Memory leak in Linux kernel - CVE-2019-19077

Vulnerability identifier: #VU23036

CSH Severity: Low

CVSS v4: 6.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2019-19077

CWE-ID: CWE-401

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to memory leak within the "bnxt_re_create_srq()" function in "drivers/infiniband/hw/bnxt_re/ib_verbs.c" file. A local attacker can cause a denial of service condition (memory consumption) by triggering "ib_copy_to_udata()" failures.
