[PATCH OLK-5.10] pinmux: Use sequential access to access desc->pinmux data

From: Mukesh Ojha <quic_mojha(a)quicinc.com> stable inclusion from stable-v6.6.66 commit 2da32aed4a97ca1d70fb8b77926f72f30ce5fb4b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBIFR8 CVE: CVE-2024-47141 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 5a3e85c3c397c781393ea5fb2f45b1f60f8a4e6e ] When two client of the same gpio call pinctrl_select_state() for the same functionality, we are seeing NULL pointer issue while accessing desc->mux_owner. Let's say two processes A, B executing in pin_request() for the same pin and process A updates the desc->mux_usecount but not yet updated the desc->mux_owner while process B see the desc->mux_usecount which got updated by A path and further executes strcmp and while accessing desc->mux_owner it crashes with NULL pointer. Serialize the access to mux related setting with a mutex lock. cpu0 (process A) cpu1(process B) pinctrl_select_state() { pinctrl_select_state() { pin_request() { pin_request() { ... .... } else { desc->mux_usecount++;

[PATCH OLK-6.6] wifi: mac80211: fix mbss changed flags corruption on 32 bit systems
by Wang Wensheng 07 Feb '25

07 Feb '25

From: Issam Hamdi <ih(a)simonwunderlich.de> stable inclusion from stable-v6.6.70 commit 86772872f9f5097cd03d0e1c6813238bd38c250b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBID2X CVE: CVE-2024-57899 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 49dba1ded8dd5a6a12748631403240b2ab245c34 ] On 32-bit systems, the size of an unsigned long is 4 bytes, while a u64 is 8 bytes. Therefore, when using or_each_set_bit(bit, &bits, sizeof(changed) * BITS_PER_BYTE), the code is incorrectly searching for a bit in a 32-bit variable that is expected to be 64 bits in size, leading to incorrect bit finding. Solution: Ensure that the size of the bits variable is correctly adjusted for each architecture.

Fix this use-after-free issue by dropping of_node_put() in adv7533_parse_dt() and calling of_node_put() in error path of probe() and also in the remove().

[PATCH OLK-6.6] gve: guard XDP xmit NDO on existence of xdp queues
by Wang Liang 07 Feb '25

07 Feb '25

From: Joshua Washington <joshwash(a)google.com> stable inclusion from stable-v6.6.70 commit cbe9eb2c39d09f3c8574febcfa39d8c09d0c7cb5 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBJ6O9 CVE: CVE-2024-57932 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit ff7c2dea9dd1a436fc79d6273adffdcc4a7ffea3 upstream. In GVE, dedicated XDP queues only exist when an XDP program is installed and the interface is up. As such, the NDO XDP XMIT callback should return early if either of these conditions are false. In the case of no loaded XDP program, priv->num_xdp_queues=0 which can cause a divide-by-zero error, and in the case of interface down, num_xdp_queues remains untouched to persist XDP queue count for the next interface up, but the TX pointer itself would be NULL. The XDP xmit callback also needs to synchronize with a device transitioning from open to close. This synchronization will happen via the GVE_PRIV_FLAGS_NAPI_ENABLED bit along with a synchronize_net() call, which waits for any RCU critical sections at call-time to complete.
