{"id":"CVE-2023-54016","summary":"wifi: ath12k: Fix memory leak in rx_desc and tx_desc","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: ath12k: Fix memory leak in rx_desc and tx_desc\n\nCurrently when ath12k_dp_cc_desc_init() is called we allocate\nmemory to rx_descs and tx_descs. In ath12k_dp_cc_cleanup(), during\ndescriptor cleanup rx_descs and tx_descs memory is not freed.\n\nThis is cause of memory leak. These allocated memory should be\nfreed in ath12k_dp_cc_cleanup.\n\nIn ath12k_dp_cc_desc_init(), we can save base address of rx_descs\nand tx_descs. In ath12k_dp_cc_cleanup(), we can free rx_descs and\ntx_descs memory using their base address.\n\nTested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1","modified":"2026-04-02T09:45:29.916535Z","published":"2025-12-24T10:55:47.691Z","related":["SUSE-SU-2026:0278-1","SUSE-SU-2026:0281-1","SUSE-SU-2026:0293-1","SUSE-SU-2026:0315-1","SUSE-SU-2026:20477-1","SUSE-SU-2026:20498-1","SUSE-SU-2026:20845-1","SUSE-SU-2026:20876-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/54xxx/CVE-2023-54016.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/afb522b36e76acaa9f8fc06d0a9742d841c47c16"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e16be2d34883eecfe7fd888fcdb76c7a5db5d187"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/54xxx/CVE-2023-54016.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-54016"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"d889913205cf7ebda905b1e62c5867ed4e39f6c2"},{"fixed":"e16be2d34883eecfe7fd888fcdb76c7a5db5d187"},{"fixed":"afb522b36e76acaa9f8fc06d0a9742d841c47c16"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-54016.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.3.0"},{"fixed":"6.5.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-54016.json"}}],"schema_version":"1.7.5"}
