Vulnerabilidades

*** Pendiente de traducción *** A vulnerability in the Dynamic Vectoring and Streaming (DVS) Engine implementation of Cisco AsyncOS Software for Cisco Secure Web Appliance could allow an unauthenticated, remote attacker to bypass the anti-malware scanner, allowing malicious archive files to be downloaded.<br /> <br /> This vulnerability is due to improper handling of certain archive files. An attacker could exploit this vulnerability by sending a crafted archive file, which should be blocked, through an affected device. A successful exploit could allow the attacker to bypass the anti-malware scanner and download malware onto an end user workstation. The downloaded malware will not automatically execute unless the end user extracts and launches the malicious file.&amp;nbsp;

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> phy: qcom-qusb2: Fix NULL pointer dereference on early suspend<br /> <br /> Enabling runtime PM before attaching the QPHY instance as driver data<br /> can lead to a NULL pointer dereference in runtime PM callbacks that<br /> expect valid driver data. There is a small window where the suspend<br /> callback may run after PM runtime enabling and before runtime forbid.<br /> This causes a sporadic crash during boot:<br /> <br /> ```<br /> Unable to handle kernel NULL pointer dereference at virtual address 00000000000000a1<br /> [...]<br /> CPU: 0 UID: 0 PID: 11 Comm: kworker/0:1 Not tainted 6.16.7+ #116 PREEMPT<br /> Workqueue: pm pm_runtime_work<br /> pstate: 20000005 (nzCv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--)<br /> pc : qusb2_phy_runtime_suspend+0x14/0x1e0 [phy_qcom_qusb2]<br /> lr : pm_generic_runtime_suspend+0x2c/0x44<br /> [...]<br /> ```<br /> <br /> Attach the QPHY instance as driver data before enabling runtime PM to<br /> prevent NULL pointer dereference in runtime PM callbacks.<br /> <br /> Reorder pm_runtime_enable() and pm_runtime_forbid() to prevent a<br /> short window where an unnecessary runtime suspend can occur.<br /> <br /> Use the devres-managed version to ensure PM runtime is symmetrically<br /> disabled during driver removal for proper cleanup.

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> iio: imu: st_lsm6dsx: fix iio_chan_spec for sensors without event detection<br /> <br /> The st_lsm6dsx_acc_channels array of struct iio_chan_spec has a non-NULL<br /> event_spec field, indicating support for IIO events. However, event<br /> detection is not supported for all sensors, and if userspace tries to<br /> configure accelerometer wakeup events on a sensor device that does not<br /> support them (e.g. LSM6DS0), st_lsm6dsx_write_event() dereferences a NULL<br /> pointer when trying to write to the wakeup register.<br /> Define an additional struct iio_chan_spec array whose members have a NULL<br /> event_spec field, and use this array instead of st_lsm6dsx_acc_channels for<br /> sensors without event detection capability.

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> btrfs: fix deadlock in wait_current_trans() due to ignored transaction type<br /> <br /> When wait_current_trans() is called during start_transaction(), it<br /> currently waits for a blocked transaction without considering whether<br /> the given transaction type actually needs to wait for that particular<br /> transaction state. The btrfs_blocked_trans_types[] array already defines<br /> which transaction types should wait for which transaction states, but<br /> this check was missing in wait_current_trans().<br /> <br /> This can lead to a deadlock scenario involving two transactions and<br /> pending ordered extents:<br /> <br /> 1. Transaction A is in TRANS_STATE_COMMIT_DOING state<br /> <br /> 2. A worker processing an ordered extent calls start_transaction()<br /> with TRANS_JOIN<br /> <br /> 3. join_transaction() returns -EBUSY because Transaction A is in<br /> TRANS_STATE_COMMIT_DOING<br /> <br /> 4. Transaction A moves to TRANS_STATE_UNBLOCKED and completes<br /> <br /> 5. A new Transaction B is created (TRANS_STATE_RUNNING)<br /> <br /> 6. The ordered extent from step 2 is added to Transaction B&amp;#39;s<br /> pending ordered extents<br /> <br /> 7. Transaction B immediately starts commit by another task and<br /> enters TRANS_STATE_COMMIT_START<br /> <br /> 8. The worker finally reaches wait_current_trans(), sees Transaction B<br /> in TRANS_STATE_COMMIT_START (a blocked state), and waits<br /> unconditionally<br /> <br /> 9. However, TRANS_JOIN should NOT wait for TRANS_STATE_COMMIT_START<br /> according to btrfs_blocked_trans_types[]<br /> <br /> 10. Transaction B is waiting for pending ordered extents to complete<br /> <br /> 11. Deadlock: Transaction B waits for ordered extent, ordered extent<br /> waits for Transaction B<br /> <br /> This can be illustrated by the following call stacks:<br /> CPU0 CPU1<br /> btrfs_finish_ordered_io()<br /> start_transaction(TRANS_JOIN)<br /> join_transaction()<br /> # -EBUSY (Transaction A is<br /> # TRANS_STATE_COMMIT_DOING)<br /> # Transaction A completes<br /> # Transaction B created<br /> # ordered extent added to<br /> # Transaction B&amp;#39;s pending list<br /> btrfs_commit_transaction()<br /> # Transaction B enters<br /> # TRANS_STATE_COMMIT_START<br /> # waiting for pending ordered<br /> # extents<br /> wait_current_trans()<br /> # waits for Transaction B<br /> # (should not wait!)<br /> <br /> Task bstore_kv_sync in btrfs_commit_transaction waiting for ordered<br /> extents:<br /> <br /> __schedule+0x2e7/0x8a0<br /> schedule+0x64/0xe0<br /> btrfs_commit_transaction+0xbf7/0xda0 [btrfs]<br /> btrfs_sync_file+0x342/0x4d0 [btrfs]<br /> __x64_sys_fdatasync+0x4b/0x80<br /> do_syscall_64+0x33/0x40<br /> entry_SYSCALL_64_after_hwframe+0x44/0xa9<br /> <br /> Task kworker in wait_current_trans waiting for transaction commit:<br /> <br /> Workqueue: btrfs-syno_nocow btrfs_work_helper [btrfs]<br /> __schedule+0x2e7/0x8a0<br /> schedule+0x64/0xe0<br /> wait_current_trans+0xb0/0x110 [btrfs]<br /> start_transaction+0x346/0x5b0 [btrfs]<br /> btrfs_finish_ordered_io.isra.0+0x49b/0x9c0 [btrfs]<br /> btrfs_work_helper+0xe8/0x350 [btrfs]<br /> process_one_work+0x1d3/0x3c0<br /> worker_thread+0x4d/0x3e0<br /> kthread+0x12d/0x150<br /> ret_from_fork+0x1f/0x30<br /> <br /> Fix this by passing the transaction type to wait_current_trans() and<br /> checking btrfs_blocked_trans_types[cur_trans-&gt;state] against the given<br /> type before deciding to wait. This ensures that transaction types which<br /> are allowed to join during certain blocked states will not unnecessarily<br /> wait and cause deadlocks.

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> phy: stm32-usphyc: Fix off by one in probe()<br /> <br /> The "index" variable is used as an index into the usbphyc-&gt;phys[] array<br /> which has usbphyc-&gt;nphys elements. So if it is equal to usbphyc-&gt;nphys<br /> then it is one element out of bounds. The "index" comes from the<br /> device tree so it&amp;#39;s data that we trust and it&amp;#39;s unlikely to be wrong,<br /> however it&amp;#39;s obviously still worth fixing the bug. Change the &gt; to &gt;=.
