CVE-2026-98824 wifi: mac80211: validate TX status rate metadata

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: validate TX status rate metadata minstrelhttxstatus converts the HT/VHT rate reported in a TX status into a group and rate index and uses those to index the minstrelht rate tables. The existing validation only...

CVE-2026-98824

The Linux kernel contains a vulnerability in the wifi: mac80211 component where the minstrel_ht_tx_status() function fails to sufficiently validate HT/VHT rate metadata. Specifically, it did not verify if the reported MCS , spatial stream count , and bandwidth were representable by the minstrel_h...

CVE-2026-98823 wifi: cfg80211: preserve hidden-group beacon IE ownership

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: preserve hidden-group beacon IE ownership A hidden-group probe-response entry borrows its beacon IEs from the group's beacon entry. cfg80211updateassocbssentry can pass such an entry to cfg80211updateknownbss when...

CVE-2026-98823

The Linux kernel contains a vulnerability in the cfg80211 component where a hidden-group probe-response entry borrows beacon IEs from the group's beacon entry. During a channel switch, the function cfg80211_update_assoc_bss_entry() can pass such an entry to cfg80211_update_known_bss(). This resul...

CVE-2026-98822 wifi: mac80211: prevent AP VLAN tx from other interfaces

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: prevent AP VLAN tx from other interfaces Since the station lookup was factored out of ieee80211buildhdr, ieee80211lookuprasta uses stainfogetbss for all AP and AP VLAN frames, not only for control port frames. A...

CVE-2026-98822

The Linux kernel contains a vulnerability in the mac80211 WiFi subsystem. Due to the station lookup being factored out of ieee80211_build_hdr(), the ieee80211_lookup_ra_sta() function incorrectly uses sta_info_get_bss() for all AP and AP VLAN frames. This causes a unicast frame sent on one interf...

CVE-2026-98821

The Linux kernel contains a vulnerability where IOPOLL calls bio_poll() on uio_meta instead of a bio structure when user integrity metadata is present. This occurs because IOCB_HAS_METADATA leaves iocb->private as uio_meta, but iocb_bio_iopoll() expects a bio, and since commit 2729a60bbfb9, me...

CVE-2026-98821 block: reject polled dio with user integrity metadata

In the Linux kernel, the following vulnerability has been resolved: block: reject polled dio with user integrity metadata IOCBHASMETADATA leaves iocb-private as a uiometa, while iocbbioiopoll expects a bio. Since 2729a60bbfb9, metadata I/O always uses blkdevdirectIO, which never publishes the bio...

CVE-2026-98820

The Linux kernel contains a vulnerability in blk-mq where cached requests, initially allocated for one operation, could be reused for another. Specifically, if a passthrough command has RQF_USE_SCHED cleared, subsequent read/write bios might use these flags incorrectly. This results in requests b...
