Google va Mozilla seshanba kuni mashhur brauzerlarda 200 dan ortiq zaiflikni bartaraf etadigan yangi Chrome va Firefox yangilanishlarini e'lon qildi.
Chrome 156 yangilanishi 52 ta xavfsizlik nuqsoni uchun tuzatishlar bilan keladi, jumladan to'rtta tanqidiy darajadagi kamchilik: FileSystem'dagi xotira buzilishi, FileAPI va Skia'dagi noto'g'ri kirish tekshiruvi, hamda Layout'dagi foydalanishdan keyin bo'shatish (use-after-free).
CVE-2026-118306, FileSystem xatosi, maxsus tayyorlangan HTML sahifa orqali sandboxdan tashqarida ixtiyoriy kod bajarilishiga imkon berishi mumkin.
Shuningdek, 46 ta yuqori darajadagi xato uchun ham tuzatishlar chiqarildi, ularning aksariyati xotira buzilishi, noto'g'ri kirish tekshiruvi va foydalanishdan keyin bo'shatish muammolari.
Google xabar beruvchi tadqiqotchilarga to'lanadigan xato mukofotlarining hech birini aniqlamagan. Qolgan 39 ta zaiflik uchun hech qanday mukofot berilmaydi, ularning aksariyati ichki yoki sun'iy intellekt yordamida topilgan.
Yangi Chrome versiyasi hozirda Windows va macOS uchun 156.0.8078.73/.74, Linux uchun esa 156.0.8078.73 versiyalari sifatida foydalanuvchilarga tarqatilmoqda.

Mozilla Firefox 159 ni 167 ta xavfsizlik nuqsoni, jumladan 108 ta yuqori darajadagi kamchilik uchun tuzatishlar bilan e'lon qildi.
Tuzatishlarning aksariyati brauzerdagi foydalanishdan keyin bo'shatish muammolarini hal qiladi. Shuningdek, bir nechta sandboxdan qochish, huquqni oshirish, noto'g'ri chegaraviy va bir xil manba siyosatini chetlab o'tish muammolari ham tuzatildi.
Seshanba kuni Mozilla shuningdek Thunderbird 159 va 153.6, hamda Firefox ESR 153.6 va 115.44 ni ham ushbu zaifliklarning ko'pchiligi uchun tuzatishlar bilan chiqardi.
Google va Mozilla ushbu xavfsizlik xatolarining hech biri yovuz maqsadlarda ishlatilganini eslatib o'tmadi, ammo foydalanuvchilarga brauzerlarini iloji boricha tezroq yangilash tavsiya etiladi.

Hech kim xavfsizlik so'rovnomasiga ishonmaydi. Biz baribir unga tayanamiz.
B2B bitimlarining deyarli har birini nazorat qiladigan jarayon — yuboruvchining ishonchsizligi va qabul qiluvchining qabul qilishi. Kompaniyalar o'rtasida ishonch uchun nihoyat yaxshiroq asos paydo bo'lmoqda. (Sravish Sridhar)

Chrome and Firefox Updates Patch Over 200 Vulnerabilities
The Chrome 156 update fixes 52 bugs, while Firefox 159 was rolled out with 167 security patches.

Google and Mozilla on Tuesday rolled out fresh Chrome and Firefox updates that resolve more than 200 vulnerabilities in the popular browsers.
The Chrome 156 update arrives with patches for 52 security defects, including four critical-severity flaws: memory corruption in FileSystem, improper input validation in FileAPI and Skia, and use-after-free in Layout.
CVE-2026-118306, the FileSystem bug, could allow arbitrary code execution outside the sandbox through a crafted HTML page.
Patches were also released for 46 high-severity bugs, most of which are memory corruption, improper input validation, and use-after-free issues.
Google has not determined any of the bug bounty rewards to be paid out to the reporting researchers. No reward will be handed out for the remaining 39 vulnerabilities, most of which were found internally or with the aid of AI.
The new Chrome release is now rolling out to users as versions 156.0.8078.73/.74 for Windows and macOS, and as version 156.0.8078.73 for Linux.

Mozilla announced the release of Firefox 159 with patches for 167 security defects, including 108 high-severity flaws.
Most of the fixes resolve use-after-free issues in the browser. Multiple sandbox escape, privilege escalation, incorrect boundary, and same-origin policy bypass issues were also patched.
On Tuesday, Mozilla also released Thunderbird 159 and 153.6, and Firefox ESR 153.6 and 115.44 with patches for many of these vulnerabilities.
Google and Mozilla make no mention of any of these security bugs being exploited in the wild, but users are advised to update their browsers as soon as possible.
