"text": "In the Linux kernel, the following vulnerability has been resolved:\n\npid: take a reference when initializing `cad_pid`\n\nDuring boot, kernel_init_freeable() initializes `cad_pid` to the init\ntask\u0027s struct pid. Later on, we may change `cad_pid` via a sysctl, and\nwhen this happens proc_do_cad_pid() will increment the refcount on the\nnew pid via get_pid(), and will decrement the refcount on the old pid\nvia put_pid(). As we never called get_pid() when we initialized\n`cad_pid`, we decrement a reference we never incremented, can therefore\nfree the init task\u0027s struct pid early. As there can be dangling\nreferences to the struct pid, we can later encounter a use-after-free\n(e.g. when delivering signals).\n\nThis was spotted when fuzzing v5.13-rc3 with Syzkaller, but seems to\nhave been around since the conversion of `cad_pid` to struct pid in\ncommit 9ec52099e4b8 (\"[PATCH] replace cad_pid by a struct pid\") from the\npre-KASAN stone age of v2.6.19.\n\nFix this by getting a reference to the init task\u0027s struct pid when we\nassign it to `cad_pid`.\n\nFull KASAN splat below.\n\n ==================================================================\n BUG: KASAN: use-after-free in ns_of_pid include/linux/pid.h:153 [inline]\n BUG: KASAN: use-after-free in task_active_pid_ns+0xc0/0xc8 kernel/pid.c:509\n Read of size 4 at addr ffff23794dda0004 by task syz-executor.0/273\n\n CPU: 1 PID: 273 Comm: syz-executor.0 Not tainted 5.12.0-00001-g9aef892b2d15 #1\n Hardware name: linux,dummy-virt (DT)\n Call trace:\n ns_of_pid include/linux/pid.h:153 [inline]\n task_active_pid_ns+0xc0/0xc8 kernel/pid.c:509\n do_notify_parent+0x308/0xe60 kernel/signal.c:1950\n exit_notify kernel/exit.c:682 [inline]\n do_exit+0x2334/0x2bd0 kernel/exit.c:845\n do_group_exit+0x108/0x2c8 kernel/exit.c:922\n get_signal+0x4e4/0x2a88 kernel/signal.c:2781\n do_signal arch/arm64/kernel/signal.c:882 [inline]\n do_notify_resume+0x300/0x970 arch/arm64/kernel/signal.c:936\n work_pending+0xc/0x2dc\n\n Allocated by task 0:\n slab_post_alloc_hook+0x50/0x5c0 mm/slab.h:516\n slab_alloc_node mm/slub.c:2907 [inline]\n slab_alloc mm/slub.c:2915 [inline]\n kmem_cache_alloc+0x1f4/0x4c0 mm/slub.c:2920\n alloc_pid+0xdc/0xc00 kernel/pid.c:180\n copy_process+0x2794/0x5e18 kernel/fork.c:2129\n kernel_clone+0x194/0x13c8 kernel/fork.c:2500\n kernel_thread+0xd4/0x110 kernel/fork.c:2552\n rest_init+0x44/0x4a0 init/main.c:687\n arch_call_rest_init+0x1c/0x28\n start_kernel+0x520/0x554 init/main.c:1064\n 0x0\n\n Freed by task 270:\n slab_free_hook mm/slub.c:1562 [inline]\n slab_free_freelist_hook+0x98/0x260 mm/slub.c:1600\n slab_free mm/slub.c:3161 [inline]\n kmem_cache_free+0x224/0x8e0 mm/slub.c:3177\n put_pid.part.4+0xe0/0x1a8 kernel/pid.c:114\n put_pid+0x30/0x48 kernel/pid.c:109\n proc_do_cad_pid+0x190/0x1b0 kernel/sysctl.c:1401\n proc_sys_call_handler+0x338/0x4b0 fs/proc/proc_sysctl.c:591\n proc_sys_write+0x34/0x48 fs/proc/proc_sysctl.c:617\n call_write_iter include/linux/fs.h:1977 [inline]\n new_sync_write+0x3ac/0x510 fs/read_write.c:518\n vfs_write fs/read_write.c:605 [inline]\n vfs_write+0x9c4/0x1018 fs/read_write.c:585\n ksys_write+0x124/0x240 fs/read_write.c:658\n __do_sys_write fs/read_write.c:670 [inline]\n __se_sys_write fs/read_write.c:667 [inline]\n __arm64_sys_write+0x78/0xb0 fs/read_write.c:667\n __invoke_syscall arch/arm64/kernel/syscall.c:37 [inline]\n invoke_syscall arch/arm64/kernel/syscall.c:49 [inline]\n el0_svc_common.constprop.1+0x16c/0x388 arch/arm64/kernel/syscall.c:129\n do_el0_svc+0xf8/0x150 arch/arm64/kernel/syscall.c:168\n el0_svc+0x28/0x38 arch/arm64/kernel/entry-common.c:416\n el0_sync_handler+0x134/0x180 arch/arm64/kernel/entry-common.c:432\n el0_sync+0x154/0x180 arch/arm64/kernel/entry.S:701\n\n The buggy address belongs to the object at ffff23794dda0000\n which belongs to the cache pid of size 224\n The buggy address is located 4 bytes inside of\n 224-byte region [ff\n---truncated---",

"text": "In the Linux kernel, the following vulnerability has been resolved:\n\ni2c: i801: Don\u0027t generate an interrupt on bus reset\n\nNow that the i2c-i801 driver supports interrupts, setting the KILL bit\nin a attempt to recover from a timed out transaction triggers an\ninterrupt. Unfortunately, the interrupt handler (i801_isr) is not\nprepared for this situation and will try to process the interrupt as\nif it was signaling the end of a successful transaction. In the case\nof a block transaction, this can result in an out-of-range memory\naccess.\n\nThis condition was reproduced several times by syzbot:\nhttps://syzkaller.appspot.com/bug?extid=ed71512d469895b5b34e\nhttps://syzkaller.appspot.com/bug?extid=8c8dedc0ba9e03f6c79e\nhttps://syzkaller.appspot.com/bug?extid=c8ff0b6d6c73d81b610e\nhttps://syzkaller.appspot.com/bug?extid=33f6c360821c399d69eb\nhttps://syzkaller.appspot.com/bug?extid=be15dc0b1933f04b043a\nhttps://syzkaller.appspot.com/bug?extid=b4d3fd1dfd53e90afd79\n\nSo disable interrupts while trying to reset the bus.

At the same time, the workqueue will do the\nflush_to_ldisc to pop data in a loop until there is no more data left.\nWhen the sender and workqueue running in different core, the sender sends\ndata fastly in full time which will result in workqueue doing work in loop\nfor a long time and occuring softlockup in flush_to_ldisc with kernel\nconfigured without preempt. So I add need_resched check and cond_resched\nin the flush_to_ldisc loop to avoid it.",

"text": "A flaw was found in the Linux kernel\u0027s x86/fpu module, which revolves around an issue with relying on user space for critical information regarding the xsave buffer. In the affected scenario, the expected size of the user space buffer is derived from user-controlled data, specifically, fx_sw-\u003exstate_size. By manipulating this value, an attacker could construct a malicious sigreturn frame where the indicated size is smaller than required by valid bits in fx_sw-\u003exfeatures. Furthermore, the attacker could unmap portions of the fpu buffer in the user space, rendering them inaccessible to xrstor.\r\n\r\nThis manipulation leads to a situation where xrstor repeatedly attempts to restore and access an unmapped area, causing a fault. However, the fault_in_readable function erroneously succeeds because the accessed region, buf + fx_sw-\u003exstate_size, remains within the mapped area. Consequently, the system enters a perpetual loop as xrstor continually retries the operation.",

"text": "This vulnerability, while technically significant due to its potential for exploitation, is classified as Low severity for several reasons. First, successful exploitation requires a precise set of conditions, including the ability to manipulate the fx_sw-\u003exstate_size parameter, which may not always be feasible. Additionally, the exploit\u0027s impact is limited to a specific subsystem (x86/fpu) within the Linux kernel, thereby reducing its overall scope and potential for widespread harm. Moreover, the loop resulting from the fault condition does not result in a system compromise or escalation of privileges but rather leads to a denial-of-service situation, which can be mitigated through a system reboot or other administrative actions.",

"text": "A flaw was found in the Linux kernel related to the Extensible Host Controller Interface (xHCI) subsystem, specifically how it handles certain events. The issue arises when the xHCI driver improperly handles isochronous (isoc) Babble and Buffer Overrun events. The vulnerability occurs because the xHCI driver incorrectly assumes that the xHC (host controller) has released its ownership of a multi-TRB (Transfer Request Block) TD (Transfer Descriptor) after reporting an error on an early TRB. This assumption leads to the premature release of the TD, allowing remaining TRBs to be freed or overwritten, which can cause system instability or crashes.",

"text": "A flaw was found in the Linux kernel. This vulnerability affects the ath9k wireless driver in the Linux kernel, specifically used with ath9k_htc devices. The issue arises from a race condition where certain initialization processes are incomplete when the system begins handling WiFi-related events. The problem occurs because the device is exposed to the USB subsystem before the ath9k driver finishes initializing critical data structures.\nThis can lead to NULL pointer dereferences, which cause system crashes, particularly when running specific commands or handling events during WiFi operations. A partial fix had been applied earlier to prevent one aspect of this issue, but further problems were identified. The final resolution was to delay all event handling in the ath9k_wmi_event_tasklet() function until initialization is fully complete, ensuring stability.",

"text": "In the Linux kernel, the following vulnerability has been resolved:\n\nUSB: core: Fix deadlock in port \"disable\" sysfs attribute\n\nThe show and store callback routines for the \"disable\" sysfs attribute\nfile in port.c acquire the device lock for the port\u0027s parent hub\ndevice. This can cause problems if another process has locked the hub\nto remove it or change its configuration:\n\n\tRemoving the hub or changing its configuration requires the\n\thub interface to be removed, which requires the port device\n\tto be removed, and device_del() waits until all outstanding\n\tsysfs attribute callbacks for the ports have returned. The\n\tlock can\u0027t be released until then.\n\n\tBut the disable_show() or disable_store() routine can\u0027t return\n\tuntil after it has acquired the lock.\n\nThe resulting deadlock can be avoided by calling\nsysfs_break_active_protection(). This will cause the sysfs core not\nto wait for the attribute\u0027s callback routine to return, allowing the\nremoval to proceed. The disadvantage is that after making this call,\nthere is no guarantee that the hub structure won\u0027t be deallocated at\nany moment. To prevent this, we have to acquire a reference to it\nfirst by calling hub_get().",

"text": "In the Linux kernel, the following vulnerability has been resolved:\n\nUSB: core: Fix deadlock in usb_deauthorize_interface()\n\nAmong the attribute file callback routines in\ndrivers/usb/core/sysfs.c, the interface_authorized_store() function is\nthe only one which acquires a device lock on an ancestor device: It\ncalls usb_deauthorize_interface(), which locks the interface\u0027s parent\nUSB device.\n\nThe will lead to deadlock if another process already owns that lock\nand tries to remove the interface, whether through a configuration\nchange or because the device has been disconnected. As part of the\nremoval procedure, device_del() waits for all ongoing sysfs attribute\ncallbacks to complete. But usb_deauthorize_interface() can\u0027t complete\nuntil the device lock has been released, and the lock won\u0027t be\nreleased until the removal has finished.\n\nThe mechanism provided by sysfs to prevent this kind of deadlock is\nto use the sysfs_break_active_protection() function, which tells sysfs\nnot to wait for the attribute callback.\n\nReported-and-tested by: Yue Sun \u003csamsun1006219@gmail.com\u003e\nReported by: xingwei lee \u003cxrivendell7@gmail.com\u003e",

At resume time it then tries to sync the write\npointer as it may have been updated by the firmware.\n\nIn the unusual event that no packets have been send on TID 0, the queue\nwill not have been allocated and this causes a crash.

"text": "In the Linux kernel, the following vulnerability has been resolved:\n\nUSB: usb-storage: Prevent divide-by-0 error in isd200_ata_command\n\nThe isd200 sub-driver in usb-storage uses the HEADS and SECTORS values\nin the ATA ID information to calculate cylinder and head values when\ncreating a CDB for READ or WRITE commands. The calculation involves\ndivision and modulus operations, which will cause a crash if either of\nthese values is 0. While this never happens with a genuine device, it\ncould happen with a flawed or subversive emulation, as reported by the\nsyzbot fuzzer.\n\nProtect against this possibility by refusing to bind to the device if\neither the ATA_ID_HEADS or ATA_ID_SECTORS value in the device\u0027s ID\ninformation is 0. This requires isd200_Initialization() to return a\nnegative error code when initialization fails; currently it always\nreturns 0 (even when there is an error).",
