CVE-2010-4158 is a vulnerability of currently unknown severity. The sk_run_filter function in net/core/filter.c in the Linux kernel before 2.6.36.2 does not check whether a certain memory location has been initialized before executing a (1) BPF_S_LD_MEM or (2) BPF_S_LDX_MEM instruction, which allows local users to obtain potentially sensitive information from kernel stack memory via a crafted socket filter.. EPSS estimates a 0.87% chance of exploitation in the next 30 days.
