CVE-2025-39739 (published 2025-09-11 17:15:35.873000+00:00)
In the Linux kernel, the following vulnerability has been resolved:

iommu/arm-smmu-qcom: Add SM6115 MDSS compatible

Add the SM6115 MDSS compatible to clients compatible list, as it also
needs that workaround.
Without this workaround, for example, QRB4210 RB2 which is based on
SM4250/SM6115 generates a lot of smmu unhandled context faults during
boot:

arm_smmu_context_fault: 116854 callbacks suppressed
arm-smmu c600000.iommu: Unhandled context fault: fsr=0x402,
iova=0x5c0ec600, fsynr=0x320021, cbfrsynra=0x420, cb=5
arm-smmu c600000.iommu: FSR    = 00000402 [Format=2 TF], SID=0x420
arm-smmu c600000.iommu: FSYNR0 = 00320021 [S1CBNDX=50 PNU PLVL=1]
arm-smmu c600000.iommu: Unhandled context fault: fsr=0x402,
iova=0x5c0d7800, fsynr=0x320021, cbfrsynra=0x420, cb=5
arm-smmu c600000.iommu: FSR    = 00000402 [Format=2 TF], SID=0x420

and also failed initialisation of lontium lt9611uxc, gpu and dpu is
observed:
(binding MDSS components triggered by lt9611uxc have failed)
