In the Linux kernel, the following vulnerability has been resolved: irqchip/gic-v5: Clear per-CPU IRS data on teardown IRS affinity setup publishes an IRS pointer and IAFFID state in the per-CPU data before the remaining IRS initialization can fail. The error path then frees the IRS data without clearing that published state, leaving CPUs associated with freed memory. On initialization failure and normal IRS teardown, clear the per-CPU IRS association by removing the stale pointer to irs_data. Also invalidate the per-CPU IAFFID state for any CPUs that were tied to the IRS before it was freed.
