CVE-2026-23071

In the Linux kernel, the following vulnerability has been resolved:

regmap: Fix race condition in hwspinlock irqsave routine

Previously, the address of the shared member '&map->spinlock_flags' was

passed directly to 'hwspin_lock_timeout_irqsave'. This creates a race

condition where multiple contexts contending for the lock could overwrite

the shared flags variable, potentially corrupting the state for the

current lock owner.

Fix this by using a local stack variable 'flags' to store the IRQ state

temporarily.
