CVE ID : CVE-2025-40174<\/p>\n

Description : In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
x86\/mm: Fix SMP ordering in switch_mm_irqs_off()<\/p>\n
Stephen noted that it is possible to not have an smp_mb() between
\nthe loaded_mm store and the tlb_gen load in switch_mm(), meaning the
\nordering against flush_tlb_mm_range() goes out the window, and it
\nbecomes possible for switch_mm() to not observe a recent tlb_gen
\nupdate and fail to flush the TLBs.<\/p>\n[ dhansen: merge conflict fixed by Ingo ]\n
Severity: 0.0 | NA<\/p>\n
