An unprivileged local user can exploit this by sending a specially crafted message to PID1, causing the stack pointer to jump over the stack guard pages into an unmapped memory region and trigger a denial of service (systemd PID1 crash and kernel panic).\n\n * [CVE-2020-12888](<https://vulners.com/cve/CVE-2020-12888>)\n\nThe VFIO PCI driver in the Linux kernel through 5.6.13 mishandles attempts to access disabled memory space.\n\n * [CVE-2020-36385](<https://vulners.com/cve/CVE-2020-36385>)\n\nAn issue was discovered in the Linux kernel before 5.10. drivers/infiniband/core/ucma.c has a use-after-free because the ctx is reached via the ctx_list in some ucma_migrate_id situations where ucma_close is called, aka CID-f5449e74802c.\n\nImpact\n\nThere is no impact; F5 products are not affected by this vulnerability.\n", "published": "2022-09-05T10:48:00", "modified": "2022-09-05T10:48:00", "epss": [{"cve": "CVE-2019-6454", "epss": 0.00044, "percentile": 0.08334, "modified":
