  "description": "The Linux Kernel, the operating system core itself.\r\n\r\nSecurity Fix(es):\r\n\r\nopeneuler-linux-kernel-5.10.149-ext4_write_inline_data-kernel_bug-365020(CVE-2021-33631)\r\n\r\nAn issue was discovered in the Linux kernel through 6.3.8. A use-after-free was found in ravb_remove in drivers/net/ethernet/renesas/ravb_main.c.(CVE-2023-35827)\r\n\r\nAn out-of-bounds read vulnerability was found in smbCalcSize in fs/smb/client/netmisc.c in the Linux Kernel. This issue could allow a local attacker to crash the system or leak internal kernel information.(CVE-2023-6606)\r\n\r\nAn out-of-bounds read vulnerability was found in smb2_dump_detail in fs/smb/client/smb2ops.c in the Linux Kernel. This issue could allow a local attacker to crash the system or leak internal kernel information.(CVE-2023-6610)\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\nThe function nft_pipapo_walk did not skip inactive elements during set walk which could lead double deactivations of PIPAPO (Pile Packet Policies) elements, leading to use-after-free.\r\n\r\nWe recommend upgrading past commit 317eb9685095678f2c9f5a8189de698c5354316a.\r\n\r\n(CVE-2023-6817)\r\n\r\nA heap out-of-bounds write vulnerability in the Linux kernel's Performance Events system component can be exploited to achieve local privilege escalation.\r\n\r\nA perf_event's read_size can overflow, leading to an heap out-of-bounds increment or write in perf_read_group().\r\n\r\nWe recommend upgrading past commit 382c27f4ed28f803b1f1473ac2d8db0afc795a1b.\r\n\r\n(CVE-2023-6931)\r\n\r\nA use-after-free vulnerability in the Linux kernel's ipv4: igmp component can be exploited to achieve local privilege escalation.\r\n\r\nA race condition can be exploited to cause a timer be mistakenly registered on a RCU read locked object which is freed by another thread.\r\n\r\nWe recommend upgrading past commit e2b706c691905fe78468c361aaabc719d0a496f1.\r\n\r\n(CVE-2023-6932)",
