CVE-2015-3636 (GCVE-0-2015-3636)

Vulnerability from cvelistv5 – Published: 2015-08-06 01:00 – Updated: 2024-08-06 05:47
VLAI
Summary
The ping_unhash function in net/ipv4/ping.c in the Linux kernel before 4.0.3 does not initialize a certain list data structure during an unhash operation, which allows local users to gain privileges or cause a denial of service (use-after-free and system crash) by leveraging the ability to make a SOCK_DGRAM socket system call for the IPPROTO_ICMP or IPPROTO_ICMPV6 protocol, and then making a connect system call after a disconnect.
Severity
No CVSS data available.
