Vulnerabilities 10
-
High 7.8CVE-2023-35001 Public exploit
Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability
Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; nft_byteorder poorly handled vm register contents when CAP_NET_ADMIN is in any user or network namespace
-
High 7.8
Out-of-bounds write in Linux kernel's net/sched: sch_qfq component
An out-of-bounds write vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited to achieve local privilege escalation. The qfq_change_agg() function in net/sched/sch_qfq.c allows an out-of-bounds write because lmax is updated accordin…

High 7.8CVE-2023-3776 Public exploit
Use-after-free in Linux kernel's net/sched: cls_fw component
A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to achieve local privilege escalation. If tcf_change_indev() fails, fw_set_parms() will immediately return an error after incrementing or decrementing the refere…
-
High 7.8
Use-after-free in Linux kernel's net/sched: cls_route component
A use-after-free vulnerability in the Linux kernel's net/sched: cls_route component can be exploited to achieve local privilege escalation. When route4_change() is called on an existing filter, the whole tcf_result struct is always copied into the new instanc…

Kernel: vmxnet3: use-after-free in vmxnet3_rq_alloc_rx_buf()
A use-after-free flaw was found in vmxnet3_rq_alloc_rx_buf in drivers/net/vmxnet3/vmxnet3_drv.c in VMware's vmxnet3 ethernet NIC driver in the Linux Kernel. This issue could allow a local attacker to crash the system due to a double-free while cleaning up vmx…

Kernel: xfrm: null pointer dereference in xfrm_update_ae_params()
A flaw was found in the Linux kernel’s IP framework for transforming packets (XFRM subsystem). This issue may allow a malicious user with CAP_NET_ADMIN privileges to directly dereference a NULL pointer in xfrm_update_ae_params(), leading to a possible kernel …
