In the Linux kernel, the following vulnerability has been resolved: block: initialize integrity buffer to zero before writing it to media Metadata added by bio_integrity_prep is using plain kmalloc, which leads to random kernel memory being written media. For PI metadata this is limited to the app tag that isn't used by kernel generated metadata, but for non-PI metadata the entire buffer leaks kernel memory. Fix this by adding the __GFP_ZERO flag to allocations for writes. • https://git.kernel.org/stable/c/7ba1ba12eeef0aa7113beb16410ef8b7c748e18b https://git.kernel.org/stable/c/9f4af4cf08f9a0329ade3d938f55d2220c40d0a6 https://git.kernel.org/stable/c/129f95948a96105c1fad8e612c9097763e88ac5f https://git.kernel.org/stable/c/3fd11fe4f20756b4c0847f755a64cd96f8c6a005 https://git.kernel.org/stable/c/cf6b45ea7a8df0f61bded1dc4a8561ac6ad143d2 https://git.kernel.org/stable/c/d418313bd8f55c079a7da12651951b489a638ac1 https://git.kernel.org/stable/c/23a19655fb56f241e592041156dfb1c6d04da644 https://git.kernel.org/stable/c/ebc0e91ba76dc6544fff9f5b66408b198 • CWE-401: Missing Release of Memory after Effective Lifetime •

In the Linux kernel, the following vulnerability has been resolved: cgroup/cpuset: Prevent UAF in proc_cpuset_show() An UAF can happen when /proc/cpuset is read as reported in [1]. This can be reproduced by the following methods: 1.add an mdelay(1000) before acquiring the cgroup_lock In the cgroup_path_ns function. 2.$cat /proc/<pid>/cpuset repeatly. 3.$mount -t cgroup -o cpuset cpuset /sys/fs/cgroup/cpuset/ $umount /sys/fs/cgroup/cpuset/ repeatly. The race that cause this bug can be shown as below: (umount) | (cat /proc/<pid>/cpuset) css_release | proc_cpuset_show css_release_work_fn | css = task_get_css(tsk, cpuset_cgrp_id); css_free_rwork_fn | cgroup_path_ns(css->cgroup, ...); cgroup_destroy_root | mutex_lock(&cgroup_mutex); rebind_subsystems | cgroup_free_root | | // cgrp was freed, UAF | cgroup_path_ns_locked(cgrp,..); When the cpuset is initialized, the root node top_cpuset.css.cgrp will point to &cgrp_dfl_root.cgrp. • https://git.kernel.org/stable/c/a79a908fd2b080977b45bf103184b81c9d11ad07 https://git.kernel.org/stable/c/27d6dbdc6485d68075a0ebf8544d6425c1ed84bb https://git.kernel.org/stable/c/10aeaa47e4aa2432f29b3e5376df96d7dac5537a https://git.kernel.org/stable/c/688325078a8b5badd6e07ae22b27cd04e9947aec https://git.kernel.org/stable/c/4e8d6ac8fc9f843e940ab7389db8136634e07989 https://git.kernel.org/stable/c/29a8d4e02fd4840028c38ceb1536cc8f82a257d4 https://git.kernel.org/stable/c/96226fbed566f3f686f53a489a29846f2d538080 https://git.kernel.org/stable/c/29ac1d238b3bf126af36037df80d7ecc4 •

In the Linux kernel, the following vulnerability has been resolved: hwmon: (ltc2991) re-order conditions to fix off by one bug LTC2991_T_INT_CH_NR is 4. The st->temp_en[] array has LTC2991_MAX_CHANNEL (4) elements. Thus if "channel" is equal to LTC2991_T_INT_CH_NR then we have read one element beyond the end of the array. Flip the conditions around so that we check if "channel" is valid before using it as an array index. • https://git.kernel.org/stable/c/2b9ea4262ae9114b0b86ac893b4d6175d8520001 https://git.kernel.org/stable/c/c180311c0a520692e2d0e9ca44dcd6c2ff1b41c4 https://git.kernel.org/stable/c/99bf7c2eccff82760fa23ce967cc67c8c219c6a6 •

In the Linux kernel, the following vulnerability has been resolved: soc: xilinx: rename cpu_number1 to dummy_cpu_number The per cpu variable cpu_number1 is passed to xlnx_event_handler as argument "dev_id", but it is not used in this function. So drop the initialization of this variable and rename it to dummy_cpu_number. This patch is to fix the following call trace when the kernel option CONFIG_DEBUG_ATOMIC_SLEEP is enabled: BUG: sleeping function called from invalid context at include/linux/sched/mm.h:274 in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 1, name: swapper/0 preempt_count: 1, expected: 0 CPU: 0 PID: 1 Comm: swapper/0 Not tainted 6.1.0 #53 Hardware name: Xilinx Versal vmk180 Eval board rev1.1 (QSPI) (DT) Call trace: dump_backtrace+0xd0/0xe0 show_stack+0x18/0x40 dump_stack_lvl+0x7c/0xa0 dump_stack+0x18/0x34 __might_resched+0x10c/0x140 __might_sleep+0x4c/0xa0 __kmem_cache_alloc_node+0xf4/0x168 kmalloc_trace+0x28/0x38 __request_percpu_irq+0x74/0x138 xlnx_event_manager_probe+0xf8/0x298 platform_probe+0x68/0xd8 • https://git.kernel.org/stable/c/01946c3c83b2279fec685abc83f0d7b0468851db https://git.kernel.org/stable/c/4722924e7a6225ebf7b09bd7ac5fafc6e73bd4f8 https://git.kernel.org/stable/c/daed80ed07580e5adc0e6d8bc79933a35154135a https://git.kernel.org/stable/c/548bdbbdcd355f5a844c7122c83c9aab115051fa https://git.kernel.org/stable/c/a5e507fadab76393cbc12344ebd65a417a09aa46 https://git.kernel.org/stable/c/a96e60a6ea6818fd37b1853283a512c49af38cf5 https://git.kernel.org/stable/c/f762acdaff9e54688be16e6c832c73a61533c1df https://git.kernel.org/stable/c/4a95449dd975e2ea6629a034f3e74b46c •
