CVE-2025-43368: A use-after-free issue was addressed with improved memory management.

Noroxi assessment

Priority: Monitor (action score 17/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.80% (FIRST EPSS); higher than 56.5% of all records.
Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
Fixed version: webkit2gtk3 (AlmaLinux:8) 2.50.0-1.el8_10; webkit2gtk3-devel (AlmaLinux:8) 2.50.0-1.el8_10; webkit2gtk3-jsc (AlmaLinux:8) 2.50.0-1.el8_10.

Low priority for now. Upgrade to webkit2gtk3 (AlmaLinux:8) 2.50.0-1.el8_10; webkit2gtk3-devel (AlmaLinux:8) 2.50.0-1.el8_10; webkit2gtk3-jsc (AlmaLinux:8) 2.50.0-1.el8_10 or later.
