(CVE-2025-10263)

Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.

(CVE-2025-10263)

It was discovered that some AMD Zen 2 processors did not properly isolate
shared resources in the operation cache. A local attacker could possibly
use this issue to corrupt instructions executed at a higher privilege
level, resulting in privilege escalation. (CVE-2025-54518)

Unfortunately that update
contained an incomplete fix for CVE-2026-8927. This update fixes the
problem.

Original advisory details:

 Andrew Nesbitt discovered that curl could reuse an existing live
 connection during STARTTLS-based connection upgrades even when the TLS
 configuration did not match. A remote attacker could possibly use this
 issue to cause curl to use an unintended TLS configuration.
 (CVE-2026-8286)

 Muhamad Arga Reksapati discovered that curl incorrectly reused connections
 for Negotiate-authenticated requests when different services were
 involved. A remote attacker could possibly use this issue to access
 resources authenticated for another service. This issue only affected
 Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, Ubuntu 24.04 LTS,
 Ubuntu 25.10, and Ubuntu 26.04 LTS. (CVE-2026-8458)

 It was discovered that curl incorrectly handled cookie parsing in certain
 circumstances. A remote attacker could possibly use this issue to set
 cookies that would be transmitted to unrelated third-party domains. This
 issue only affected Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS,
 Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, Ubuntu 25.10, and Ubuntu 26.04 LTS.
 (CVE-2026-8924)

 Joshua Rogers discovered that curl could double-free a GSASL context when
 handling SASL authentication. A remote attacker could possibly use this
 issue to cause a denial of service, or execute arbitrary code. This issue
 only affected Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, Ubuntu 25.10, and Ubuntu
 26.04 LTS. (CVE-2026-8925)

 Joshua Rogers discovered that curl could select the wrong password from a
 .netrc file when a username was specified in the URL without a password. A
 remote attacker could possibly use this issue to obtain sensitive
 information. This issue only affected Ubuntu 25.10 and Ubuntu 26.04 LTS.
 (CVE-2026-8926)

 Ady Elouej discovered that curl did not clear proxy authentication state
 between requests when reusing a handle with environment-variable proxy
 configuration. A remote attacker could possibly use this issue to obtain
 sensitive credentials. (CVE-2026-8927)

 Guannan Wang, Zhanpeng Liu, Jiashuo Liang, and Guancheng Li discovered
 that curl did not properly clear proxy authentication credentials when
 instructed to do so. A remote attacker could possibly use this issue to
 obtain sensitive credentials. This issue only affected Ubuntu 25.10 and
 Ubuntu 26.04 LTS. (CVE-2026-9079)

 Joshua Rogers discovered that curl contained a use-after-free when
 curl_easy_pause() was called within the event-based socket callback. A
 remote attacker could possibly use this issue to cause a denial of service
 or possibly execute arbitrary code. This issue only affected Ubuntu 25.10
 and Ubuntu 26.04 LTS. (CVE-2026-9080)

 Eunsoo Kim discovered that curl could send early data on a resumed TLS
 session before enforcing certificate verification failure. A  machine-in-
 the-middle attacker could possibly use this issue to obtain  sensitive
 information. This issue only affected Ubuntu 25.10 and Ubuntu  26.04 LTS.
 (CVE-2026-9545)

 Joshua Rogers discovered that curl did not properly reject host key type
 mismatches when using the SSH key callback for SCP and SFTP transfers. A
 machine-in-the-middle attacker could possibly use this issue to
 impersonate a trusted server. This issue only affected Ubuntu 22.04 LTS,
 Ubuntu 24.04 LTS, Ubuntu 25.10, and Ubuntu 26.04 LTS.

file, an attacker could possibly use this issue to execute arbitrary code.
(CVE-2026-46529)

It was discovered that Atril incorrectly handled certain PDF files. An
attacker could possibly use this issue to cause a denial of service or
to execute arbitrary code. This issue only affected Ubuntu 16.04 LTS.
(CVE-2019-1010006)

Andy Nguyen discovered that Atril incorrectly handled certain images. An
attacker could possibly use this issue to expose sensitive information.
This issue only affected Ubuntu 16.04 LTS.

allocation tables in malformed document files. An attacker could possibly
use this issue to cause catdoc to crash or execute arbitrary code.
(CVE-2024-52035)

It was discovered that catdoc incorrectly validated sector sizes when
processing malformed document files, leading to an integer underflow. An
attacker could possibly use this issue to cause catdoc to crash or execute
arbitrary code.
