<__do_IRQ>:
00 00 00 60 nop
a6 02 08 7c mflr r0
f0 ff c1 fb std r30,-16(r1)
f8 ff e1 fb std r31,-8(r1)
29 02 10 06 pla r2,36252592 # c0000000022aadc0 <__irq_regs>
...
85 dc ff 4b bl c000000000015ee0 <__do_irq>
00 00 21 e8 ld r1,0(r1)
28 00 2d e9 ld r9,40(r13)
30 00 21 38 addi r1,r1,48
2a 11 c9 7f stdx r30,r9,r2
Fix this by adding r2 to the clobber list for both call_do_irq() and
call_do_softirq() when CONFIG_PPC_KERNEL_PCREL is enabled.

| In the Linux kernel, the following vulnerability has been resolved:
powerpc/xive: propagate IPI init errors to prevent use-after-free
When xive_init_ipis() fails (e.g. irq_domain_alloc_irqs() fails),
the error path frees the global xive_ipis array. However,
xive_smp_probe() previously ignored this failure and proceeded to
call xive_setup_cpu_ipi(), which dereferences the already-freed
xive_ipis pointer -- a use-after-free.
Now that xive_smp_probe() returns int (previous patch), propagate
the error from xive_init_ipis() and xive_setup_cpu_ipi() through
xive_smp_probe(). Check the return value in both pnv_smp_probe()
and pSeries_smp_probe() so that IPI setup is aborted cleanly on
failure, avoiding the use-after-free. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/efa: Fix PBL chunk length computation
On register MR, when creating the PBL, if it's an indirect PBL we create
a chunk list to hold the PBL pages pointers. Each chunk is 4KB in size
and can hold 510 addresses (EFA_PTRS_PER_CHUNK) and has a 12-byte
control buffer at the end of it holding the next chunk's pointer and its
length.
If the PBL number of pages is a multiple of EFA_PTRS_PER_CHUNK, the
calculated last chunk length is wrongly computed as 0, even though that
chunk is fully populated with 510 real page pointers. This wrong length
is used both to DMA map the chunk and is propagated to the device,
causing the device to see the chunk as empty and reject the memory
registration.
Fix the calculation so it will be performed only if the number of pages
isn't a multiple of EFA_PTRS_PER_CHUNK, if it is, its already handled in
the above loop correctly.
Also prevent out-of-bounds reach in the chunks array in such scenario. |

PCI/pwrctrl: tc9563: Fix parsing the integrated Ethernet MAC Endpoint node
DSP3 has an integrated Ethernet MAC Endpoint which has its own set of
config registers for configuring settings such as ASPM. The Endpoint device
has two physical functions and those two functions share the same settings.
Parse the Endpoint node under DSP3 instead of parsing both functions. The
existing parsing logic also has one OOB issue as parsing both functions
will result in accessing past the tc9563_pwrctrl->cfg array. |
| In the Linux kernel, the following vulnerability has been resolved:
remoteproc: qcom_wcnss: Fix handling the lack of PD regulators in v3
The changes introduced to handle single power domain platforms have
swapped the info pointer increment from num_pd_vregs to num_pds, which
would shift the info pointer past the end of the array for pronto-v3,
which does not list power domain regulators in vregs.
This showed up as a difference between GCC- and LLVM-compiled kernels
on SDM632 devices, where only with LLVM one would get the
"regulator request with no identifier" error, because the out-of-bounds
memory ended up being zeroed. Fix by skipping the increment when there
are more power domains than regulators. |
| In the Linux kernel, the following vulnerability has been resolved:
pinctrl: bcm2835: Don't remove an unregistered GPIO chip
If the devm_pinctrl_register() function fails,
bcm2835_pinctrl_probe() calls gpiochip_remove()
before gpiochip_add_data() has registered the GPIO chip.
This means that upon failure the gpio_chip.gpiodev
is NULL resulting in a null pointer dereference
inside the gpiochip_remove() function.
Remove the unnecessary function call to gpiochip_remove().
No GPIO cleanup is required because the GPIO chip
has not yet been registered. Without this change there
is potential for a kernel panic upon registration failure |
| In the Linux kernel, the following vulnerability has been resolved:
staging: octeon: add missing tasklet_kill in cvm_oct_tx_shutdown
The TX cleanup tasklet can be scheduled by the watchdog IRQ handler
to execute cvm_oct_tx_do_cleanup. There can be a pending tasklet in
the queue which might run after the cvm_oct_remove() frees net_device
structures, causing a use-after-free in cvm_oct_tx_do_cleanup() as it
iterates cvm_oct_device[] which is an array of netdevice pointers.
Add tasklet_kill() after free_irq() to ensure the tasklet is no longer
scheduled or running before teardown proceeds. |

i3c: master: Fix device_register() error path
When device_register() fails in i3c_master_register_new_i3c_devs(),
put_device() is called to drop the reference taken by
device_register(). That drops the last reference, so the device's
release callback i3c_device_release() runs and frees the i3c_device.
Two problems follow from that:
i3c_device_release() does WARN_ON(i3cdev->desc), so it warns because
desc->dev->desc still points back at the descriptor. Clear it before
calling put_device().
After put_device() frees the i3c_device, desc->dev is left pointing at
freed memory, so clear desc->dev as well. That prevents, for example,
i3c_master_unregister_i3c_devs() seeing desc->dev as non-NULL and
dereferencing it. |
| In the Linux kernel, the following vulnerability has been resolved:
btrfs: restore active device pointers after failed sprout
btrfs_init_new_device() switches latest_dev and possibly s_bdev from the
seed device to the new sprout device before creating the first writable
chunks.
If chunk creation or the subsequent sprout setup fails, the error path
releases the new device without switching those pointers back.
btrfs_show_devname() can then dereference the freed latest_dev and crash.
Restore the active device pointers to the latest seed device before
removing and releasing the failed sprout device. |

netfilter: nfnetlink_log: cope with concurrent instance destruction
Instances are refcounted. However, only memory release happens on the
1 -> 0 transition; the unlink from hashes can occur with any refcount.
Uncooperative userspace can force a situation where a queue is pending
for destruction from netlink event while a different socket with same
portid processes an UNBIND request.
With right timing, this will unhash the instance again:
Oops: general protection fault, [..]

| In the Linux kernel, the following vulnerability has been resolved:
af_unix: Update last skb marker in manage_oob().
Fahad Alharbi reported that blocking recv(MSG_PEEK) could hog CPU
due to OOB skb.
In the following cases, manage_oob() skips OOB skb(s) and returns
NULL for the last recv(MSG_PEEK):
socketpair(AF_UNIX, SOCK_STREAM, 0, sk);
1) skb -> OOB skb -> NULL
send(sk[0], "ab", 2, MSG_OOB);
recv(sk[1], buf, 0, MSG_PEEK);
2) skb -> consumed OOB skb -> NULL
send(sk[0], "ab", 2, MSG_OOB);
recv(sk[1], buf, 1, MSG_OOB);
recv(sk[1], buf, 0, MSG_PEEK);
3) consumed OOB skb -> OOB skb -> NULL
send(sk[0], "a", 1, MSG_OOB);
recv(sk[1], buf, 0, MSG_OOB);
send(sk[0], "b", 1, MSG_OOB);
recv(sk[1], buf, 1, MSG_PEEK);
Then, @copied is 0 in unix_stream_read_generic() (zero-length buffer,
or non-OOB skb is not yet consumed), and unix_stream_data_wait() is
called.
However, it returns immediately because @last is not updated in
unix_stream_read_generic(), and the thread busy-waits for a new skb.
Let's update @last in manage_oob().
For MSG_PEEK, @last is updated with the skipped OOB, and for the
non-peek case, @last matches the returned value (when !copied)
because OOB is unlinked.
Note that manage_oob() is inlined and no stack canary is added. |

Bluetooth: btintel_pcie: validate packet_len before skb_put_data
btintel_pcie_submit_rx_work() reads packet_len from rfh_hdr without
checking if it exceeds the RX buffer size. An oversized packet_len
can lead to an out-of-bounds read in skb_put_data().
Validate packet_len to ensure it is non-zero and does not exceed
BTINTEL_PCIE_BUFFER_SIZE - sizeof(*rfh_hdr), logging an error when
invalid.
This issue was reported by Claude Mythos. It can be simulated either by
using customized firmware configured to return an invalid packet_len or
by modifying rfh_hdr->packet_len in the driver before calling
btintel_pcie_submit_rx_work(). |

| In the Linux kernel, the following vulnerability has been resolved:
drm/pagemap: dma-unmap pages before handling migration errors
drm_pagemap_migrate_unmap_pages() relies on the pages array to determine
which pages require DMA unmapping. However,
drm_pagemap_migration_unlock_put_pages() clears the array as part of its
cleanup, leaving drm_pagemap_migrate_unmap_pages() with no valid page
information if it is called afterward.
Call drm_pagemap_migrate_unmap_pages() before
drm_pagemap_migration_unlock_put_pages() so the pages array remains
valid during DMA unmapping. |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_conntrack: use get_unaligned_be32() in tcp_sack()
The timestamp-only fast path dereferences the option stream as
*(__be32 *)ptr, which assumes 4-byte alignment that the TCP option
stream does not guarantee. Use get_unaligned_be32() instead, which
reads the value safely and already returns host byte order, so the
htonl() on the comparison constant can be dropped.
This matches the existing get_unaligned_be32() use later in the same
function. |

| Docmost is open-source collaborative wiki and documentation software. Prior to 0.90.1, an authenticated workspace ADMIN can use the workspace invitation flow to invite an external email address with the OWNER role because the role ceiling does not prevent ADMIN users from granting privileges above their own. When the invitation is accepted, the new account receives OWNER-level permissions, allowing the ADMIN to create a backdoor OWNER account or promote a colluding external user to the workspace's highest privilege level. This issue is fixed in version 0.90.1. |
