Memory leak in Linux kernel - CVE-2025-37743

Vulnerability identifier: #VU108215

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-2025-37743

CWE-ID: CWE-401

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 memory leak within the ath12k_dp_mon_rx_parse_status_tlv() and ath12k_dp_mon_parse_rx_dest() functions in drivers/net/wireless/ath/ath12k/dp_mon.c. A local user can perform a denial of service (DoS) attack.
