{"id":"CVE-2023-53090","summary":"drm/amdkfd: Fix an illegal memory access","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amdkfd: Fix an illegal memory access\n\nIn the kfd_wait_on_events() function, the kfd_event_waiter structure is\nallocated by alloc_event_waiters(), but the event field of the waiter\nstructure is not initialized; When copy_from_user() fails in the\nkfd_wait_on_events() function, it will enter exception handling to\nrelease the previously allocated memory of the waiter structure;\nDue to the event field of the waiters structure being accessed\nin the free_waiters() function, this results in illegal memory access\nand system crash, here is the crash log:\n\nlocalhost kernel: RIP: 0010:native_queued_spin_lock_slowpath+0x185/0x1e0\nlocalhost kernel: RSP: 0018:ffffaa53c362bd60 EFLAGS: 00010082\nlocalhost kernel: RAX: ff3d3d6bff4007cb RBX: 0000000000000282 RCX: 00000000002c0000\nlocalhost kernel: RDX: ffff9e855eeacb80 RSI: 000000000000279c RDI: ffffe7088f6a21d0\nlocalhost kernel: RBP: ffffe7088f6a21d0 R08: 00000000002c0000 R09: ffffaa53c362be64\nlocalhost kernel: R10: ffffaa53c362bbd8 R11: 0000000000000001 R12: 0000000000000002\nlocalhost kernel: R13: ffff9e7ead15d600 R14: 0000000000000000 R15: ffff9e7ead15d698\nlocalhost kernel: FS:  0000152a3d111700(0000) GS:ffff9e855ee80000(0000) knlGS:0000000000000000\nlocalhost kernel: CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\nlocalhost kernel: CR2: 0000152938000010 CR3: 000000044d7a4000 CR4: 00000000003506e0\nlocalhost kernel: Call Trace:\nlocalhost kernel: _raw_spin_lock_irqsave+0x30/0x40\nlocalhost kernel: remove_wait_queue+0x12/0x50\nlocalhost kernel: kfd_wait_on_events+0x1b6/0x490 [hydcu]\nlocalhost kernel: ? ftrace_graph_caller+0xa0/0xa0\nlocalhost kernel: kfd_ioctl+0x38c/0x4a0 [hydcu]\nlocalhost kernel: ? kfd_ioctl_set_trap_handler+0x70/0x70 [hydcu]\nlocalhost kernel: ? kfd_ioctl_create_queue+0x5a0/0x5a0 [hydcu]\nlocalhost kernel: ? ftrace_graph_caller+0xa0/0xa0\nlocalhost kernel: __x64_sys_ioctl+0x8e/0xd0\nlocalhost kernel: ? syscall_trace_enter.isra.18+0x143/0x1b0\nlocalhost kernel: do_syscall_64+0x33/0x80\nlocalhost kernel: entry_SYSCALL_64_after_hwframe+0x44/0xa9\nlocalhost kernel: RIP: 0033:0x152a4dff68d7\n\nAllocate the structure with kcalloc, and remove redundant 0-initialization\nand a redundant loop condition check.","modified":"2026-04-03T13:14:38.669814Z","published":"2025-05-02T15:55:36.164Z","related":["SUSE-SU-2025:01918-1","SUSE-SU-2025:01966-1","SUSE-SU-2025:02173-1","SUSE-SU-2025:02262-1","SUSE-SU-2025:02334-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53090.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2fece63b55c5d74cd6f5de51159e2cde37e10555"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4fc8fff378b2f2039f2a666d9f8c570f4e58352c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5a3fb3b745af0ce46ec2e0c8e507bae45b937334"},{"type":"WEB","url":"https://git.kernel.org/stable/c/61f306f8df0d5559659c5578cf6d95236bcdcb25"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6936525142a015e854d0a23e9ad9ea0a28b3843d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bbf5eada4334a96e3a204b2307ff5b14dc380b0b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d9923e7214a870b312bf61f6a89c7554d0966985"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53090.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-53090"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4a488a7ad71401169cecee75dc94bcce642e2c53"},{"fixed":"5a3fb3b745af0ce46ec2e0c8e507bae45b937334"},{"fixed":"bbf5eada4334a96e3a204b2307ff5b14dc380b0b"},{"fixed":"6936525142a015e854d0a23e9ad9ea0a28b3843d"},{"fixed":"2fece63b55c5d74cd6f5de51159e2cde37e10555"},{"fixed":"d9923e7214a870b312bf61f6a89c7554d0966985"},{"fixed":"61f306f8df0d5559659c5578cf6d95236bcdcb25"},{"fixed":"4fc8fff378b2f2039f2a666d9f8c570f4e58352c"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-53090.json"}}],"schema_version":"1.7.5"}
