Improper resource shutdown or release in Linux kernel - CVE-2025-39695

Vulnerability identifier: #VU114965

CSH Severity: Low

CVSS v4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2025-39695

CWE-ID: CWE-404

Exploitation vector: Local access

Exploit availability: No public exploit available

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

The vulnerability exists due to failure to properly release resources within the rxe_qp_init_req() function in drivers/infiniband/sw/rxe/rxe_qp.c, within the rxe_prepare(), rxe_send(), rxe_loopback() and rxe_init_packet() functions in drivers/infiniband/sw/rxe/rxe_net.c. A local user can perform a denial of service (DoS) attack.
