- Summary
- CVE-2026-23071 affecting package kernel for versions less than 6.6.126.1-1
- Details
-
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->spinlockflags' was passed directly to 'hwspinlocktimeoutirqsave'. 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.
