[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.

[PATCH openEuler-1.0-LTS] drm: adv7511: Fix use-after-free in adv7533_attach_dsi()

From: Biju Das <biju.das.jz(a)bp.renesas.com> stable inclusion from stable-v5.10.234 commit acec80d9f126cd3fa764bbe3d96bc0cb5cd2b087 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBID2S CVE: CVE-2024-57887 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 81adbd3ff21c1182e06aa02c6be0bfd9ea02d8e8 ] The host_node pointer was assigned and freed in adv7533_parse_dt(), and later, adv7533_attach_dsi() uses the same.

[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.

[PATCH OLK-6.6] gve: guard XSK operations on the existence of 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 771d66f2bd8c4dba1286a9163ab982cecd825718 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBJ6P5 CVE: CVE-2024-57933 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 40338d7987d810fcaa95c500b1068a52b08eec9b upstream. This patch predicates the enabling and disabling of XSK pools on the existence of queues. As it stands, if the interface is down, disabling or enabling XSK pools would result in a crash, as the RX queue pointer would be NULL. XSK pool registration will occur as part of the next interface up. Similarly, xsk_wakeup needs be guarded against queues disappearing while the function is executing, so a check against the GVE_PRIV_FLAGS_NAPI_ENABLED flag is added to synchronize with the disabling of the bit and the synchronize_net() in gve_turndown.

The root cause is a buggy MPTCP option len computation in some circumstances: the ADD_ADDR option should be mutually exclusive with DSS since the blamed commit. Still, mptcp_established_options_add_addr() tries to set the relevant info in mptcp_out_options, if the remaining space is large enough even when DSS is present. Since the ADD_ADDR infos and the DSS share the same union fields, adding first corrupts the latter. In the worst-case scenario, such corruption increases the DSS binary layout, exceeding the computed length and possibly overwriting the skb shared info. Address the issue by enforcing mutual exclusion in mptcp_established_options_add_addr(), too.
