CVE-2026-53258

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> wifi: fix leak if split 6 GHz scanning fails<br /> <br /> rdev-&gt;int_scan_req is leaked if cfg80211_scan() fails. Note that it&amp;#39;s<br /> supposed to be released at ___cfg80211_scan_done() but this doesn&amp;#39;t happen<br /> as rdev-&gt;scan_req is NULL at that point, too, leading to the early return<br /> from the freeing function.<br /> <br /> unreferenced object 0xffff8881161d0800 (size 512):<br /> comm "wpa_supplicant", pid 379, jiffies 4294749765<br /> hex dump (first 32 bytes):<br /> 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................<br /> 00 00 00 00 00 00 00 00 f0 81 13 16 81 88 ff ff ................<br /> backtrace (crc c867fdb6):<br /> kmemleak_alloc+0x89/0x90<br /> __kmalloc_noprof+0x2fd/0x410<br /> cfg80211_scan+0x133/0x730<br /> nl80211_trigger_scan+0xc69/0x1cc0<br /> genl_family_rcv_msg_doit+0x204/0x2f0<br /> genl_rcv_msg+0x431/0x6b0<br /> netlink_rcv_skb+0x143/0x3f0<br /> genl_rcv+0x27/0x40<br /> netlink_unicast+0x4f6/0x820<br /> netlink_sendmsg+0x797/0xce0<br /> __sock_sendmsg+0xc4/0x160<br /> ____sys_sendmsg+0x5e4/0x890<br /> ___sys_sendmsg+0xf8/0x180<br /> __sys_sendmsg+0x136/0x1e0<br /> __x64_sys_sendmsg+0x76/0xc0<br /> x64_sys_call+0x13f0/0x17d0<br /> <br /> Found by Linux Verification Center (linuxtesting.org).
