| In the Linux kernel, the following vulnerability has been resolved:
dm-pcache: reject option groups without values
The pcache target parses optional arguments as name/value pairs. A
table that advertises one optional argument and supplies only a
recognized option name, for example "cache_mode", reaches
parse_cache_opts() with argc == 1. The parser consumes the name,
decrements argc to zero, then calls dm_shift_arg() again for the value.
dm_shift_arg() returns NULL when no arguments remain, and the following
strcmp() dereferences that NULL pointer.
Check that each recognized option has a value before consuming it. This
keeps valid "cache_mode writeback" and "data_crc true/false" tables
unchanged while making malformed tables fail during target construction
with a precise missing-value error. |
| In the Linux kernel, the following vulnerability has been resolved:
dm-integrity: fix leaking uninitialized kernel memory
If hash size is less than device's tuple size, dm-integrity is supposed
to zero the remaining space. There was a bug in the code that zeroing
didn't work. This commit fixes it. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: elx: efct: Fix I/O leak on unsupported additional CDB
efct_dispatch_fcp_cmd() allocates an efct_io before dispatching an
unsolicited FCP command. If the command has an unsupported additional
CDB, the function returns -EIO before handing the IO to the SCSI layer.
Free the allocated IO before returning from this error path. |
| In the Linux kernel, the following vulnerability has been resolved:
Input: ims-pcu - fix use-after-free and double-free in disconnect
ims_pcu_disconnect() only intended to perform cleanup when the primary
(control) interface is unbound. However, it currently relies on the
interface class to distinguish between control and data interfaces.
A malicious device could present a data interface with the same class
as the control interface, leading to premature cleanup and potential
use-after-free or double-free.
Switch to verifying that the interface being disconnected is indeed
the control interface. |
| In the Linux kernel, the following vulnerability has been resolved:
Input: ims-pcu - fix type confusion in CDC union descriptor parsing
The driver currently trusts the bMasterInterface0 from the CDC union
descriptor without verifying that it matches the interface being
probed. This could lead to the driver overwriting the private data of
another interface.
Validate that the control interface found in the descriptor is indeed
the one we are probing. |
| In the Linux kernel, the following vulnerability has been resolved:
ieee802154: ca8210: fix pointer truncation in kfifo on 64-bit
ca8210_test_int_driver_write() and ca8210_test_int_user_read() exchange
a kmalloc'd buffer pointer through a struct kfifo, but pass a literal
'4' as the byte count to kfifo_in()/kfifo_out().
This is correct on 32-bit (pointer = 4 bytes), but on 64-bit only the
low 4 bytes of the 8-byte pointer are written into the FIFO. The reader
then reads back 4 bytes into an 8-byte local pointer variable, leaving
the upper 4 bytes uninitialized stack data. The first dereference of
the reconstructed pointer (fifo_buffer[1]) accesses an arbitrary kernel
address and generally results in an oops.
Use sizeof(fifo_buffer) so the byte count matches pointer width on every
architecture.
The driver has no architecture restriction in Kconfig, so any 64-bit
build with CONFIG_IEEE802154_CA8210_DEBUGFS=y is exposed. Issue has
been latent since the driver was added in 2017 because it is most
commonly deployed on 32-bit MCUs.
Found via a custom Coccinelle semantic patch hunting for short-byte
kfifo I/O on byte-mode kfifos used to shuttle pointers. |

| In the Linux kernel, the following vulnerability has been resolved:
irqchip/irq-riscv-imsic-early: Fix fwnode leak on state setup failure
imsic_early_acpi_init() allocates a firmware node before setting up the
IMSIC state. If imsic_setup_state() fails, the function returns without
freeing the allocated fwnode.
Free the fwnode and clear the global pointer on this error path, matching
the cleanup already done when imsic_early_probe() fails.

| In the Linux kernel, the following vulnerability has been resolved:
cpu/hotplug: Fix NULL kobject warning in cpuhp_smt_enable()
On arm64, when booting with `maxcpus` greater than the number of present
CPUs (e.g., QEMU -smp cpus=4,maxcpus=8), some CPUs are marked as 'present'
but have not yet been registered via register_cpu(). Consequently,
the per-cpu device objects for these CPUs are not yet initialized.
In cpuhp_smt_enable(), the code iterates over all present CPUs. Calling
_cpu_up() for these unregistered CPUs eventually leads to
sysfs_create_group() being called with a NULL kobject (or a kobject
without a directory), triggering the following warning in
fs/sysfs/group.c:
WARNING: fs/sysfs/group.c:137 at internal_create_group+0x41c/0x4bc, CPU#2: sh/181
[...]
Call trace:
internal_create_group+0x41c/0x4bc (P)

cpuhp_invoke_callback+0x104/0x20c
__cpuhp_invoke_callback_range+0x94/0x11c
_cpu_up+0x200/0x37c
When booting with ACPI, arm64 smp_prepare_cpus() currently sets all
enumerated CPUs as "present" regardless of their status in the MADT. This
causes issues with SMT hotplug control. For instance, with QEMU's
"-smp 4,maxcpus=8" configuration, the MADT GICC entries are populated as
follows:
1. The first four CPUs: `Enabled` set but `Online Capable` not set.
2. The remaining four CPUs: `Online Capable` set but `Enabled` not set
to support potential hot-plugging.
Fix this by:
1. When booting with ACPI, checking the ACPI_MADT_ENABLED flag in the GICC
entry before calling set_cpu_present() during SMP initialization.
2. Properly managing the present mask in acpi_map_cpu() and
acpi_unmap_cpu() to support actual CPU hotplug events, This aligns with
other architectures like x86 and LoongArch.
3. Update the arm64 CPU hotplug documentation to no longer state that all
online-capable vCPUs are marked as present by the kernel at boot time.
This ensures that only physically available or explicitly enabled CPUs
are in the present mask, keeping the SMT control logic consistent with
the actual hardware state. |
| In the Linux kernel, the following vulnerability has been resolved:
riscv: Prevent NULL pointer dereference in machine_kexec_prepare()
A NULL pointer dereference issue is noticed in riscv's
machine_kexec_prepare(), where image->segment[i].buf might be NULL and
copied unchecked.
The NULL buf comes from ima_add_kexec_buffer(), where kbuf is added by
kexec_add_buffer(), but kbuf.buffer is NULL, then it is copied without
a check in machine_kexec_prepare():
kexec_file_load
-> kimage_file_alloc_init()
-> kimage_file_prepare_segments()
-> ima_add_kexec_buffer()
-> kexec_add_buffer()
-> machine_kexec_prepare()
-> memcpy()
Address this by adding a check before the data copy attempt. |
| In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: free mlx5_st_idx_data on final dealloc
Workloads that repeatedly allocate and release mkeys carrying TPH
steering-tag hints (e.g. churning RDMA MRs) leak one
struct mlx5_st_idx_data per cycle; kmemleak flags it as unreferenced
and the kmalloc slab grows over time.
When the last reference to an ST table entry is dropped,
mlx5_st_dealloc_index() removed the entry from idx_xa but the backing
mlx5_st_idx_data allocation was never freed.
Free idx_data after the xa_erase() so the lifetime of the bookkeeping
struct matches the lifetime of the ST entry it tracks. |
| In the Linux kernel, the following vulnerability has been resolved:
mtd: virt-concat: free duplicate generated name
Every MTD registration runs mtd_virt_concat_create_join(). Once a
virtual concat has already been registered, the function builds the same
name again and takes the equal-name branch. That branch skips to the
next item without freeing the newly allocated string.
Free the temporary name before continuing. |
| In the Linux kernel, the following vulnerability has been resolved:
mmc: sdhci-esdhc-imx: disable irq during suspend to fix unhandled interrupt
When using WIFI out-of-band wakeup, an "irq xxx: nobody cared" warning
occurs. This happens because the usdhc interrupt is not disabled during
system suspend when device_may_wakeup() returns false.
The sequence of events leading to this issue:
1. System enters suspend without disabling usdhc interrupt
(because device_may_wakeup() returns false for usdhc device)
2. WIFI out-of-band wakeup triggers system resume via GPIO interrupt
3. WIFI sends a Card interrupt before usdhc has fully resumed
4. usdhc is still in runtime suspend state and cannot handle the
interrupt properly
5. The unhandled interrupt triggers "nobody cared" warning
Fix this by unconditionally disabling the usdhc interrupt during suspend
and re-enabling it during resume, regardless of the wakeup capability.
This ensures no interrupts are processed during the suspend/resume
transition. |
