In the Linux kernel, the following vulnerability has been resolved:

wifi: mac80211: abort chanswitch when leaving a mesh

The code in ieee80211_stop_mesh() leaves CSA active, but leaving the mesh released the channel context, so the CSA finalize work crashes:

Oops: general protection fault, probably for non-canonical address 0xdffffc0000000003 KASAN: null-ptr-deref in range [0x0000000000000018-0x000000000000001f] RIP: 0010:ieee80211_put_srates_elem+0x42/0x640 net/mac80211/util.c:3272 Call Trace: ieee80211_mesh_build_beacon+0xa83/0x1b50 net/mac80211/mesh.c:1093 ieee80211_mesh_rebuild_beacon+0xc7/0x170 net/mac80211/mesh.c:1147 ieee80211_mesh_finish_csa+0x131/0x210 net/mac80211/mesh.c:1542 ieee80211_set_after_csa_beacon net/mac80211/cfg.c:4085 [inline] __ieee80211_csa_finalize net/mac80211/cfg.c:4133 [inline] ieee80211_csa_finalize+0x633/0x1150 net/mac80211/cfg.c:4155 cfg80211_wiphy_work+0x2ab/0x450 net/wireless/core.c:438

Abort the channel switch properly.

BOD 26-04 (CISA's remediation timeline, Table 1)14 days if the affected system is publicly exposed; Fix on system upgrade if it is not.

In CISA KEV no (CISA's KEV catalog) · Automatable no (CISA's BOD 26-04 default) · Technical impact total (CISA's BOD 26-04 default). Where an input reads “CISA's BOD 26-04 default”, no one has published it for this CVE, and CISA's implementation guidance says: “If “Automatable” and “Technical Impact” information items about a CVE ID are not available and the CVE ID is not in the KEV Catalog, CISA will treat its values as “no” and “total,” respectively, until CISA or a third party provides metadata about the CVE ID. CISA will always provide the Vulnrichment data for a CVE ID listed in the KEV Catalog.” Whether your system is publicly exposed is yours to answer. BOD 26-04 binds US Federal Civilian Executive Branch agencies; for anyone else it is CISA's published timeline, a reference rather than an obligation. The directive · how EchelonGraph applies it

(refreshed 16× in last 7d / 21× in last 30d)

Each row is a time one of our pipelines fetched, updated or re-scored this CVE. For example, "NVD update" means NVD published or revised its analysis for this CVE; "MITRE cvelistV5" means we ingested or refreshed it from the CNA feed. An arrow marks a change the record states ("CVSS v3 → 9.1"); EPSS and GHSA rows show the values recorded at that time, not what changed (EPSS values are rounded; hover one for the exact figures).
