Automated description summarized from trusted sources.

CVE-2025-13350 identifies a Stored Cross-Site Scripting (XSS) vulnerability found in the SearchIQ – The Search Solution plugin for WordPress. This flaw affects all versions of the plugin up to and including 4.7. The vulnerability stems from inadequate input sanitization and output escaping of user-supplied attributes within the plugin's 'siq_searchbox' shortcode. This oversight enables authenticated attackers, specifically those with contributor-level access or higher, to inject arbitrary web scripts into pages. These injected scripts would then execute whenever a user accesses an affected page.

Description: Ubuntu Linux 6.8 GA retains the legacy AF_UNIX garbage collector but backports upstream commit 8594d9b85c07 ("af_unix: Don’t call skb_get() for OOB skb"). When orphaned MSG_OOB sockets hit unix_gc(), the garbage collector still calls kfree_skb() as if OOB SKBs held two references; on Ubuntu Linux 6.8 (Noble Numbat) kernel tree, they have only the queue reference, so the buffer is freed while still reachable and subsequent queue walks dereference freed memory, yielding a reliable local privilege escalation (LPE) caused by a use-after-free (UAF). Ubuntu builds that have already taken the new GC stack from commit 4090fa373f0e, and mainline Linux kernels shipping that infrastructure are unaffected because they no longer execute the legacy collector path. This issue affects Ubuntu Linux from 6.8.0-56.58 before 6.8.0-84.84.
