kernel: openvswitch: integer underflow leads to out-of-bounds write in reserve_sfa_size()
An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of actions, while copying and reserving memory for a new action of a new flow, the reservesfasize function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write...

Linux kernel 数字错误漏洞
Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A numeric error vulnerability exists in the Linux kernel that stems from an integer coercion error found in the openvswitch kernel module. Given enough operations, the...
The vulnerability of the reserve_sfa_size() function in the openvswitch module of the Linux operating system allows a hacker to increase their privileges or cause service failures.
The vulnerability of the reservesfasize function in the openvswitch module of the Linux operating system is related to writing beyond the buffer boundaries in memory. Exploiting this vulnerability can allow an attacker to increase their privileges or cause service failures...
