When calling hfsplus_bmap_alloc to allocate a free node, this function
first retrieves the bitmap from header node and map node using node->page
together with the offset and length from hfs_brec_lenoff
```
len = hfs_brec_lenoff(node, 2, &off16);
off = off16;
off += node->page_offset;
pagep = node->page + (off >> PAGE_SHIFT);
data = kmap_local_page(*pagep);
```
However, if the retrieved offset or length is invalid(i.e. exceeds
node_size), the code may end up accessing pages outside the allocated
range for this node.
This patch adds proper validation of both offset and length before use,
preventing out-of-bounds page access. Move is_bnode_offset_valid and
check_and_correct_requested_length to hfsplus_fs.h, as they may be
required by other functions. |
| In the Linux kernel, the following vulnerability has been resolved:
slab: Avoid race on slab->obj_exts in alloc_slab_obj_exts
If two competing threads enter alloc_slab_obj_exts() and one of them
fails to allocate the object extension vector, it might override the
valid slab->obj_exts allocated by the other thread with
OBJEXTS_ALLOC_FAIL. This will cause the thread that lost this race and
expects a valid pointer to dereference a NULL pointer later on.
Update slab->obj_exts atomically using cmpxchg() to avoid
slab->obj_exts overrides by racing threads.
Thanks for Vlastimil and Suren's help with debugging. |

| In the Linux kernel, the following vulnerability has been resolved:
platform/x86: int3472: Fix double free of GPIO device during unregister
regulator_unregister() already frees the associated GPIO device. On
ThinkPad X9 (Lunar Lake), this causes a double free issue that leads to
random failures when other drivers (typically Intel THC) attempt to
allocate interrupts. The root cause is that the reference count of the
pinctrl_intel_platform module unexpectedly drops to zero when this
driver defers its probe.
This behavior can also be reproduced by unloading the module directly.
Fix the issue by removing the redundant release of the GPIO device
during regulator unregistration. |
| The Datadog Agent collects events and metrics from hosts and sends them to Datadog. A vulnerability within the Datadog Linux Host Agent versions 7.65.0 through 7.70.2 exists due to insufficient permissions being set on the `opt/datadog-agent/python-scripts/__pycache__` directory during installation. Code in this directory is only run by the Agent during Agent install/upgrades. This could allow an attacker with local access to modify files in this directory, which would then subsequently be run when the Agent is upgraded, resulting in local privilege escalation. This issue requires local access to the host and a valid low privilege account to be vulnerable. Note that this vulnerability only impacts the Linux Host Agent. Other variations of the Agent including the container, kubernetes, windows host and other agents are not impacted. Version 7.71.0 contains a patch for the issue. |
| In the Linux kernel, the following vulnerability has been resolved:
mm/damon/vaddr: do not repeat pte_offset_map_lock() until success
DAMON's virtual address space operation set implementation (vaddr) calls
pte_offset_map_lock() inside the page table walk callback function. This
is for reading and writing page table accessed bits. If
pte_offset_map_lock() fails, it retries by returning the page table walk
callback function with ACTION_AGAIN.
pte_offset_map_lock() can continuously fail if the target is a pmd
migration entry, though. Hence it could cause an infinite page table walk
if the migration cannot be done until the page table walk is finished.
This indeed caused a soft lockup when CPU hotplugging and DAMON were
running in parallel.
Avoid the infinite loop by simply not retrying the page table walk. DAMON
is promising only a best-effort accuracy, so missing access to such pages
is no problem. |
| In the Linux kernel, the following vulnerability has been resolved:
hwmon: (cgbc-hwmon) Add missing NULL check after devm_kzalloc()
The driver allocates memory for sensor data using devm_kzalloc(), but
did not check if the allocation succeeded. In case of memory allocation
failure, dereferencing the NULL pointer would lead to a kernel crash.
Add a NULL pointer check and return -ENOMEM to handle allocation failure
properly. |
| In the Linux kernel, the following vulnerability has been resolved:
mm/damon/core: fix potential memory leak by cleaning ops_filter in damon_destroy_scheme
Currently, damon_destroy_scheme() only cleans up the filter list but
leaves ops_filter untouched, which could lead to memory leaks when a
scheme is destroyed.
This patch ensures both filter and ops_filter are properly freed in
damon_destroy_scheme(), preventing potential memory leaks. |
| In the Linux kernel, the following vulnerability has been resolved:
rv: Fully convert enabled_monitors to use list_head as iterator
The callbacks in enabled_monitors_seq_ops are inconsistent. Some treat the
iterator as struct rv_monitor *, while others treat the iterator as struct
list_head *.
This causes a wrong type cast and crashes the system as reported by Nathan.
Convert everything to use struct list_head * as iterator. This also makes
enabled_monitors consistent with available_monitors. |
| In the Linux kernel, the following vulnerability has been resolved:
net: phy: micrel: always set shared->phydev for LAN8814
Currently, during the LAN8814 PTP probe shared->phydev is only set if PTP
clock gets actually set, otherwise the function will return before setting
it.
This is an issue as shared->phydev is unconditionally being used when IRQ
is being handled, especially in lan8814_gpio_process_cap and since it was
not set it will cause a NULL pointer exception and crash the kernel.
So, simply always set shared->phydev to avoid the NULL pointer exception. |
| In the Linux kernel, the following vulnerability has been resolved:
nios2: ensure that memblock.current_limit is set when setting pfn limits
On nios2, with CONFIG_FLATMEM set, the kernel relies on
memblock_get_current_limit() to determine the limits of mem_map, in
particular for max_low_pfn.
Unfortunately, memblock.current_limit is only default initialized to
MEMBLOCK_ALLOC_ANYWHERE at this point of the bootup, potentially leading
to situations where max_low_pfn can erroneously exceed the value of
max_pfn and, thus, the valid range of available DRAM.
This can in turn cause kernel-level paging failures, e.g.:
[ 76.900000] Unable to handle kernel paging request at virtual address 20303000
[ 76.900000] ea = c0080890, ra = c000462c, cause = 14
[ 76.900000] Kernel panic - not syncing: Oops
[ 76.900000] ---[ end Kernel panic - not syncing: Oops ]---
This patch fixes this by pre-calculating memblock.current_limit
based on the upper limits of the available memory ranges via
adjust_lowmem_bounds, a simplified version of the equivalent
implementation within the arm architecture. |
| In the Linux kernel, the following vulnerability has been resolved:
sched_ext: Fix scx_enable() crash on helper kthread creation failure
A crash was observed when the sched_ext selftests runner was
terminated with Ctrl+\ while test 15 was running:
NIP [c00000000028fa58] scx_enable.constprop.0+0x358/0x12b0

kthread_run_worker() returns an ERR_PTR() on failure rather than NULL,
but the current code in scx_alloc_and_add_sched() only checks for a NULL
helper. Incase of failure on SIGQUIT, the error is not handled in
scx_alloc_and_add_sched() and scx_enable() ends up dereferencing an
error pointer.
Error handling is fixed in scx_alloc_and_add_sched() to propagate
PTR_ERR() into ret, so that scx_enable() jumps to the existing error
path, avoiding random dereference on failure. |
| In the Linux kernel before 4.8, usb_parse_endpoint in drivers/usb/core/config.c does not validate the wMaxPacketSize field of an endpoint descriptor. NOTE: This vulnerability only affects products that are no longer supported by the supplier. |
| In the Linux kernel, the following vulnerability has been resolved:
coresight: ETR: Fix ETR buffer use-after-free issue
When ETR is enabled as CS_MODE_SYSFS, if the buffer size is changed
and enabled again, currently sysfs_buf will point to the newly
allocated memory(buf_new) and free the old memory(buf_old). But the
etr_buf that is being used by the ETR remains pointed to buf_old, not
updated to buf_new. In this case, it will result in a memory
use-after-free issue.
Fix this by checking ETR's mode before updating and releasing buf_old,
if the mode is CS_MODE_SYSFS, then skip updating and releasing it. |
| The llama-index-core package, up to version 0.12.44, contains a vulnerability in the `get_cache_dir()` function where a predictable, hardcoded directory path `/tmp/llama_index` is used on Linux systems without proper security controls. This vulnerability allows attackers on multi-user systems to steal proprietary models, poison cached embeddings, or conduct symlink attacks. The issue affects all Linux deployments where multiple users share the same system. The vulnerability is classified under CWE-379, CWE-377, and CWE-367, indicating insecure temporary file creation and potential race conditions. |
| In the Linux kernel, the following vulnerability has been resolved:
net: stmmac: Correctly handle Rx checksum offload errors
The stmmac_rx function would previously set skb->ip_summed to
CHECKSUM_UNNECESSARY if hardware checksum offload (CoE) was enabled
and the packet was of a known IP ethertype.
However, this logic failed to check if the hardware had actually
reported a checksum error. The hardware status, indicating a header or
payload checksum failure, was being ignored at this stage. This could
cause corrupt packets to be passed up the network stack as valid.
This patch corrects the logic by checking the `csum_none` status flag,
which is set when the hardware reports a checksum error. If this flag
is set, skb->ip_summed is now correctly set to CHECKSUM_NONE,
ensuring the kernel's network stack will perform its own validation and
properly handle the corrupt packet. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: Intel: avs: Do not share the name pointer between components
By sharing 'name' directly, tearing down components may lead to
use-after-free errors. Duplicate the name to avoid that.
At the same time, update the order of operations - since commit
cee28113db17 ("ASoC: dmaengine_pcm: Allow passing component name via
config") the framework does not override component->name if set before
invoking the initializer. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: validate userq buffer virtual address and size
It needs to validate the userq object virtual address to
determine whether it is residented in a valid vm mapping. |
| In the Linux kernel, the following vulnerability has been resolved:
bnxt_en: Shutdown FW DMA in bnxt_shutdown()
The netif_close() call in bnxt_shutdown() only stops packet DMA. There
may be FW DMA for trace logging (recently added) that will continue. If
we kexec to a new kernel, the DMA will corrupt memory in the new kernel.
Add bnxt_hwrm_func_drv_unrgtr() to unregister the driver from the FW.
This will stop the FW DMA. In case the call fails, call pcie_flr() to
reset the function and stop the DMA. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Fix mmap write lock not release
If mmap write lock is taken while draining retry fault, mmap write lock
is not released because svm_range_restore_pages calls mmap_read_unlock
then returns. This causes deadlock and system hangs later because mmap
read or write lock cannot be taken.
Downgrade mmap write lock to read lock if draining retry fault fix this
bug. |
