Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
regmap: Fix race condition in hwspinlock irqsave routine<br />
<br />
Previously, the address of the shared member &#39;&map->spinlock_flags&#39; was<br />
passed directly to &#39;hwspin_lock_timeout_irqsave&#39;. This creates a race<br />
condition where multiple contexts contending for the lock could overwrite<br />
the shared flags variable, potentially corrupting the state for the<br />
current lock owner.<br />
<br />
Fix this by using a local stack variable &#39;flags&#39; to store the IRQ state<br />
temporarily.
