Last modified
CVE-2021-38205 is a low-severity vulnerability rated 3.3/10 on the CVSS scale. drivers/net/ethernet/xilinx/xilinx_emaclite.c in the Linux kernel before 5.13.3 makes it easier for attackers to defeat an ASLR protection mechanism because it prints a kernel pointer (i.e., the real IOMEM pointer).. EPSS estimates a 0.33% chance of exploitation in the next 30 days.
