"description": "The Linux Kernel, the operating system core itself.\r\n\r\nSecurity Fix(es):\r\n\r\nAn issue was discovered in the Linux kernel through 6.0.9. drivers/media/dvb-core/dvbdev.c has a use-after-free, related to dvb_register_device dynamically allocating fops.(CVE-2022-45884)\r\n\r\nRejected reason: DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2023-35823. Reason: This candidate is a reservation duplicate of CVE-2023-35823. Notes: All CVE users should reference CVE-2023-35823 instead of this candidate. All references and descriptions in this candidate have been removed to prevent accidental usage.(CVE-2023-3327)\r\n\r\nA race condition was found in the QXL driver in the Linux kernel. The qxl_mode_dumb_create() function dereferences the qobj returned by the qxl_gem_object_create_with_handle(), but the handle is the only one holding a reference to it. This flaw allows an attacker to guess the returned handle value and trigger a use-after-free issue, potentially leading to a denial of service or privilege escalation.(CVE-2023-39198)\r\n\r\nA use-after-free vulnerability in the Linux kernel's net/sched: sch_hfsc (HFSC qdisc traffic control) component can be exploited to achieve local privilege escalation.\r\n\r\nIf a class with a link-sharing curve (i.e. with the HFSC_FSC flag set) has a parent without a link-sharing curve, then init_vf() will call vttree_insert() on the parent, but vttree_remove() will be skipped in update_vf(). This leaves a dangling pointer that can cause a use-after-free.\r\n\r\nWe recommend upgrading past commit b3d26c5702c7d6c45456326e56d2ccf3f103e60f.\r\n\r\n(CVE-2023-4623)\r\n\r\nA use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation.\r\n\r\nAddition and removal of rules from chain bindings within the same transaction causes leads to use-after-free.\r\n\r\nWe recommend upgrading past commit f15f29fd4779be8a418b66e9d52979bb6d6c2325.\r\n\r\n(CVE-2023-5197)",
