Upgrade urgency SECURITY: This release includes security fixes we recommend you apply as soon as possible.

Security Fixes
  • GHSA-jcj7-v34w-v9vv: Fix a use-after-free in RDMA connection handling that could allow an authenticated client to crash the server using CLIENT KILL. Only affects servers built with USE_RDMA and configured with an RDMA listener (#4534)
Bug Fixes
  • Fix a double-free crash when a module timer callback stops its own timer with ValkeyModule_StopTimer by @quanyeyang (#4211)

USN-8705-2: OpenZFS vulnerability

Ubuntu Security Advisories
10 hours 6 minutes ago
USN-8705-1 fixed vulnerabilities in OpenZFS. This update provides the corresponding fix for OpenZFS on Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. Original advisory details: It was discovered that OpenZFS incorrectly handled authorization checks for certain ioctl operations on Linux. A local attacker could possibly use this issue to perform pool-administrative operations or access privileged information, resulting in an authorization bypass.

USN-8704-1: GNU cpio vulnerabilities

Ubuntu Security Advisories
18 hours 31 minutes ago
It was discovered that cpio incorrectly sanitized hard-link targets when extracting tar archives in copy-in mode. If a user or automated system were tricked into extracting a specially crafted tar archive, an attacker could possibly use this issue to create hard links to files outside the extraction directory, even when using the --no-absolute-filenames option. (CVE-2026-66484) It was discovered that cpio did not properly bound the stack memory allocated for pathnames during archive extraction. If a user or automated system were tricked into extracting a specially crafted cpio archive, an attacker could possibly use this issue to cause cpio to crash, resulting in a denial of service. (CVE-2026-66485) It was discovered that cpio did not properly escape archive member names when listing archive contents. If a user or automated system were tricked into listing a specially crafted archive, an attacker could possibly use this issue to inject misleading output or malicious terminal control sequences. (CVE-2026-66486)
