A use-after-free issue was addressed with improved memory management. This issue is fixed in Safari 26.5, iOS 26.5 and iPadOS 26.5, macOS Tahoe 26.5, tvOS 26.5, visionOS 26.5, watchOS 26.5. Processing maliciously crafted web content may lead to an unexpected process crash.
A flaw was found in WebKitGTK. Processing malicious web content can cause a use-after-free issue due to improper memory management and result in an unexpected process crash.
Отчет
To exploit this issue, an attacker needs to trick a user into processing or loading malicious web content. Due to this reason, this flaw has been rated with an important severity. Additionally, this issue can cause an unexpected process crash but the possibility of remote code execution is not discarded.
Меры по смягчению последствий
Do not process or load untrusted web content with WebKitGTK. In Red Hat Enterprise Linux 7, the following packages require WebKitGTK4: evolution-data-server, glade, gnome-boxes, gnome-initial-setup, gnome-online-accounts, gnome-shell, shotwell, sushi and yelp. This vulnerability can only be exploited when these packages are installed in the system and being used via a graphical interface to process untrusted web content, via GNOME for example. In gnome-shell, the vulnerability can be exploited by an attacker from the local network without user interaction. To mitigate this vulnerability, consider removing these packages. Note that some of these packages are required by GNOME, removing them will also remove GNOME and other packages, breaking functionality. However, the server can still be used via the terminal interface. Additionally, WebKitGTK3 is not required by any package. Therefore, it can be removed without consequences or break of functionality.
