Google Chrome 147: Security Fixes
Google’s update for Chrome 147 targets several high-risk vulnerabilities, with four critical use-after-free bugs standing out among the fixes.
According to the report, the security vulnerabilities were tracked as CVE-2026-7363, CVE-2026-7361, CVE-2026-7344, and CVE-2026-7343, and they affect the Canvas, iOS, Accessibility, and Views components.
The stable release is now rolling out as version 147.0.7727.137/138 for Windows and macOS, and 147.0.7727.137 for Linux.
This update is a really important one, as memory corruption bugs can sometimes lead to broader attacks, especially if a user visits a malicious website or opens a crafted file.
Mozilla Firefox 150: Security Fixes
On the other hand, the Mozilla Firefox 150.0.1 update focuses on memory safety and fixing security defects that are linked to critical and high-severity issues.
The vulnerabilities are tracked as CVE-2026-7322, CVE-2026-7323, and CVE-2026-7324, and Mozilla says the fixes extend to Firefox ESR 140.10.1 and Firefox ESR 115.35.1 as well.
The ESR release also includes a medium-severity sandbox escape fix, which is important for reducing the impact of a potential exploit.
For enterprise users, the ESR updates are especially important because they provide security coverage without forcing a major version jump.
Why The Update Matters
As we all know, browser updates are often easy to postpone, and people always try to avoid them, but this is the thing that makes them a common target for attackers.
So, for ensuring your safety, when a release addresses critical bugs in core rendering or accessibility components, the safest approach is to update as soon as possible. This will make you less likey falling for online scams.
In practical terms, that means restarting the browser, checking for updates manually, and making sure automatic updates are enabled.
User Action
For Chrome, users can open the browser’s menu and trigger an update check, while Firefox users should apply the latest 150.0.1 build or the corresponding ESR release.
The good news is that both vendors appear to have moved quickly, which reduces the window of exposure for users who update promptly.
