{"id":"DEBIAN-CVE-2024-56553","details":"In the Linux kernel, the following vulnerability has been resolved:  binder: fix memleak of proc-\u003edelivered_freeze  If a freeze notification is cleared with BC_CLEAR_FREEZE_NOTIFICATION before calling binder_freeze_notification_done(), then it is detached from its reference (e.g. ref-\u003efreeze) but the work remains queued in proc-\u003edelivered_freeze. This leads to a memory leak when the process exits as any pending entries in proc-\u003edelivered_freeze are not freed:    unreferenced object 0xffff38e8cfa36180 (size 64):     comm \"binder-util\", pid 655, jiffies 4294936641     hex dump (first 32 bytes):       b8 e9 9e c8 e8 38 ff ff b8 e9 9e c8 e8 38 ff ff  .....8.......8..       0b 00 00 00 00 00 00 00 3c 1f 4b 00 00 00 00 00  ........\u003c.K.....     backtrace (crc 95983b32):       [\u003c000000000d0582cf\u003e] kmemleak_alloc+0x34/0x40       [\u003c000000009c99a513\u003e] __kmalloc_cache_noprof+0x208/0x280       [\u003c00000000313b1704\u003e] binder_thread_write+0xdec/0x439c       [\u003c000000000cbd33bb\u003e] binder_ioctl+0x1b68/0x22cc       [\u003c000000002bbedeeb\u003e] __arm64_sys_ioctl+0x124/0x190       [\u003c00000000b439adee\u003e] invoke_syscall+0x6c/0x254       [\u003c00000000173558fc\u003e] el0_svc_common.constprop.0+0xac/0x230       [\u003c0000000084f72311\u003e] do_el0_svc+0x40/0x58       [\u003c000000008b872457\u003e] el0_svc+0x38/0x78       [\u003c00000000ee778653\u003e] el0t_64_sync_handler+0x120/0x12c       [\u003c00000000a8ec61bf\u003e] el0t_64_sync+0x190/0x194  This patch fixes the leak by ensuring that any pending entries in proc-\u003edelivered_freeze are freed during binder_deferred_release().","modified":"2026-09-15T09:03:16.810112676Z","published":"2024-12-27T15:15:14.073Z","upstream":["CVE-2024-56553"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2024-56553"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.12.5-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-56553.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.12.5-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-56553.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
