https://notcve.org/view.php?id=CVE-2022-48666
In the Linux kernel, the following vulnerability has been resolved: scsi: core: Fix a use-after-free There are two .exit_cmd_priv implementations. Both implementations use resources associated with the SCSI host. Make sure that these resources are still available when .exit_cmd_priv is called by waiting inside scsi_remove_host() until the tag set has been freed. This commit fixes the following use-after-free: ================================================================== BUG: KASAN: use-after-free in srp_exit_cmd_priv+0x27/0xd0 [ib_srp] Read of size 8 at addr ffff888100337000 by task multipathd/16727 Call Trace: <TASK> dump_stack_lvl+0x34/0x44 print_report.cold+0x5e/0x5db kasan_report+0xab/0x120 srp_exit_cmd_priv+0x27/0xd0 [ib_srp] scsi_mq_exit_request+0x4d/0x70 blk_mq_free_rqs+0x143/0x410 __blk_mq_free_map_and_rqs+0x6e/0x100 blk_mq_free_tag_set+0x2b/0x160 scsi_host_dev_release+0xf3/0x1a0 device_release+0x54/0xe0 kobject_put+0xa5/0x120 device_release+0x54/0xe0 kobject_put+0xa5/0x120 scsi_device_dev_release_usercontext+0x4c1/0x4e0 execute_in_process_context+0x23/0x90 device_release+0x54/0xe0 kobject_put+0xa5/0x120 scsi_disk_release+0x3f/0x50 device_release+0x54/0xe0 kobject_put+0xa5/0x120 disk_release+0x17f/0x1b0 device_release+0x54/0xe0 kobject_put+0xa5/0x120 dm_put_table_device+0xa3/0x160 [dm_mod] dm_put_device+0xd0/0x140 [dm_mod] free_priority_group+0xd8/0x110 [dm_multipath] free_multipath+0x94/0xe0 [dm_multipath] dm_table_destroy+0xa2/0x1e0 [dm_mod] __dm_destroy+0x196/0x350 [dm_mod] dev_remove+0x10c/0x160 [dm_mod] ctl_ioctl+0x2c2/0x590 [dm_mod] dm_ctl_ioctl+0x5/0x10 [dm_mod] __x64_sys_ioctl+0xb4/0xf0 dm_ctl_ioctl+0x5/0x10 [dm_mod] __x64_sys_ioctl+0xb4/0xf0 do_syscall_64+0x3b/0x90 entry_SYSCALL_64_after_hwframe+0x46/0xb0 En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: scsi: core: corrige un use-after-free Hay dos implementaciones de .exit_cmd_priv.

CVSS: 5.5EPSS: 0%CPEs: 4EXPL: 0CVE-2022-48660 – gpiolib: cdev: Set lineevent_state::irq after IRQ register successfully
https://notcve.org/view.php?id=CVE-2022-48660
In the Linux kernel, the following vulnerability has been resolved: gpiolib: cdev: Set lineevent_state::irq after IRQ register successfully When running gpio test on nxp-ls1028 platform with below command gpiomon --num-events=3 --rising-edge gpiochip1 25 There will be a warning trace as below: Call trace: free_irq+0x204/0x360 lineevent_free+0x64/0x70 gpio_ioctl+0x598/0x6a0 __arm64_sys_ioctl+0xb4/0x100 invoke_syscall+0x5c/0x130 ...... el0t_64_sync+0x1a0/0x1a4 The reason of this issue is that calling request_threaded_irq() function failed, and then lineevent_free() is invoked to release the resource. Since the lineevent_state::irq was already set, so the subsequent invocation of free_irq() would trigger the above warning call trace. To fix this issue, set the lineevent_state::irq after the IRQ register successfully. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: gpiolib: cdev: configure lineevent_state::irq después del registro IRQ con éxito Al ejecutar la prueba gpio en la plataforma nxp-ls1028 con el siguiente comando gpiomon --num-events=3 --rising-edge gpiochip1 25 Habrá un seguimiento de advertencia como se muestra a continuación: Seguimiento de llamada: free_irq+0x204/0x360 lineevent_free+0x64/0x70 gpio_ioctl+0x598/0x6a0 __arm64_sys_ioctl+0xb4/0x100 invoke_syscall+0x5c/0x130 ...... 0x1a0/0x1a4 El motivo de este problema es que falló la llamada a la función request_threaded_irq() y luego se invoca lineevent_free() para liberar el recurso. Dado que lineevent_state::irq ya estaba configurado, la invocación posterior de free_irq() activaría el seguimiento de llamada de advertencia anterior. • https://git.kernel.org/stable/c/468242724143a8e732f82f664b1e77432d149618 https://git.kernel.org/stable/c/657803b918e097e47d99d1489da83a603c36bcdd https://git.kernel.org/stable/c/97da736cd11ae73bdf2f5e21e24446b8349e0168 https://git.kernel.org/stable/c/b1489043d3b9004dd8d5a0357b08b5f0e6691c43 https://git.kernel.org/stable/c/69bef19d6b9700e96285f4b4e28691cda3dcd0d1 •
