https://notcve.org/view.php?id=CVE-2022-27950
In drivers/hid/hid-elo.c in the Linux kernel before 5.16.11, a memory leak exists for a certain hid_parse error condition. En el archivo drivers/hid/hid-elo.c en el kernel de Linux versiones anteriores a 5.16.11, se presenta una pérdida de memoria para una determinada condición de error hid_parse A memory leak flaw was found in elo_probe in drivers/hid/hid-elo.c in the Human Interface Devices (HID) in the Linux kernel. This issue allows an attacker to cause a denial of service when hid_parse() in elo_probe() fails. • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.16.11 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=817b8b9c5396d2b2d92311b46719aad5d3339dbe https://github.com/torvalds/linux/commit/817b8b9c5396d2b2d92311b46719aad5d3339dbe https://www.openwall.com/lists/oss-security/2022/03/13/1 https://access.redhat.com/security/cve/CVE-2022-27950 https://bugzilla.redhat.com/show_bug.cgi?id=2069408 • CWE-401: Missing Release of Memory after Effective Lifetime •
