CVE-2026-53258
Full vulnerability record from the local CVENow database.
Description
In the Linux kernel, the following vulnerability has been resolved: wifi: fix leak if split 6 GHz scanning fails rdev->int_scan_req is leaked if cfg80211_scan() fails. Note that it's supposed to be released at ___cfg80211_scan_done() but this doesn't happen as rdev->scan_req is NULL at that point, too, leading to the early return from the freeing function. unreferenced object 0xffff8881161d0800 (size 512): comm "wpa_supplicant", pid 379, jiffies 4294749765 hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00 00 00 00 00 00 00 00 f0 81 13 16 81 88 ff ff ................ backtrace (crc c867fdb6): kmemleak_alloc+0x89/0x90 __kmalloc_noprof+0x2fd/0x410 cfg80211_scan+0x133/0x730 nl80211_trigger_scan+0xc69/0x1cc0 genl_family_rcv_msg_doit+0x204/0x2f0 genl_rcv_msg+0x431/0x6b0 netlink_rcv_skb+0x143/0x3f0 genl_rcv+0x27/0x40 netlink_unicast+0x4f6/0x820 netlink_sendmsg+0x797/0xce0 __sock_sendmsg+0xc4/0x160 ____sys_sendmsg+0x5e4/0x890 ___sys_sendmsg+0xf8/0x180 __sys_sendmsg+0x136/0x1e0 __x64_sys_sendmsg+0x76/0xc0 x64_sys_call+0x13f0/0x17d0 Found by Linux Verification Center (linuxtesting.org).
