CVE-2026-63989

In the Linux kernel, the following vulnerability has been resolved: bridge: Fix sleep in atomic context in netlink path Since the introduction of the netlink configuration path for bridge ports in commit 25c71c75ac87 "bridge: bridge port parameters over netlink", brsetport was always called with...

CVE-2026-63988

In the Linux kernel, the following vulnerability has been resolved: bridge: Fix sleep in atomic context in sysfs path Since the start of the git history, brportstore always acquired the bridge lock. Back then this decision made sense: The bridge lock protects the STP state of the bridge and its...

CVE-2026-63989

CVE-2026-63989 concerns the Linux kernel bridge netlink path. The issue arises because br_setport() was historically called with the bridge lock held, but br_setport processes many attributes (flags, FDB flushing, multicast, group forward mask, backup port/NHID) that do not require the bridge loc...

CVE-2026-63988

CVE-2026-63988 concerns a Linux kernel fix for sleeping in atomic context during sysfs path handling in bridge brport_store(). The root cause: brport_store() previously held the bridge lock for many attributes; now most attributes don’t require the lock. As a result, calling dev_set_promiscuity()...

CVE-2026-46302

CVE-2026-46302 concerns the Linux kernel SELinux policy handling. The vulnerability arises because multiple processes could concurrently open /sys/fs/selinux/policy, whereas previously only one open was allowed. The root cause is a retained policy_opened flag and a too-large critical section arou...

CVE-2026-23248

CVE-2026-23248 affects the Linux kernel perf/core component, specifically the perf_mmap path that initializes a ring_buffer. The issue is a race between a failing mmap() setup and a concurrent mmap() on a dependent event (e.g., due to output redirection). The ring_buffer pointer (event->rb) is...

Linux Distros Unpatched Vulnerability : CVE-2026-23153

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - In the Linux kernel, the following vulnerability has been resolved: firewire: core: fix race condition against transaction list The list of transaction is...

CVE-2026-23153

In the Linux kernel, the following vulnerability has been resolved: firewire: core: fix race condition against transaction list The list of transaction is enumerated without acquiring card lock when processing AR response event. This causes a race condition bug when processing AT request completi...

CVE-2026-23153

CVE-2026-23153 concerns the Linux kernel regarding a race condition in the FireWire core when enumerating the transaction list without a lock during AR response processing, potentially impacting AT request completion handling. The issue is resolved by moving the timer start for split-transaction ...
