In the Linux kernel, the following vulnerabilities have been resolved: ASoC: mediatek: common: Fixed a reference count leak in parsedailinkinfo. Added calls to ofnodeput before the returns from ofnodeget and ofnodeput, which can prevent imbalance if the “foreachavailablechildofnode” loop terminat...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: Media: MediTech; vcodec: Fix resource leaks in vdecmsgqueueinit. If any error occurs in vdecmsgqueueinit, we need to set “msgqueue-wdmaaddr.size = 0;”. Normally, this is done within the vdecmsgqueuedeinit function. However, if...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: soc: mediatek: mtk-svs: Enable the IRQ later. If the system does not start from a reset state such as when it is booted via kexec, the peripheral device may trigger an IRQ before the data structures are initialized. 0.227710 Unab...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: PCI: mediatek-gen3 – A refcount leak was addressed in mtkpcieinitirqdomains. The function ofgetchildbyname returns a node pointer whose refcount is incremented. Therefore, we should use ofnodeput on it when we no longer need it. ...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: media: mediatek: vcodec: The use of a spinlock for the context list protection lock was corrected. Previously, a mutex was added to protect the encoder and decoder context lists from unexpected changes originating from the SCP IP...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: - Media: MediTech: vcodec: Added a lock to protect the ctxlist variable, to prevent access to a NULL pointer within the vpudecipihandler function when the ctxlist has been deleted due to an unexpected behavior on the SCP IP...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ASoC: mediatek: mt8195: Fixed error handling in mt8195mt6359rt1019rt5682devprobe. The devicenode pointer is returned by ofparsephandle, with the refcount incremented. We should use ofnodeput on it after the function is completed...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Media: MediTech; vcodec: Cannot set dstbuffer to done when a late decoding error occurs. The core thread will call v4l2m2mbufdone to set the dstbuffer as done for the late architecture. If v4l2m2mbufdoneandjobfinish is called lat...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: clk: mediatek: mt8183 – Added back the SSPM-related clocks. This change reverts to the commit number 860690a93ef23b567f781c1b631623e27190f101. On the MT8183, the SSPM-related clocks were removed due to a claim that they were not...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: iommu/mediatek: Remove clkdisable from mtkiommuremove. After the commit b34ea31fe013 “iommu/mediatek: Always enable the clk on resume”, the iommu clock is controlled by the runtime callback. Therefore, the clkdisable function is...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/mediatek: dsi: Store driver data before invoking mipidsihostregister The call to mipidsihostregister triggers a callback to mtkdsibind, which uses devgetdrvdata to retrieve the mtkdsi struct. Therefore, this structure must be...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/mediatek: Initialization of ddpcomp using devmkcalloc In the case where connroutes is true, an additional slot is allocated in the ddpcomp array. However, the mtkdrmcrtccreate function never seems to initialize this slot duri...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: thermal/drivers/mediatek/lvtsthermal: Fixed a memory leak in the error handling path. If devmkrealloc fails, then ‘efuse’ is leaking memory. Therefore, it should be freed to avoid the memory leak...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/mediatek: A potential NULL dereferencing in mtkcrtcdestroy has been fixed. In mtkcrtccreate, if the call to mboxrequestchannel fails, we set the pointer mtkcrtc-cmdqclient.chan to NULL. In that case, we do not call...
