USN-6454-3: Linux kernel (ARM laptop) vulnerabilities

Kyle Zeng discovered that the netfilter subsystem in the Linux kernel contained a race condition in IP set operations in certain situations. A local attacker could use this to cause a denial of service system crash. CVE-2023-42756 Alex Birnberg discovered that the netfilter subsystem in the Linux...

Vulnerability of the net/netfilter/ipset/ip_set_hash_netportnet.c module in Linux kernel: This vulnerability allows attackers to compromise the confidentiality, integrity, and accessibility of protected information, or to enhance their privileges.

The vulnerability in the net/netfilter/ipset/ipsethashnetportnet.c module of the Linux operating system is related to the incorrect definition of CIDRPOS used in the functions mtypeaddcidr and mtypedelcidr. Exploiting this vulnerability can allow an attacker to compromise the confidentiality,...

DEBIAN-CVE-2023-42756

A flaw was found in the Netfilter subsystem of the Linux kernel. A race condition between IPSETCMDADD and IPSETCMDSWAP can lead to a kernel panic due to the invocation of ipsetput on a wrong set. This issue may allow a local user to crash the system...

kernel: out-of-bounds write in xt_compat_target_from_user() in net/netfilter/x_tables.c

A flaw was discovered in processing setsockopt IPTSOSETREPLACE or IP6TSOSETREPLACE for 32 bit processes on 64 bit systems. This flaw will allow local user to gain privileges or cause a DoS through user name space. This action is usually restricted to root-privileged users but can also be leverage...
