kernel: ip6: vti: Use ip6_tnl.net in vti6_changelink()

A flaw was found in the Linux kernel's IPv6 Virtual Tunnel Interface vti6 component. An unprivileged local user, particularly within a user namespace, could exploit a vulnerability related to incorrect network namespace handling during the movement of a vti6 tunnel. This issue can lead to a kerne...

kernel: xfrm: input: hold netns during deferred transport reinjection

A flaw was found in the Linux kernel's xfrm input component. The transport-mode reinjection process, which handles network packet re-injection, stores a network namespace pointer that must remain valid until a deferred callback completes. However, a missing reference count for the network namespa...

The Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CIQ crlsa-202667469 advisory. kernel: EDAC/bluefield: Fix potential integer overflow CVE-2024-53161 kernel: wifi: mac80211: Discard Beacon frames to non-broadcast address CVE-2025-7112...

CVE-2026-47549

A flaw was found in nvidia-driver. This vulnerability allows an unprivileged local user to cause a Denial of Service DoS by triggering an invalid memory access NULL pointer dereference in the kernel module. A successful exploit results in a system crash...

CVE-2026-97998

A flaw was found in the Linux kernel's netfilter subsystem. A race condition in the nfnetlinklog packet logging component allows a local user to trigger concurrent instance destruction by issuing an unbind request while a queue destruction event is pending. This issue leads to an invalid memory...

CVE-2026-97971

A flaw was found in the Linux kernel's namespace listing subsystem. When an unauthorized caller attempts to list namespaces, the kernel acquires a reference to a candidate namespace before verifying listing permissions. If access is denied, releasing this reference can cause the kernel to sleep...

CVE-2026-97968

A flaw was found in the Linux kernel's Corsair Commander Pro corsair-cpro hardware monitoring driver. When device registration fails during initialization, debugfs entries are left registered after the associated device data structure has been freed. A local user with access to the debugfs...

PT-2026-103020

Name of the Vulnerable Software and Affected Versions PCRE2 versions prior to 10.49 Description An out-of-bounds write occurs when an attacker-controlled regular expression is used in conjunction with specific JIT API usage. This issue affects the pcre2 jit compile and pcre2 jit match functions,...

CVE-2026-97950

A flaw was found in the Linux kernel's configfs filesystem. A local user could exploit a race condition between creating a symbolic link and deleting its target directory to cause a Denial of Service DoS. When this race condition occurs, the kernel attempts to access a freed directory entry, whic...

CVE-2026-97905

A flaw was found in the Linux kernel's CPU frequency scaling cpufreq subsystem. When creating a frequency policy, the kernel exposes system control files sysfs attributes before the CPU mask memory is zero-initialized. A local user could exploit this race condition by accessing these sysfs...

CVE-2026-97901

A flaw was found in the Linux kernel's Generic Netlink genetlink component. This flaw allows a local user to cause a Denial of Service DoS through a system crash. The vulnerability occurs because the kernel fails to maintain a reference to the target module during a policy dump that spans multipl...

CVE-2026-97621

A flaw was found in the Linux kernel's Rockchip Analogix DP driver. The driver formats a device tree path into a fixed-size stack buffer without verifying the input length. A local user capable of providing an excessively long device tree path can trigger a stack-based buffer overflow, leading to...

CVE-2026-98059

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. This issue allows a local attacker to cause a Denial of Service DoS through a system crash. The vulnerability occurs because the BPF verifier fails to recognize that process-wait tracepoint arguments can be null,...
