| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2024-08-17 | CVE-2024-43823 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: PCI: keystone: Fix NULL pointer dereference in case of DT error in ks_pcie_setup_rc_app_regs() If IORESOURCE_MEM is not provided in Device Tree due to any error, resource_list_first_type() will return NULL and pci_parse_request_of_pci_ranges() will just emit a warning. This will cause a NULL pointer dereference. | 5.5 |
| 2024-08-17 | CVE-2024-43824 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: PCI: endpoint: pci-epf-test: Make use of cached 'epc_features' in pci_epf_test_core_init() Instead of getting the epc_features from pci_epc_get_features() API, use the cached pci_epf_test::epc_features value to avoid the NULL check. | 5.5 |
| 2024-08-17 | CVE-2024-43828 | Infinite Loop vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ext4: fix infinite loop when replaying fast_commit When doing fast_commit replay an infinite loop may occur due to an uninitialized extent_status struct. | 5.5 |
| 2024-08-17 | CVE-2024-43853 | Use After Free vulnerability in Linux Kernel 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. | 5.5 |
| 2024-08-17 | CVE-2024-43854 | Memory Leak vulnerability in Linux Kernel 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. | 5.5 |
| 2024-08-17 | CVE-2024-43855 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: md: fix deadlock between mddev_suspend and flush bio Deadlock occurs when mddev is being suspended while some flush bio is in progress. | 5.5 |
| 2024-08-17 | CVE-2024-43856 | Allocation of Resources Without Limits or Throttling vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: dma: fix call order in dmam_free_coherent dmam_free_coherent() frees a DMA allocation, which makes the freed vaddr available for reuse, then calls devres_destroy() to remove and free the data structure used to track the DMA allocation. | 5.5 |
| 2024-08-17 | CVE-2024-43858 | Improper Validation of Array Index vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: jfs: Fix array-index-out-of-bounds in diFree | 7.8 |
| 2024-08-17 | CVE-2024-43859 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: f2fs: fix to truncate preallocated blocks in f2fs_file_open() chenyuwen reports a f2fs bug as below: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000011 fscrypt_set_bio_crypt_ctx+0x78/0x1e8 f2fs_grab_read_bio+0x78/0x208 f2fs_submit_page_read+0x44/0x154 f2fs_get_read_data_page+0x288/0x5f4 f2fs_get_lock_data_page+0x60/0x190 truncate_partial_data_page+0x108/0x4fc f2fs_do_truncate_blocks+0x344/0x5f0 f2fs_truncate_blocks+0x6c/0x134 f2fs_truncate+0xd8/0x200 f2fs_iget+0x20c/0x5ac do_garbage_collect+0x5d0/0xf6c f2fs_gc+0x22c/0x6a4 f2fs_disable_checkpoint+0xc8/0x310 f2fs_fill_super+0x14bc/0x1764 mount_bdev+0x1b4/0x21c f2fs_mount+0x20/0x30 legacy_get_tree+0x50/0xbc vfs_get_tree+0x5c/0x1b0 do_new_mount+0x298/0x4cc path_mount+0x33c/0x5fc __arm64_sys_mount+0xcc/0x15c invoke_syscall+0x60/0x150 el0_svc_common+0xb8/0xf8 do_el0_svc+0x28/0xa0 el0_svc+0x24/0x84 el0t_64_sync_handler+0x88/0xec It is because inode.i_crypt_info is not initialized during below path: - mount - f2fs_fill_super - f2fs_disable_checkpoint - f2fs_gc - f2fs_iget - f2fs_truncate So, let's relocate truncation of preallocated blocks to f2fs_file_open(), after fscrypt_file_open(). | 5.5 |
| 2024-08-17 | CVE-2024-43860 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: remoteproc: imx_rproc: Skip over memory region when node value is NULL In imx_rproc_addr_init() "nph = of_count_phandle_with_args()" just counts number of phandles. | 5.5 |
