The issue was introduced by commit 687aa0c5581b ("vsock: Fix transport_* TOCTOU") which added vsock_register_mutex locking in vsock_assign_transport() around the transport->release() call, that can call vsock_linger(). vsock_assign_transport() can be called with sk_lock held. vsock_linger() calls sk_wait_event() that temporarily releases and re-acquires sk_lock. During this window, if another thread hold vsock_register_mutex while trying to acquire sk_lock, a circular dependency is created. Fix this by releasing vsock_register_mutex before calling transport->release() and vsock_deassign_transport(). This is safe because we don't need to hold vsock_register_mutex while releasing the old transport, and we ensure the new transport won't disappear by obtaining a module reference first via try_module_get().

[REGRESSION] 6.16 fae58d0155 prevents boot of google-tomato (mt8195)

by ninelore

Hi, starting with the bisected commit fae58d0155a979a8c414bbc12db09dd4b2f910d0 ("[v2] drm/mediatek: Fix device/node reference count leaks in mtk_drm_get_all_drm_priv") on 6.16.y my chromebook codenamed google-tomato with the SoC MT8195 seems to hang while initializing drm. Kernel messages over serial show CPU stalls some minutes later. I am attaching the full kernel logs below. This issue is present in 6.16.7, however not in v6.17-rc6 This is my first time reporting a bug here. Please let me know if you need additional information.

[PATCH] drm/tegra: Fix reference count leak in tegra_dc_couple

by Miaoqian Lin

The driver_find_device() function returns a device with its reference count incremented. The caller is responsible for calling put_device() to release this reference when done. Fix this leak by adding the missing put_device() call. Found via static analysis.

[PATCH 5.10] scsi: target: target_core_configfs: Add length check to avoid buffer overflow

by Andrey Troshin

From: Wang Haoran <haoranwangsec(a)gmail.com> commit 27e06650a5eafe832a90fd2604f0c5e920857fae upstream. A buffer overflow arises from the usage of snprintf to write into the buffer "buf" in target_lu_gp_members_show function located in /drivers/target/target_core_configfs.c. This buffer is allocated with size LU_GROUP_NAME_BUF (256 bytes). snprintf(...) formats multiple strings into buf with the HBA name (hba->hba_group.cg_item), a slash character, a devicename (dev-> dev_group.cg_item) and a newline character, the total formatted string length may exceed the buffer size of 256 bytes. Since snprintf() returns the total number of bytes that would have been written (the length of %s/%sn ), this value may exceed the buffer length (256 bytes) passed to memcpy(), this will ultimately cause function memcpy reporting a buffer overflow error. An additional check of the return value of snprintf() can avoid this buffer overflow.

📞 For the fastest help, call Play Airlines customer support at 1-866-284-3022. Their agents are trained to assist with name corrections. ✍️ Did you book a flight with Play Airlines and realize your name is misspelled or needs updating? Whether it is a minor typo or a legal name change, it is essential to correct your flight details before travel to avoid problems at check-in. Fortunately, Play Airlines offers options for name changes or corrections — and we are here to guide you through the process, step by step. 📌 Why Name Corrections Matter Airlines require that the name on your ticket exactly matches the name on your government-issued ID or passport. Even a small typo can result in: ❌ Denied boarding ❌ TSA security issues ❌ Non-refundable tickets going to waste That is why it is important to act quickly if you notice an error. 👉 Pro Tip: As soon as you spot an issue with your name, call 1-866-284-3022 to fix it directly with Play Airlines. 📋 Play Airlines Name Correction Policy: The Basics Play Airlines does allow name corrections and changes, but there are specific rules based on the type and extent of the correction. ✏️ Minor Name Corrections If your correction is minor (e.g., spelling mistake, missing middle name, or nickname to legal name), it is usually easy to fix.

How to Speak to a Live Person Malaysia Airlines: Tips and Tricks

by scottgar.cia.727.69＠gmail.com

Need to talk to a real person Malaysia Airlines? Calling Malaysia Airlines directly at 📞 1-866-284-3022. Whether you are trying to make a flight change, cancel your booking, ask about baggage, or resolve a booking issue, reaching a live agent can save you time, stress, and confusion. While automated systems are useful for simple tasks, some situations just need a human touch. In this guide, we will walk you through exactly how to reach a live person, what to prepare before calling, and alternate methods if the phone lines are busy. ☎️ First Things First: Call 1-866-284-3022 The most direct and reliable way to speak with a real Malaysia Airlines representative is by calling 📞 1-866-284-3022. This is Frontier’s official customer service number and should be your go-to for: ✈️ Flight changes or cancellations 🧾 Refund or credit questions 🛄 Baggage issues 🔁 Name corrections 🛑 Check-in or boarding problems 💺 Seat selection and upgrades Pro Tip: When calling, try to do so during non-peak hours — early mornings or late evenings — to reduce your hold time. 🎧 How to Navigate the Automated Menu When you call 1-866-284-3022, you will first hear an automated system. To get through to a live person faster, follow these steps: Dial 1-866-284-3022 Wait for the automated greeting to begin Press “1” for English (or “2” for Spanish) Press “2” for existing reservations Press “0” to speak with an agent (you may need to press "0" more than once) 👉 If “0” does not work immediately, stay on the line. Sometimes the system transfers you to an agent after a brief wait without needing more input. If the lines are busy and you are placed on hold, do not hang up — wait times vary, but you will eventually reach someone. 🧾 What to Have Ready Before You Call To help the agent assist you faster, make sure you have the following details on hand: 📌 Your confirmation code or booking number 📌 The full name on the reservation 📌 Your flight date and destination 📌 Any relevant documents (ID, credit card, etc.) 📌 A notepad for writing down instructions or confirmation numbers If you are calling to fix a mistake or request a refund, be prepared to briefly explain the issue and possibly provide documentation via email upon request. ⏰ Best Times to Call 1-866-284-3022 Customer service lines can be busy, especially during: ⚠️ Holidays ⚠️ Severe weather or flight delays ⚠️ Early morning flight hours 🎯 For the best chance at a short wait, try calling during these times: 🕔 5:00 AM – 7:00 AM (EST) 🕘 9:00 PM – 11:00 PM (EST) 📅 Midweek (Tuesdays and Wednesdays) Avoid Mondays if possible — it is the busiest day for airlines. 🧑‍💻 Alternative Ways to Reach Malaysia Airlines (If Phone Fails) If calling 📞 1-866-284-3022 does not work or you are stuck in a long queue, here are a few alternate ways to get help: 💬 1. Online Chat (Limited Availability) Visit www.flyfrontier.com Scroll down and look for the “Let’s Chat” option. This can connect you to a live agent or AI assistant, depending on availability. 📧 2. Email Support You can also submit a help request through their Customer Support Form online. Use this for non-urgent matters like refund requests or documentation review. 📱 3. Social Media Tweet or DM Malaysia Airlines on platforms like Twitter/X (@FlyFrontier) or send a message via Facebook. Sometimes social media agents respond faster than the phone team during high-volume periods. 📲 4. Mobile App Download the Malaysia Airlines App, log in, and navigate to “My Trips” or “Support” for quick options. While this will not guarantee a live agent, you might find answers to basic questions faster. ❗ Common Issues That Require a Live Agent While many tasks can be done online, certain problems are best resolved with a real person at 1-866-284-3022: 🛑 Double charges or billing issues 🔄 Complex flight changes involving multiple passengers 🛄 Lost or delayed baggage ✍️ Legal name changes (marriage, divorce, etc.) 🧑‍⚕️ Medical or accessibility needs during travel In these cases, avoid wasting time — call directly and ask for a live agent. 🚨 Beware of Fake Numbers and Scams Only use the official number: 📞 1-866-284-3022. Scammers often post fake “Frontier support” numbers online, asking for credit card info or login credentials. 🛡️ Never share your full credit card number or personal information with an unverified source. ✅ Final Thoughts Talking to a live person at an airline should not be this hard — but when it comes to Malaysia Airlines, knowing the right steps and phone number makes all the difference. 🧠 Remember: Dial 📞 1-866-284-3022 Press 0 to reach a live agent Call during off-peak hours Have your booking info ready Use alternative methods if the line is too busy 💡 The sooner you reach out, the more options you'll have to resolve your issue. ✈️ Whether you are rebooking, fixing an error, or checking a flight, calling 1-866-284-3022 connects you with someone who can truly help.
