From: George Stark <gnstark(a)salutedevices.com> mainline inclusion from mainline-v6.10-rc1 commit c382e2e3eccb6b7ca8c7aff5092c1668428e7de6 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAGRQX CVE: CVE-2024-42128 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- In this driver LEDs are registered using devm_led_classdev_register() so they are automatically unregistered after module's remove() is done. led_classdev_unregister() calls module's led_set_brightness() to turn off the LEDs and that callback uses mutex which was destroyed already in module's remove() so use devm API instead.

From: Filipe Manana <fdmanana(a)suse.com> mainline inclusion from mainline-v6.10-rc6 commit a7e4c6a3031c74078dba7fa36239d0f4fe476c53 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAGEN9 CVE: CVE-2024-41078 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- If during the quota disable we fail when cleaning the quota tree or when deleting the root from the root tree, we jump to the 'out' label without ever dropping the reference on the quota root, resulting in a leak of the root since fs_info->quota_root is no longer pointing to the root (we have set it to NULL just before those steps). Fix this by always doing a btrfs_put_root() call under the 'out' label. This is a problem that exists since qgroups were first added in 2012 by commit bed92eae26cc ("Btrfs: qgroup implementation and prototypes"), but back then we missed a kfree on the quota root and free_extent_buffer() calls on its root and commit root nodes, since back then roots were not yet reference counted.

linux-next inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAI2U3 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/… -------------------------------- The mbigen interrupt chip has its per node registers located in a contiguous region of page sized chunks. The code maps them into virtual address space as a contiguous region and determines the address of a node by using the node ID as index. mbigen chip |-----------------|------------|--------------| mgn_node_0 mgn_node_1 ... mgn_node_i |--------------| |--------------| |----------------------| [0x0000, 0x0x0FFF] [0x1000, 0x1FFF] [i*0x1000, (i+1)*0x1000 - 1] This works correctly up to 10 nodes, but then fails because the 11th's array slot is used for the MGN_CLEAR registers. mbigen chip |-----------|--------|--------|---------------|--------| mgn_node_0 mgn_node_1 ... mgn_clear_register ... mgn_node_i |-----------------| [0xA000, 0xAFFF] Skip the MGN_CLEAR register space when calculating the offset for node IDs greater than or equal to ten.

[PATCH OLK-6.6] ocfs2: strict bound check before memcmp in ocfs2_xattr_find_entry()

From: Ferry Meng <mengferry(a)linux.alibaba.com> mainline inclusion from mainline-v6.11-rc1 commit af77c4fc1871847b528d58b7fdafb4aa1f6a9262 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAG8SI CVE: CVE-2024-41016 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- xattr in ocfs2 maybe 'non-indexed', which saved with additional space requested. It's better to check if the memory is out of bound before memcmp, although this possibility mainly comes from crafted poisonous images.
