{"id":"AZL-52601","summary":"CVE-2024-50098 affecting package kernel for versions less than 6.6.64.2-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: ufs: core: Set SDEV_OFFLINE when UFS is shut down\n\nThere is a history of deadlock if reboot is performed at the beginning\nof booting. SDEV_QUIESCE was set for all LU's scsi_devices by UFS\nshutdown, and at that time the audio driver was waiting on\nblk_mq_submit_bio() holding a mutex_lock while reading the fw binary.\nAfter that, a deadlock issue occurred while audio driver shutdown was\nwaiting for mutex_unlock of blk_mq_submit_bio(). To solve this, set\nSDEV_OFFLINE for all LUs except WLUN, so that any I/O that comes down\nafter a UFS shutdown will return an error.\n\n[   31.907781]I[0:      swapper/0:    0]        1        130705007       1651079834      11289729804                0 D(   2) 3 ffffff882e208000 *             init [device_shutdown]\n[   31.907793]I[0:      swapper/0:    0] Mutex: 0xffffff8849a2b8b0: owner[0xffffff882e28cb00 kworker/6:0 :49]\n[   31.907806]I[0:      swapper/0:    0] Call trace:\n[   31.907810]I[0:      swapper/0:    0]  __switch_to+0x174/0x338\n[   31.907819]I[0:      swapper/0:    0]  __schedule+0x5ec/0x9cc\n[   31.907826]I[0:      swapper/0:    0]  schedule+0x7c/0xe8\n[   31.907834]I[0:      swapper/0:    0]  schedule_preempt_disabled+0x24/0x40\n[   31.907842]I[0:      swapper/0:    0]  __mutex_lock+0x408/0xdac\n[   31.907849]I[0:      swapper/0:    0]  __mutex_lock_slowpath+0x14/0x24\n[   31.907858]I[0:      swapper/0:    0]  mutex_lock+0x40/0xec\n[   31.907866]I[0:      swapper/0:    0]  device_shutdown+0x108/0x280\n[   31.907875]I[0:      swapper/0:    0]  kernel_restart+0x4c/0x11c\n[   31.907883]I[0:      swapper/0:    0]  __arm64_sys_reboot+0x15c/0x280\n[   31.907890]I[0:      swapper/0:    0]  invoke_syscall+0x70/0x158\n[   31.907899]I[0:      swapper/0:    0]  el0_svc_common+0xb4/0xf4\n[   31.907909]I[0:      swapper/0:    0]  do_el0_svc+0x2c/0xb0\n[   31.907918]I[0:      swapper/0:    0]  el0_svc+0x34/0xe0\n[   31.907928]I[0:      swapper/0:    0]  el0t_64_sync_handler+0x68/0xb4\n[   31.907937]I[0:      swapper/0:    0]  el0t_64_sync+0x1a0/0x1a4\n\n[   31.908774]I[0:      swapper/0:    0]       49                0         11960702      11236868007                0 D(   2) 6 ffffff882e28cb00 *      kworker/6:0 [__bio_queue_enter]\n[   31.908783]I[0:      swapper/0:    0] Call trace:\n[   31.908788]I[0:      swapper/0:    0]  __switch_to+0x174/0x338\n[   31.908796]I[0:      swapper/0:    0]  __schedule+0x5ec/0x9cc\n[   31.908803]I[0:      swapper/0:    0]  schedule+0x7c/0xe8\n[   31.908811]I[0:      swapper/0:    0]  __bio_queue_enter+0xb8/0x178\n[   31.908818]I[0:      swapper/0:    0]  blk_mq_submit_bio+0x194/0x67c\n[   31.908827]I[0:      swapper/0:    0]  __submit_bio+0xb8/0x19c","modified":"2026-04-01T05:17:52.664721Z","published":"2024-11-05T18:15:13Z","upstream":["CVE-2024-50098"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-50098"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.64.2-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-52601.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
