{"id":"CVE-2024-49929","summary":"wifi: iwlwifi: mvm: avoid NULL pointer dereference","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: iwlwifi: mvm: avoid NULL pointer dereference\n\niwl_mvm_tx_skb_sta() and iwl_mvm_tx_mpdu() verify that the mvmvsta\npointer is not NULL.\nIt retrieves this pointer using iwl_mvm_sta_from_mac80211, which is\ndereferencing the ieee80211_sta pointer.\nIf sta is NULL, iwl_mvm_sta_from_mac80211 will dereference a NULL\npointer.\nFix this by checking the sta pointer before retrieving the mvmsta\nfrom it. If sta is not NULL, then mvmsta isn't either.","modified":"2026-04-16T04:30:21.756622262Z","published":"2024-10-21T18:01:52.450Z","related":["SUSE-SU-2024:3983-1","SUSE-SU-2024:3984-1","SUSE-SU-2024:3985-1","SUSE-SU-2024:3986-1","SUSE-SU-2024:4100-1","SUSE-SU-2024:4318-1","SUSE-SU-2024:4364-1","SUSE-SU-2024:4387-1","SUSE-SU-2025:0034-1","SUSE-SU-2025:20163-1","SUSE-SU-2025:20164-1","SUSE-SU-2025:20246-1","SUSE-SU-2025:20247-1","USN-7276-1","USN-7277-1","openSUSE-SU-2024:14500-1","openSUSE-SU-2025:14705-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/49xxx/CVE-2024-49929.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/557a6cd847645e667f3b362560bd7e7c09aac284"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6dcadb2ed3b76623ab96e3e7fbeda1a374d01c28"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c0b4f5d94934c290479180868a32c15ba36a6d9e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cbc6fc9cfcde151ff5eadaefdc6155f99579384f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cdbf51bfa4b0411820806777da36d93d49bc49a1"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/03/msg00001.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/49xxx/CVE-2024-49929.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-49929"},{"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":"5b577a90fb3d86447ee86f8e0c6ddbd5da2ef8c9"},{"fixed":"cbc6fc9cfcde151ff5eadaefdc6155f99579384f"},{"fixed":"6dcadb2ed3b76623ab96e3e7fbeda1a374d01c28"},{"fixed":"cdbf51bfa4b0411820806777da36d93d49bc49a1"},{"fixed":"c0b4f5d94934c290479180868a32c15ba36a6d9e"},{"fixed":"557a6cd847645e667f3b362560bd7e7c09aac284"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-49929.json"}}],"schema_version":"1.7.5"}
