{"id":"DEBIAN-CVE-2022-50556","details":"In the Linux kernel, the following vulnerability has been resolved:  drm: Fix potential null-ptr-deref due to drmm_mode_config_init()  drmm_mode_config_init() will call drm_mode_create_standard_properties() and won't check the ret value. When drm_mode_create_standard_properties() failed due to alloc, property will be a NULL pointer and may causes the null-ptr-deref. Fix the null-ptr-deref by adding the ret value check.  Found null-ptr-deref while testing insert module bochs: general protection fault, probably for non-canonical address     0xdffffc000000000c: 0000 [#1] SMP KASAN PTI KASAN: null-ptr-deref in range [0x0000000000000060-0x0000000000000067] CPU: 3 PID: 249 Comm: modprobe Not tainted 6.1.0-rc1+ #364 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.15.0-0-g2dd4b9b3f840-prebuilt.qemu.org 04/01/2014 RIP: 0010:drm_object_attach_property+0x73/0x3c0 [drm] Call Trace:  \u003cTASK\u003e  __drm_connector_init+0xb6c/0x1100 [drm]  bochs_pci_probe.cold.11+0x4cb/0x7fe [bochs]  pci_device_probe+0x17d/0x340  really_probe+0x1db/0x5d0  __driver_probe_device+0x1e7/0x250  driver_probe_device+0x4a/0x120  __driver_attach+0xcd/0x2c0  bus_for_each_dev+0x11a/0x1b0  bus_add_driver+0x3d7/0x500  driver_register+0x18e/0x320  do_one_initcall+0xc4/0x3e0  do_init_module+0x1b4/0x630  load_module+0x5dca/0x7230  __do_sys_finit_module+0x100/0x170  do_syscall_64+0x3f/0x90  entry_SYSCALL_64_after_hwframe+0x63/0xcd RIP: 0033:0x7ff65af9f839","modified":"2026-09-01T16:05:35.639620636Z","published":"2025-10-22T14:15:39.673Z","upstream":["CVE-2022-50556"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2022-50556"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.20-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-50556.json"}},{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.20-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-50556.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.20-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-50556.json"}}],"schema_version":"1.9.0"}
