Linux Kernel thiab Qualcomm Adreno GPU Zero-Day Vulnerabilities: Kev Sib Tw Sib Nqus
Lub Linux ntsiav thiab Qualcomm Adreno GPU tsis ntev los no tau cuam tshuam los ntawm qhov tsis zoo ntawm xoom-hnub, uas yog Dirty Frag thiab peb qhov tsis zoo hauv Adreno GPU tsav tsheb. Cov kev tsis zoo no ua rau muaj kev pheej hmoo tseem ceeb ntawm kev nyab xeeb, vim tias lawv tuaj yeem siv tau kom tau txais kev txiav txim siab hauv paus rau feem ntau Linux faib thiab cuam tshuam cov khoom siv hauv Android.
Dirty Frag: Linux Kernel Zero-Day Vulnerability
Dirty Frag yog Linux kernel vulnerability uas tso cai rau cov neeg siv tsis tau txais txiaj ntsig kom tau txais kev txiav txim siab hauv paus rau feem ntau Linux faib. Qhov tsis zoo yog tshwm sim los ntawm qhov tsis txaus ntseeg hauv cov ntsiav kev tuav ntawm cov pob khoom tawg, uas tuaj yeem siv los ua qhov kev txiav txim siab tsis ncaj ncees nrog cov cai tshwj xeeb. Raws li Hyunwoo Kim qhov kev tshaj tawm piav qhia, qhov tsis zoo cuam tshuam rau Linux ntsiav versions 5.10 thiab tom qab ntawd. Qhov kev pheej hmoo no tshwj xeeb tshaj yog vim nws tuaj yeem siv tau kom tau txais cov hauv paus nkag, uas tuaj yeem ua rau tsis muaj kev tso cai nkag mus rau cov ntaub ntawv rhiab thiab cov tshuab.
💡 Key Takeaway: Dirty Frag yog qhov tseem ceeb ntawm qhov tsis zoo uas yuav tsum tau saib xyuas tam sim los ntawm cov kws tshaj lij thev naus laus zis txhawm rau txhim kho lawv cov kab ke. Qhov tsis muaj zog tuaj yeem raug siv kom tau txais cov hauv paus nkag, uas tuaj yeem ua rau tsis muaj kev tso cai nkag mus rau cov ntaub ntawv rhiab thiab cov tshuab. Txhawm rau txo qhov tsis zoo no, cov neeg siv Linux tuaj yeem siv thaj chaw muab los ntawm Linux ntsiav hauv zej zog, uas kho qhov tsis txaus ntseeg hauv cov ntsiav tshuaj tuav cov pob khoom tawg thiab tiv thaiv kev siv.

Piv txwv ntawm yuav ua li cas siv Dirty Frag thaj siv Git
git fetch https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master git cherry-pick -x <patch_hash>
Tsis tas li ntawd, cov neeg siv tuaj yeem teeb tsa lawv lub tshuab siv lub thawv thiab microVM sandboxes, uas tuaj yeem muab cov txheej txheem ntxiv ntawm kev ruaj ntseg tiv thaiv kernel vulnerabilities. Qhov no yog vim lub thawv thiab microVM sandboxes tuaj yeem cais cov kernel los ntawm tus so ntawm lub kaw lus, tiv thaiv kev siv ntawm qhov tsis zoo.
### Qualcomm Adreno GPU Zero-Day Flaws
Qualcomm tau hais txog peb qhov teeb meem tseem ceeb ntawm lub hnub poob hauv nws cov Adreno GPU tsav tsheb, uas tau siv rau hauv cov phiaj xwm tawm tsam tawm tsam Android. Cov kev tsis zoo cuam tshuam rau Adreno GPU tus neeg tsav tsheb tuav ntawm kev faib lub cim xeeb thiab tuaj yeem siv los ua cov cai tsis raug cai nrog cov cai tshwj xeeb. Raws li [Qualcomm's security bulletin](https://www.qualcomm.com/products/security/bulletins), qhov tsis zoo cuam tshuam rau Adreno GPU tsav tsheb versions 540 thiab tom qab ntawd.
| Vulnerability | Description | Muaj feem cuam tshuam |
| --- | --- | --- |
| CVE-2026-43285 | Nco faib qhov tsis haum | Adreno GPU tsav tsheb 540 thiab tom qab |
| CVE-2026-43286 | Nco faib qhov tsis haum | Adreno GPU tsav tsheb 540 thiab tom qab |
| CVE-2026-43287 | Nco faib qhov tsis haum | Adreno GPU tsav tsheb 540 thiab tom qab |
> ⚠️ ** Kev pheej hmoo ntawm kev tsim vaj tsev: ** Lub Qualcomm Adreno GPU xoom-hnub qhov tsis zoo qhia txog qhov tseem ceeb ntawm kev ua kom cov cuab yeej tsav tsheb mus txog hnub tim thiab ruaj ntseg tiv thaiv kev siv dag zog. Kev ua tsis tiav tuaj yeem ua rau tsis muaj kev tso cai nkag mus rau cov ntaub ntawv thiab cov tshuab. Txhawm rau txo qhov tsis zoo no, cov neeg siv Android tuaj yeem hloov kho lawv cov cuab yeej mus rau qhov tseeb software version, uas suav nrog Adreno GPU tsav tsheb.

Sib piv cov tswv yim txo qis
Cov lus hauv qab no sib piv cov tswv yim txo qis rau Dirty Frag thiab Qualcomm Adreno GPU xoom-hnub qhov tsis zoo:
| Lub tswv yim txo qis | qias neeg | Qualcomm Adreno GPU |
|---|---|---|
| Patching | Thov Linux kernel thaj | Hloov kho Adreno GPU tsav tsheb |
| Thawv thiab microVM sandboxes | Configure thawv thiab microVM sandboxes | Tsis siv tau |
| Ruaj ntseg khau raj | Tsis siv tau | Configure ruaj ntseg khau raj mechanisms |
Kev Txom Nyem thiab Tiv Thaiv
Txhawm rau tiv thaiv kev siv cov kev tsis zoo no, cov neeg siv yuav tsum siv thaj ua rau thaj, teeb tsa kev ruaj ntseg khau raj, thiab siv lub thawv thiab microVM sandboxes. Los ntawm kev ua cov kauj ruam no, cov neeg siv tuaj yeem tiv thaiv kev ua haujlwm ntawm qhov tsis zoo thiab tiv thaiv lawv lub tshuab thiab cov ntaub ntawv. Nws tseem yog ib qho tseem ceeb uas yuav tsum tau ua kom cov cuab yeej tsav tsheb mus txog hnub tim thiab ruaj ntseg tiv thaiv kev siv dag zog.
