| In the Linux kernel, the following vulnerability has been resolved:
kho: make sure scratch size is always aligned by CMA_MIN_ALIGNMENT_BYTES
When using scratch_scale, the scratch sizes are rounded up to
CMA_MIN_ALIGNMENT_BYTES since they will be released as MIGRATE_CMA. This
is not done when using fixed scratch sizes via command line. This can
result in user specifying a size which is not aligned, and thus kernel
releasing a pageblock that is only partially scratch.
Do the rounding up for both cases in scratch_size_update(). |
| In the Linux kernel, the following vulnerability has been resolved:
fpga: microchip-spi: fix zero header_size OOB read in mpf_ops_parse_header()
mpf_ops_parse_header() reads header_size from the bitstream at
MPF_HEADER_SIZE_OFFSET (24). When header_size is zero, the expression
*(buf + header_size - 1) reads one byte before the buffer start.
Since initial_header_size is set to 71 in mpf_ops, the fpga-mgr core
guarantees the buffer is large enough to reach MPF_HEADER_SIZE_OFFSET.
The only real gap is the zero header_size case, which cannot be
resolved by providing a larger buffer, so return -EINVAL. |
| In the Linux kernel, the following vulnerability has been resolved:
irqchip/crossbar: Use correct index in crossbar_domain_free()
crossbar_domain_free() resets the domain data and then uses the nulled
out irq_data->hwirq member as index to reset the irq_map[] entry and to
write the relevant crossbar register with a safe entry. That means it
never frees the correct index and keeps the crossbar register connection
to the source interrupt active.
If it would not reset the domain data, then this would be even worse as
irq_data->hwirq holds the source interrupt number, but both the map and
register index need the corresponding GIC SPI number and not the source
interrupt number. This might even result in an out of bounds access as
the source interrupt number can be higher than the maximal index space.
Fix this by using the GIC SPI index from the parent domain's irq_data. |
| In the Linux kernel, the following vulnerability has been resolved:
tpm: tpm_tis_spi: Use wait_woken() in wait_for_tmp_stat()
wait_event_interruptible_timeout() evaluates its condition after setting
the current task state to TASK_INTERRUPTIBLE.
With CONFIG_DEBUG_ATOMIC_SLEEP this triggers a warning when the IRQ wait
path is used:
tpm_tis_status()
tpm_tis_spi_read_bytes()
tpm_tis_spi_transfer_full()
spi_bus_lock()
mutex_lock()
Address this with the following measures:
1. Call wait_tpm_stat_cond() only while tasking is running.
2. Use wait_woken() to wait for changes. |
| In the Linux kernel, the following vulnerability has been resolved:
platform/x86/intel/tpmi: use cleanup helpers in mem_write()
In mem_write(), the temporary array returned by
parse_int_array_user() must be released on all exit paths.
Convert the array variable to use cleanup.h scope-based
cleanup so it is freed automatically on return.
This also moves the array declaration next to
parse_int_array_user() as required by cleanup.h usage
guidelines. |
| In the Linux kernel, the following vulnerability has been resolved:
i2c: imx: fix locked bus on SMBus block-read of 0 (atomic)
SMBus 3.1 6.5.7 allows a Block Read byte count of 0, but the atomic
(polling) path rejects it as -EPROTO. Worse, it returns without a
NACK+STOP: the next receive cycle has already started, so the target
keeps holding SDA and the bus stays stuck until a power cycle for
this i2c controller.
Reading I2DR to obtain the count likewise arms the next byte on the
count > I2C_SMBUS_BLOCK_MAX path, which also returned -EPROTO directly
and left the bus held.
Handle both: NACK the in-flight dummy byte (TXAK) and extend msgs->len so
the existing last-byte handling emits STOP; the dummy byte is discarded.
A count of 0 is a valid empty block read; a count above
I2C_SMBUS_BLOCK_MAX is still reported as -EPROTO, but only after the bus
has been released.
The interrupt-driven path has the same flaw from a later commit and is
fixed separately, as it carries a different Fixes: tag and stable range. |
| In the Linux kernel, the following vulnerability has been resolved:
nvme-apple: Prevent shared tags across queues on Apple A11
On Apple A11, tags of pending commands must be unique across the admin
and IO queues, else the firmware crashes with
"duplicate tag error for tag N", with N being the tag.
Apply the existing workaround for M1 of reserving two tags for the admin
queue to A11. |
| 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:
riscv: probes: save original sp in rethook trampoline
Reading a word from the stack in a kretprobe crashes a risc-v kernel.

In regs_get_kernel_stack_nth, regs->sp contains an arbitrary value.
arch_rethook_trampoline saves the registers from the probed function in a
struct pt_regs. sp is not saved. Instead, sp is decremented for
arch_rethook_trampoline's local stack.
Fix this crash and save the original sp along with the other registers.
Use a0 as a temporary register, it is overwritten anyway.

| 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:
net: macb: drop in-flight Tx SKBs on close
The MACB driver has since forever leaked the outgoing SKBs that
have not yet been marked as completed. They live in queue->tx_skb
which gets freed without remorse nor checking.
macb_free_consistent() gets called in a few codepaths, but only close will
trigger the added expressions. In macb_open() and macb_alloc_consistent()
failure cases, queues' tx_skb just got allocated and are empty. |
| 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:
reset: sunxi: fix memory region leak on ioremap failure
In sunxi_reset_init(), when ioremap() fails, the memory region obtained
via request_mem_region() is not released, leading to a resource leak.
Add an err_mem_region label to properly release the memory region before
freeing the data structure. |
| 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:
net/sched: cls_u32: validate offshift to prevent shift-out-of-bounds
u32_change() copies the user-provided tc_u32_sel.offshift (unsigned char,
0-255) into the kernel knode object without bounds validation. When a
packet later hits u32_classify() with TC_U32_VAROFFSET set, it evaluates
`ntohs(offmask & *data) >> offshift` where the left operand is a 16-bit
value promoted to a 32-bit int. Any offshift >= 32 is undefined behavior
per C11 6.5.7p3, triggerable by an unprivileged user via user/network
namespaces.
UBSAN: shift-out-of-bounds in net/sched/cls_u32.c:236:43
shift exponent 32 is too large for 32-bit type int
Fix this by rejecting offshift >= 16 during filter creation in
u32_change(). |

afs: Fix error code in afs_extract_vl_addrs()
The error codes on these paths are only set on the first iteration
through the loop. Set the correct error code on every iteration. |

ipvs: reload ip header after head reallocation
__ip_vs_get_out_rt() calls skb_ensure_writable() which may
reallocate skb->head. |
