The AlmaLinux Security team has released two security updates: one for kernel (moderate severity) and one for libsoup3 (important severity). The kernel update fixes four vulnerabilities, including ones that affect HID, eventpoll, ALSA, and crypto components. The libsoup3 update addresses a single vulnerability related to an out-of-bounds read in cookie date handling in the HTTP library. Both updates are available on AlmaLinux versions 9 and 10, respectively, with detailed information found at the provided links.

ALSA-2025:18183: libsoup3 security update (Important)

Hi,

You are receiving an AlmaLinux Security update email because you subscribed to receive errata notifications from AlmaLinux.

AlmaLinux: 10
Type: Security
Severity: Important
Release date: 2025-10-16

Summary:

Libsoup is an HTTP library implementation in C. It was originally part of a SOAP (Simple Object Access Protocol) implementation called Soup, but the SOAP and non-SOAP parts have now been split into separate packages. libsoup uses the Glib main loop and is designed to work well with GTK applications. This enables GNOME applications to access HTTP servers on the network in a completely asynchronous fashion, very similar to the Gtk+ programming model (a synchronous operation mode is also supported for those who want it), but the SOAP parts were removed long ago.

Security Fix(es):

* libsoup: Out-of-Bounds Read in Cookie Date Handling of libsoup HTTP Library (CVE-2025-11021)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
