An issue was discovered in drivers/mtd/ubi/cdev.c in the Linux kernel 6.2. There is a divide-by-zero error in do_div, used indirectly by ctrl_cdev_ioctl, when mtd-greater than erasesize is 0. A flaw in the kernel Xen event handler can cause a deadlock with Xen console handling in unprivileged Xen guests. A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation.Due to a race condition between nf_tables netlink control plane transaction and nft_set element garbage collection, it is possible to underflow the reference counter causing a use-after-free vulnerability.We recommend upgrading past commit 3e91b0ebd994635df2346353322ac51ce84ce6d8. ipv4: fix null-deref in ipv4_link_failureNOTE: https://www.openwall.com/lists/oss-security/2023/10/02/8NOTE: https://git.kernel.org/linus/0113d9c9d1ccc07f5a3710dac4aa24b6d711278c A stack based out-of-bounds write flaw was found in the netfilter subsystem in the Linux kernel. If the expression length is a multiple of 4 , the `nft_exthdr_eval` family of functions writes 4 NULL bytes past the end of the `regs` argument, leading to stack corruption and potential information disclosure or a denial of service
