Red Hat has issued an important security update for these issues affecting Red Hat Enterprise Linux 9.8 Extended Update Support and related variants.
.NET 11.0 for Red Hat Enterprise Linux has a low severity elevation of privilege vulnerability identified as CVE-2026-62909. This update includes security fixes, bug fixes, and enhancements for the .NET platform, which supports cross-platform application development. The advisory covers updates to SDK and runtime versions 11.0.100~rc.2.26504.105 and 11.0.0~rc.2.26504.105 respectively. The vulnerability allows elevation of privilege but is rated low impact by Red Hat. Updated packages are available for multiple Red Hat Enterprise Linux 9 architectures.
A heap-based buffer overflow vulnerability exists in the raptor2 RDF Parser Toolkit used in Red Hat Enterprise Linux 9.8 Extended Update Support. This flaw occurs in the handling of language tags and could allow arbitrary code execution. Red Hat has issued a security update to address this issue.
A security update for python-oauthlib addresses a privilege escalation vulnerability caused by client identity confusion in token grant handlers (CVE-2026-118669). This issue affects Red Hat Enterprise Linux 9.8 Extended Update Support and related variants. The vulnerability allows an attacker to escalate privileges by exploiting the confusion in client identity during OAuth token grants. Red Hat has released updated packages to fix this issue.
.NET 11.0 for Red Hat Enterprise Linux contains an elevation of privilege vulnerability in ASP.NET Core identified as CVE-2026-114148. This security issue has been addressed in an update to .NET 11.0 RC 3. The update also includes bug fixes and enhancements.

Red Hat has released a security advisory with an important severity rating and recommends applying the update to remediate the issue.
Data::Dump::Streamer versions before 3.00 for Perl allow code injection via unescaped Regexp patterns in _dump_qr.
A Regexp's pattern is written into a qr literal without escaping "$" or "@", so "@{[ ... ]}" and "${\ ... }" in the pattern run as code when the dump is evaluated. An already escaped delimiter gets a second backslash, which leaves the delimiter bare and ends the qr literal early.
An attacker who supplies a pattern that an application compiles, dumps and later restores with eval or do can run arbitrary Perl code.
A use-after-free vulnerability exists in the Accessibility component of Google Chrome versions prior to 157.0.8103.78. This flaw allows a remote attacker to execute arbitrary code within the browser's sandbox by crafting a malicious HTML page. The vulnerability is classified with high severity by Chromium security.
Zipline versions from 4.3.2 up to but not including 4.8.0 have a rate limit bypass vulnerability. This flaw allows unauthenticated attackers to evade throttling mechanisms by spoofing the X-Forwarded-For header when the core.trustProxy setting is enabled. By sending different X-Forwarded-For values per request, attackers can bypass rate limits and perform unlimited guessing attacks against login passwords, TOTP codes, and file or URL passwords.
An information leak vulnerability exists in the Skia component of Google Chrome versions prior to 157.0.8103.78. This flaw allows a remote attacker to obtain cross-origin data by crafting a malicious HTML page. The Chromium project has assigned this issue a high security severity rating.
Zipline versions 4.0.0 up to but not including 4.8.0 contain an upload filter bypass vulnerability. This flaw allows users with upload permissions to bypass administrator restrictions on blocked file types due to a mismatch in how file extensions are checked. The vulnerability arises because the upload handlers compare dotted, case-sensitive extensions against undotted disabledExtensions entries, enabling bypass of file type restrictions.
A use-after-free vulnerability exists in the BrowserTag component of Google Chrome versions prior to 157.0.8103.78. This flaw allows a remote attacker to execute arbitrary code within the sandbox by tricking a user into visiting a crafted HTML page. The vulnerability is classified with high severity by Chromium security.
Zipline versions from 4.6.2 up to but not including 4.8.0 contain a policy bypass vulnerability. Authenticated users can evade administrator-disabled MIME types by modifying file metadata via a PATCH request, allowing them to upload files with disallowed content types such as text/html. This could lead to unauthorized content being served with a disabled MIME type.
A high-severity out-of-bounds read vulnerability exists in the Skia component of Google Chrome versions prior to 157.0.8103.78. This flaw allows a remote attacker who has already compromised the renderer process to leak cross-origin data by using a specially crafted HTML page.
