CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-47659 – smack: tcp: ipv4, fix incorrect labeling
https://notcve.org/view.php?id=CVE-2024-47659
In the Linux kernel, the following vulnerability has been resolved: smack: tcp: ipv4, fix incorrect labeling Currently, Smack mirrors the label of incoming tcp/ipv4 connections: when a label 'foo' connects to a label 'bar' with tcp/ipv4, 'foo' always gets 'foo' in returned ipv4 packets. So, 1) returned packets are incorrectly labeled ('foo' instead of 'bar') 2) 'bar' can write to 'foo' without being authorized to write. Here is a scenario how to see this: * Take two machines, let's call them C and S, with active Smack in the default state (no settings, no rules, no labeled hosts, only builtin labels) * At S, add Smack rule 'foo bar w' (labels 'foo' and 'bar' are instantiated at S at this moment) * At S, at label 'bar', launch a program that listens for incoming tcp/ipv4 connections * From C, at label 'foo', connect to the listener at S. (label 'foo' is instantiated at C at this moment) Connection succeedes and works. * Send some data in both directions. * Collect network traffic of this connection. All packets in both directions are labeled with the CIPSO of the label 'foo'. Hence, label 'bar' writes to 'foo' without being authorized, and even without ever being known at C. If anybody cares: exactly the same happens with DCCP. This behavior 1st manifested in release 2.6.29.4 (see Fixes below) and it looks unintentional. At least, no explanation was provided. I changed returned packes label into the 'bar', to bring it into line with the Smack documentation claims. • https://git.kernel.org/stable/c/d3f56c653c65f170b172d3c23120bc64ada645d8 https://git.kernel.org/stable/c/5b4b304f196c070342e32a4752e1fa2e22fc0671 https://git.kernel.org/stable/c/a948ec993541db4ef392b555c37a1186f4d61670 https://git.kernel.org/stable/c/0aea09e82eafa50a373fc8a4b84c1d4734751e2c https://git.kernel.org/stable/c/0776bcf9cb6de46fdd94d10118de1cf9b05f83b9 https://git.kernel.org/stable/c/4be9fd15c3c88775bdf6fa37acabe6de85beebff https://git.kernel.org/stable/c/d3703fa94116fed91f64c7d1c7d284fb4369070f https://git.kernel.org/stable/c/2fe209d0ad2e2729f7e22b9b31a86cc3f •

https://notcve.org/view.php?id=CVE-2024-47658
In the Linux kernel, the following vulnerability has been resolved: crypto: stm32/cryp - call finalize with bh disabled The finalize operation in interrupt mode produce a produces a spinlock recursion warning. The reason is the fact that BH must be disabled during this process. • https://git.kernel.org/stable/c/d93a2f86b0a998aa1f0870c85a2a60a0771ef89a https://git.kernel.org/stable/c/5d734665cd5d93270731e0ff1dd673fec677f447 https://git.kernel.org/stable/c/56ddb9aa3b324c2d9645b5a7343e46010cf3f6ce •

https://notcve.org/view.php?id=CVE-2024-46871
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Correct the defined value for AMDGPU_DMUB_NOTIFICATION_MAX [Why & How] It actually exposes '6' types in enum dmub_notification_type. Not 5. Using smaller number to create array dmub_callback & dmub_thread_offload has potential to access item out of array bound. Fix it. • https://git.kernel.org/stable/c/e1896f381d27466c26cb44b4450eae05cd59dfd0 https://git.kernel.org/stable/c/9f404b0bc2df3880758fb3c3bc7496f596f347d7 https://git.kernel.org/stable/c/800a5ab673c4a61ca220cce177386723d91bdb37 https://git.kernel.org/stable/c/c592b6355b9b57b8e59fc5978ce1e14f64488a98 https://git.kernel.org/stable/c/ad28d7c3d989fc5689581664653879d664da76f0 •
CVSS: -EPSS: 0%CPEs: 2EXPL: 0CVE-2024-46870 – drm/amd/display: Disable DMCUB timeout for DCN35
https://notcve.org/view.php?id=CVE-2024-46870
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Disable DMCUB timeout for DCN35 [Why] DMCUB can intermittently take longer than expected to process commands. Old ASIC policy was to continue while logging a diagnostic error - which works fine for ASIC without IPS, but with IPS this could lead to a race condition where we attempt to access DCN state while it's inaccessible, leading to a system hang when the NIU port is not disabled or register accesses that timeout and the display configuration in an undefined state. [How] We need to investigate why these accesses take longer than expected, but for now we should disable the timeout on DCN35 to avoid this race condition. Since the waits happen only at lower interrupt levels the risk of taking too long at higher IRQ and causing a system watchdog timeout are minimal. • https://git.kernel.org/stable/c/31c254c9cd4b122a10db297124f867107a696d83 https://git.kernel.org/stable/c/7c70e60fbf4bff1123f0e8d5cb1ae71df6164d7f •
