| In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211_hwsim: drop short frames
While technically some control frames like ACK are shorter and
end after Address 1, such frames shouldn't be forwarded through
wmediumd or similar userspace, so require the full 3-address
header to avoid accessing invalid memory if shorter frames are
passed in. |
| In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix use-after-free of nilfs_root in dirtying inodes via iput
During unmount process of nilfs2, nothing holds nilfs_root structure after
nilfs2 detaches its writer in nilfs_detach_log_writer(). Previously,
nilfs_evict_inode() could cause use-after-free read for nilfs_root if
inodes are left in "garbage_list" and released by nilfs_dispose_list at
the end of nilfs_detach_log_writer(), and this bug was fixed by commit
9b5a04ac3ad9 ("nilfs2: fix use-after-free bug of nilfs_root in
nilfs_evict_inode()").
However, it turned out that there is another possibility of UAF in the
call path where mark_inode_dirty_sync() is called from iput():
nilfs_detach_log_writer()
nilfs_dispose_list()
iput()
mark_inode_dirty_sync()
__mark_inode_dirty()
nilfs_dirty_inode()
__nilfs_mark_inode_dirty()
nilfs_load_inode_block() --> causes UAF of nilfs_root struct
This can happen after commit 0ae45f63d4ef ("vfs: add support for a
lazytime mount option"), which changed iput() to call
mark_inode_dirty_sync() on its final reference if i_state has I_DIRTY_TIME
flag and i_nlink is non-zero.
This issue appears after commit 28a65b49eb53 ("nilfs2: do not write dirty
data after degenerating to read-only") when using the syzbot reproducer,
but the issue has potentially existed before.
Fix this issue by adding a "purging flag" to the nilfs structure, setting
that flag while disposing the "garbage_list" and checking it in
__nilfs_mark_inode_dirty().
Unlike commit 9b5a04ac3ad9 ("nilfs2: fix use-after-free bug of nilfs_root
in nilfs_evict_inode()"), this patch does not rely on ns_writer to
determine whether to skip operations, so as not to break recovery on
mount. The nilfs_salvage_orphan_logs routine dirties the buffer of
salvaged data before attaching the log writer, so changing
__nilfs_mark_inode_dirty() to skip the operation when ns_writer is NULL
will cause recovery write to fail. The purpose of using the cleanup-only
flag is to allow for narrowing of such conditions. |
| AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Versions 3.13.2 and below enable an attacker to ascertain the existence of absolute path components through the path normalization logic for static files meant to prevent path traversal. If an application uses web.static() (not recommended for production deployments), it may be possible for an attacker to ascertain the existence of path components. This issue is fixed in version 3.13.3. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/mlx5: Return the firmware result upon destroying QP/RQ
Previously when destroying a QP/RQ, the result of the firmware
destruction function was ignored and upper layers weren't informed
about the failure.
Which in turn could lead to various problems since when upper layer
isn't aware of the failure it continues its operation thinking that the
related QP/RQ was successfully destroyed while it actually wasn't,
which could lead to the below kernel WARN.
Currently, we return the correct firmware destruction status to upper
layers which in case of the RQ would be mlx5_ib_destroy_wq() which
was already capable of handling RQ destruction failure or in case of
a QP to destroy_qp_common(), which now would actually warn upon qp
destruction failure.

clk: mediatek: mt8183: Add back SSPM related clocks
This reverts commit 860690a93ef23b567f781c1b631623e27190f101.
On the MT8183, the SSPM related clocks were removed claiming a lack of
usage. This however causes some issues when the driver was converted to
the new simple-probe mechanism. This mechanism allocates enough space
for all the clocks defined in the clock driver, not the highest index
in the DT binding. This leads to out-of-bound writes if their are holes
in the DT binding or the driver (due to deprecated or unimplemented
clocks). These errors can go unnoticed and cause memory corruption,
leading to crashes in unrelated areas, or nothing at all. KASAN will
detect them.
Add the SSPM related clocks back to the MT8183 clock driver to fully
implement the DT binding. The SSPM clocks are for the power management
co-processor, and should never be turned off. They are marked as such. |

drm/nouveau/disp: fix use-after-free in error handling of nouveau_connector_create
We can't simply free the connector after calling drm_connector_init on it.
We need to clean up the drm side first.
It might not fix all regressions from commit 2b5d1c29f6c4

but at least it fixes a memory corruption in error handling related to
that commit. |

Smatch report warning as follows:

In tsi148_dma_list_add(), the error path "goto err_dma" will not

then list traversal may cause UAF.
Fix by removeing it from list->entries before free(). |

fs: fix UAF/GPF bug in nilfs_mdt_destroy
In alloc_inode, inode_init_always() could return -ENOMEM if
security_inode_alloc() fails, which causes inode->i_private
uninitialized. Then nilfs_is_metadata_file_inode() returns
true and nilfs_free_inode() wrongly calls nilfs_mdt_destroy(),
which frees the uninitialized inode->i_private
and leads to crashes(e.g., UAF/GPF).
Fix this by moving security_inode_alloc just prior to
this_cpu_inc(nr_inodes) |

| AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Versions 3.13.2 and below of the Python HTTP parser may allow a request smuggling attack with the presence of non-ASCII characters. If a pure Python version of AIOHTTP is installed (i.e. without the usual C extensions) or AIOHTTP_NO_EXTENSIONS is enabled, then an attacker may be able to execute a request smuggling attack to bypass certain firewalls or proxy protections. This issue is fixed in version 3.13.3. |

| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: use RCU for hci_conn_params and iterate safely in hci_sync
hci_update_accept_list_sync iterates over hdev->pend_le_conns and
hdev->pend_le_reports, and waits for controller events in the loop body,
without holding hdev lock.
Meanwhile, these lists and the items may be modified e.g. by
le_scan_cleanup. This can invalidate the list cursor or any other item
in the list, resulting to invalid behavior (eg use-after-free).
Use RCU for the hci_conn_params action lists. Since the loop bodies in
hci_sync block and we cannot use RCU or hdev->lock for the whole loop,
copy list items first and then iterate on the copy. Only the flags field
is written from elsewhere, so READ_ONCE/WRITE_ONCE should guarantee we
read valid values.
Free params everywhere with hci_conn_params_free so the cleanup is
guaranteed to be done properly.
This fixes the following, which can be triggered e.g. by BlueZ new
mgmt-tester case "Add + Remove Device Nowait - Success", or by changing
hci_le_set_cig_params to always return false, and running iso-tester:

media: netup_unidvb: fix use-after-free at del_timer()
When Universal DVB card is detaching, netup_unidvb_dma_fini()
uses del_timer() to stop dma->timeout timer. But when timer
handler netup_unidvb_dma_timeout() is running, del_timer()
could not stop it. As a result, the use-after-free bug could
happen. The process is shown below:

The root cause of the problem is that the acpi_operand_object

Fix it by removing acpi_ut_remove_reference() in

is called to copy an internal package object into another internal
package object, when it fails, the memory of acpi_operand_object
