{"id":"DEBIAN-CVE-2022-49800","details":"In the Linux kernel, the following vulnerability has been resolved:  tracing: Fix memory leak in test_gen_synth_cmd() and test_empty_synth_event()  test_gen_synth_cmd() only free buf in fail path, hence buf will leak when there is no failure. Add kfree(buf) to prevent the memleak. The same reason and solution in test_empty_synth_event().  unreferenced object 0xffff8881127de000 (size 2048):   comm \"modprobe\", pid 247, jiffies 4294972316 (age 78.756s)   hex dump (first 32 bytes):     20 67 65 6e 5f 73 79 6e 74 68 5f 74 65 73 74 20   gen_synth_test     20 70 69 64 5f 74 20 6e 65 78 74 5f 70 69 64 5f   pid_t next_pid_   backtrace:     [\u003c000000004254801a\u003e] kmalloc_trace+0x26/0x100     [\u003c0000000039eb1cf5\u003e] 0xffffffffa00083cd     [\u003c000000000e8c3bc8\u003e] 0xffffffffa00086ba     [\u003c00000000c293d1ea\u003e] do_one_initcall+0xdb/0x480     [\u003c00000000aa189e6d\u003e] do_init_module+0x1cf/0x680     [\u003c00000000d513222b\u003e] load_module+0x6a50/0x70a0     [\u003c000000001fd4d529\u003e] __do_sys_finit_module+0x12f/0x1c0     [\u003c00000000b36c4c0f\u003e] do_syscall_64+0x3f/0x90     [\u003c00000000bbf20cf3\u003e] entry_SYSCALL_64_after_hwframe+0x63/0xcd unreferenced object 0xffff8881127df000 (size 2048):   comm \"modprobe\", pid 247, jiffies 4294972324 (age 78.728s)   hex dump (first 32 bytes):     20 65 6d 70 74 79 5f 73 79 6e 74 68 5f 74 65 73   empty_synth_tes     74 20 20 70 69 64 5f 74 20 6e 65 78 74 5f 70 69  t  pid_t next_pi   backtrace:     [\u003c000000004254801a\u003e] kmalloc_trace+0x26/0x100     [\u003c00000000d4db9a3d\u003e] 0xffffffffa0008071     [\u003c00000000c31354a5\u003e] 0xffffffffa00086ce     [\u003c00000000c293d1ea\u003e] do_one_initcall+0xdb/0x480     [\u003c00000000aa189e6d\u003e] do_init_module+0x1cf/0x680     [\u003c00000000d513222b\u003e] load_module+0x6a50/0x70a0     [\u003c000000001fd4d529\u003e] __do_sys_finit_module+0x12f/0x1c0     [\u003c00000000b36c4c0f\u003e] do_syscall_64+0x3f/0x90     [\u003c00000000bbf20cf3\u003e] entry_SYSCALL_64_after_hwframe+0x63/0xcd","modified":"2026-09-01T20:04:56.378185491Z","published":"2025-05-01T15:16:03.303Z","upstream":["CVE-2022-49800"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2022-49800"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0.10-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2022-49800.json"}},{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0.10-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2022-49800.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0.10-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2022-49800.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"}]}
