CVE-2016-10088 (GCVE-0-2016-10088)
Vulnerability from cvelistv5 – Published: 2016-12-30 18:00 – Updated: 2024-08-06 03:07
VLAI
EPSS
Summary
The sg implementation in the Linux kernel through 4.9 does not properly restrict write operations in situations where the KERNEL_DS option is set, which allows local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device, related to block/bsg.c and drivers/scsi/sg.c. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9576.
Severity
No CVSS data available.

Summary
The proc_keys_show function in security/keys/proc.c in the Linux kernel through 4.8.2, when the GNU Compiler Collection (gcc) stack protector is enabled, uses an incorrect buffer size for certain timeout data, which allows local users to cause a denial of service (stack memory corruption and panic) by reading the /proc/keys file.
Severity
No CVSS data available.

CVE-2016-9604 (GCVE-0-2016-9604)
Vulnerability from cvelistv5 – Published: 2018-07-11 13:00 – Updated: 2024-08-06 02:59
VLAI
EPSS
Summary
It was discovered in the Linux kernel before 4.11-rc8 that root can gain direct access to an internal keyring, such as '.dns_resolver' in RHEL-7 or '.builtin_trusted_keys' upstream, by joining it as its session keyring. This allows root to bypass module signature verification by adding a new public key of its own devising to the keyring.

Vulnerability from cvelistv5 – Published: 2016-12-28 07:42 – Updated: 2024-08-06 02:59
VLAI
EPSS
Summary
Race condition in the netlink_dump function in net/netlink/af_netlink.c in the Linux kernel before 4.6.3 allows local users to cause a denial of service (double free) or possibly have unspecified other impact via a crafted application that makes sendmsg system calls, leading to a free operation associated with a new dump that started earlier than anticipated.
Severity
No CVSS data available.

CVE-2017-2671 (GCVE-0-2017-2671)
Vulnerability from cvelistv5 – Published: 2017-04-05 06:23 – Updated: 2024-08-05 14:02
VLAI
EPSS
Summary
The ping_unhash function in net/ipv4/ping.c in the Linux kernel through 4.10.8 is too late in obtaining a certain lock and consequently cannot ensure that disconnect function calls are safe, which allows local users to cause a denial of service (panic) by leveraging access to the protocol value of IPPROTO_ICMP in a socket system call.
Severity
No CVSS data available.
