  "description": "The Linux Kernel, the operating system core itself.\r\n\r\nSecurity Fix(es):\r\n\r\nA use-after-free flaw was found in xgene_hwmon_remove in drivers/hwmon/xgene-hwmon.c in the Hardware Monitoring Linux Kernel Driver (xgene-hwmon). This flaw could allow a local attacker to crash the system due to a race problem. This vulnerability could even lead to a kernel information leak problem.(CVE-2023-1855)\r\n\r\nA use-after-free flaw was found in ndlc_remove in drivers/nfc/st-nci/ndlc.c in the Linux Kernel. This flaw could allow an attacker to crash the system due to a race problem.(CVE-2023-1990)\r\n\r\nA use-after-free vulnerability in the Linux Kernel io_uring system can be exploited to achieve local privilege escalation.\r\n\r\nThe io_file_get_fixed function lacks the presence of ctx->uring_lock which can lead to a Use-After-Free vulnerability due a race condition with fixed files getting unregistered.\r\n\r\nWe recommend upgrading past commit da24142b1ef9fd5d36b76e36bab328a5b27523e8.\r\n\r\n(CVE-2023-1872)\r\n\r\nA race condition was found in the Linux kernel's RxRPC network protocol, within the processing of RxRPC bundles. This issue results from the lack of proper locking when performing operations on an object. This may allow an attacker to escalate privileges and execute arbitrary code in the context of the kernel.(CVE-2023-2006)\r\n\r\nThe Linux kernel before 6.2.9 has a race condition and resultant use-after-free in drivers/power/supply/da9150-charger.c if a physically proximate attacker unplugs a device.(CVE-2023-30772)",
