CVE-2025-37964

In the Linux kernel, the following vulnerability has been resolved: x86/mm: Eliminate window where TLB flushes may be inadvertently skipped tl;dr: There is a window in the mm switching code where the new CR3 is set and the CPU should be getting TLB flushes for the new mm. But shouldflushtlb has a...

CVE-2025-37964

CVE-2025-37964 relates to the Linux kernel x86/mm TLB handling. The issue is a bug in should_flush_tlb() that can suppress TLB flushes in a narrow window between load_new_mm_cr3() and writing the new mm state into loaded_mm, risking missed TLB flushes during address space switch. The fix widens t...

CVE-2025-37949

CVE-2025-37949 concerns the Linux kernel XenBus code. The connected docs describe a NULL pointer dereference in xenbus_thread caused by a wake-up path where req may be freed before resuming, and the fix adds two separate kref lifetimes (one for the caller and one for xenbus_thread) with kref_put(...

CVE-2025-37935 net: ethernet: mtk_eth_soc: fix SER panic with 4GB+ RAM

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: mtkethsoc: fix SER panic with 4GB+ RAM If the mtkpollrx function detects the MTKRESETTING flag, it will jump to releasedesc and refill the high word of the SDP on the 4GB RFB. Subsequently, mtkrxclean will process ...
