[PATCH openEuler-1.0-LTS] mmc: core: Fix kernel panic when remove non-standard SDIO card
by Cai Xinchen 12 Dec '25

12 Dec '25

From: Matthew Ma <mahongwei(a)zeku.com> stable inclusion from stable-v4.19.264 commit 1fb79478695d92bab1c120ad3dad05252b02a29d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IDBMTC CVE: CVE-2022-50640 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 9972e6b404884adae9eec7463e30d9b3c9a70b18 upstream. SDIO tuple is only allocated for standard SDIO card, especially it causes memory corruption issues when the non-standard SDIO card has removed, which is because the card device's reference counter does not increase for it at sdio_init_func(), but all SDIO card device reference counter gets decreased at sdio_release_func().

[PATCH OLK-6.6] usb: cdns3: gadget: Use-after-free during failed initialization and exit of cdnsp gadget
by Zhang Kunbo 12 Dec '25

12 Dec '25

From: Chen Yufeng <chenyufeng(a)iie.ac.cn> stable inclusion from stable-v6.6.117 commit ea37884097a0931abb8e11e40eacfb25e9fdb5e9 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IDBAG6 CVE: CVE-2025-40314 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 87c5ff5615dc0a37167e8faf3adeeddc6f1344a3 ] In the __cdnsp_gadget_init() and cdnsp_gadget_exit() functions, the gadget structure (pdev->gadget) was freed before its endpoints. The endpoints are linked via the ep_list in the gadget structure. Freeing the gadget first leaves dangling pointers in the endpoint list. When the endpoints are subsequently freed, this results in a use-after-free. Fix: By separating the usb_del_gadget_udc() operation into distinct "del" and "put" steps, cdnsp_gadget_free_endpoints() can be executed prior to the final release of the gadget structure with usb_put_gadget(). A patch similar to bb9c74a5bd14("usb: dwc3: gadget: Free gadget structure only after freeing endpoints").

[PATCH OLK-6.6] wifi: brcmfmac: fix crash while sending Action Frames in standalone AP Mode
by Fanhua Li 12 Dec '25

12 Dec '25

From: Gokul Sivakumar <gokulkumar.sivakumar(a)infineon.com> stable inclusion from stable-v6.6.117 commit 64e3175d1c8a3bea02032e7c9d1befd5f43786fa category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IDBAJ5 CVE: CVE-2025-40321 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 3776c685ebe5f43e9060af06872661de55e80b9a upstream. Currently, whenever there is a need to transmit an Action frame, the brcmfmac driver always uses the P2P vif to send the "actframe" IOVAR to firmware. The P2P interfaces were available when wpa_supplicant is managing the wlan interface. However, the P2P interfaces are not created/initialized when only hostapd is managing the wlan interface. And if hostapd receives an ANQP Query REQ Action frame even from an un-associated STA, the brcmfmac driver tries to use an uninitialized P2P vif pointer for sending the IOVAR to firmware. This NULL pointer dereferencing triggers a driver crash.

This way, even if P2P vif is not available, the IOVAR is sent to firmware on AP vif and the ANQP Query RESP Action frame is transmitted without crashing the driver. Move init_completion() for "send_af_done" from brcmf_p2p_create_p2pdev() to brcmf_p2p_attach(). Because the former function would not get executed when only hostapd is managing wlan interface, and it is not safe to do reinit_completion() later in brcmf_p2p_tx_action_frame(), without any prior init_completion(). And in the brcmf_p2p_tx_action_frame() function, the condition check for P2P Presence response frame is not needed, since the wpa_supplicant is properly sending the P2P Presense Response frame on the P2P-GO vif instead of the P2P-Device vif.

[PATCH openEuler-1.0-LTS] scsi: hpsa: Fix possible memory leak in hpsa_init_one()
by Zhang Kunbo 12 Dec '25

From: Yuan Can <yuancan(a)huawei.com> stable inclusion from stable-v4.19.270 commit f4d1c14e8b404766ff2bb8644bb19443d73965de category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IDBMU6 CVE: CVE-2022-50646 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 9c9ff300e0de07475796495d86f449340d454a0c ] The hpda_alloc_ctlr_info() allocates h and its field reply_map. However, in hpsa_init_one(), if alloc_percpu() failed, the hpsa_init_one() jumps to clean1 directly, which frees h and leaks the h->reply_map. Fix by calling hpda_free_ctlr_info() to release h->replay_map and h instead free h directly.
