script_tag(name:"insight", value:"A use-after-free flaw was found in net/sched/cls_fw.c in classifiers (cls_fw, cls_u32, and cls_route) in the Linux Kernel. This flaw allows a local attacker to perform a local privilege escalation due to incorrect handling of the existing filter, leading to a kernel information leak issue.(CVE-2023-4128)
A flaw was found in the Linux kernel's TUN/TAP functionality. This issue could allow a local user to bypass network filters and gain unauthorized access to some resources. The original patches fixing CVE-2023-1076 are incorrect or incomplete. The problem is that the following upstream commits - a096ccca6e50 ('tun: tun_chr_open(): correctly initialize socket uid'), - 66b2c338adce ('tap: tap_open(): correctly initialize socket uid'), pass 'inode->i_uid' to sock_init_data_uid() as the last parameter and that turns out to not be accurate.(CVE-2023-4194)
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 reference counter in tcf_bind_filter(). If an attacker can control the reference counter and set it to zero, they can cause the reference to be freed, leading to a use-after-free vulnerability.We recommend upgrading past commit 0323bce598eea038714f941ce2b22541c46d488f.(CVE-2023-3776)
A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to achieve local privilege escalation.If tcf_change_indev() fails, u32_set_parms() will immediately return an error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can control the reference counter and set it to zero, they can cause the reference to be freed, leading to a use-after-free vulnerability.We recommend upgrading past commit 04c55383fa5689357bcdd2c8036725a55ed632bc.(CVE-2023-3609)
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 crash and denial of service.(CVE-2023-3772)
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 according to packet sizes without bounds checks.We recommend upgrading past commit 3e337087c3b5805fe0b8a46ba622a962880b5d64.(CVE-2023-3611)
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(CVE-2023-35001)
