Due to the lengthy analysis of\nthe pcrypt_aead01 function call, I\u0026apos;ll describe the problem scenario\nusing a simplified model:\r\n\r\nSuppose there\u0026apos;s a user of padata named `user_function` that adheres to\nthe padata requirement of calling `padata_free_shell` after `serial()`\nhas been invoked, as demonstrated in the following code:\r\n\r\n```c\nstruct request {\n    struct padata_priv padata;\n    struct completion *done;\n};\r\n\r\nvoid parallel(struct padata_priv *padata) {\n    do_something();\n}\r\n\r\nvoid serial(struct padata_priv *padata) {\n    struct request *request = container_of(padata,\n    \t\t\t\tstruct request,\n\t\t\t\tpadata);\n    complete(request-\u0026gt;done);\n}\r\n\r\nvoid user_function() {\n    DECLARE_COMPLETION(done)\n    padata-\u0026gt;parallel = parallel;\n    padata-\u0026gt;serial = serial;\n    padata_do_parallel();\n    wait_for_completion(\u0026amp;done);\n    padata_free_shell();\n}\n```\r\n\r\nIn the corresponding padata.c file, there\u0026apos;s the following code:\r\n\r\n```c\nstatic void padata_serial_worker(struct work_struct *serial_work) {\n    ...\n    cnt = 0;\r\n\r\n    while (!list_empty(\u0026amp;local_list)) {\n        ...\n        padata-\u0026gt;serial(padata);\n        cnt++;\n    }\r\n\r\n    local_bh_enable();\r\n\r\n    if (refcount_sub_and_test(cnt, \u0026amp;pd-\u0026gt;refcnt))\n        padata_free_pd(pd);\n}\n```\r\n\r\nBecause of the high system load and the accumulation of unexecuted\nsoftirq at this moment, `local_bh_enable()` in padata takes longer\nto execute than usual. Subsequently, when accessing `pd-\u0026gt;refcnt`,\n`pd` has already been released by `padata_free_shell()`, resulting\nin a UAF issue with `pd-\u0026gt;refcnt`.\r\n\r\nThe fix is straightforward: add `refcount_dec_and_test` before calling\n`padata_free_pd` in `padata_free_shell`.(CVE-2023-52854)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nclk: mediatek: clk-mt7629: Add check for mtk_alloc_clk_data\r\n\r\nAdd the check for the return value of mtk_alloc_clk_data() in order to\navoid NULL pointer dereference.(CVE-2023-52858)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nhwmon: (axi-fan-control) Fix possible NULL pointer dereference\r\n\r\naxi_fan_control_irq_handler(), dependent on the private\naxi_fan_control_data structure, might be called before the hwmon\ndevice is registered.

It\nmaintains state of the event (is it enabled for the given instance?).\nOpening the \u0026quot;enable\u0026quot; file gets a reference to the event \u0026quot;file\u0026quot; descriptor\nvia the open file descriptor. When the kprobe event is deleted, the file is\nalso deleted from the tracefs system which also frees the event \u0026quot;file\u0026quot;\ndescriptor.\r\n\r\nBut as the tracefs file is still opened by user space, it will not be\ntotally removed until the final dput() is called on it. But this is not\ntrue with the event \u0026quot;file\u0026quot; descriptor that is already freed. If the user\ndoes a write to or simply closes the file descriptor it will reference the\nevent \u0026quot;file\u0026quot; descriptor that was just freed, causing a use-after-free bug.\r\n\r\nTo solve this, add a ref count to the event \u0026quot;file\u0026quot; descriptor as well as a\nnew flag called \u0026quot;FREED\u0026quot;. The \u0026quot;file\u0026quot; will not be freed until the last\nreference is released.

Fill_meta_index() is called to allocate (via empty_meta_index())\n   and fill a metadata index.  It however suffers a data read error\n   and aborts, invalidating the newly returned empty metadata index.\n   It does this by setting the inode number of the index to zero,\n   which means unused (zero is not a valid inode number).\r\n\r\n2. When fill_meta_index() is subsequently called again on another\n   read operation, locate_meta_index() returns the previous index\n   because it matches the inode number of 0.  Because this index\n   has been returned it is expected to have been filled, and because\n   it hasn\u0026apos;t been, an out of bounds access is performed.\r\n\r\nThis patch adds a sanity check which checks that the inode number\nis not zero when the inode is created and returns -EINVAL if it is.\r\n\r\n[phillip@squashfs.org.uk: whitespace fix]\n  Link: https://lkml.kernel.org/r/20240409204723.446925-1-phillip@squashfs.org.uk(CVE-2024-26982)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nfs: sysfs: Fix reference leak in sysfs_break_active_protection()\r\n\r\nThe sysfs_break_active_protection() routine has an obvious reference\nleak in its error path.
