CVE-2026-23153 Details
Description
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 completion event concurrently. This commit fixes the bug by put timer start for split transaction expiration into the scope of lock. The value of jiffies in card structure is referred before acquiring the lock.
A race condition vulnerability has been identified in the Linux kernel's Firewire core component, specifically in how transaction lists are managed. The issue arises because the transaction list is processed without acquiring the necessary lock on the Firewire card, leading to potential conflicts when handling acknowledgment responses and request completions simultaneously. This vulnerability affects the stable versions of the Linux kernel.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. The specific commit that resolves this issue is available in the Linux stable tree.
