The Linux kernel has several security flaws

Threat Level Vulnerability Report For a detailed threat advisory, download the pdf file here Summary The Linux kernel is vulnerable to a vulnerability that allows remote attackers to execute arbitrary code on affected installations. This vulnerability can be exploited without authentication, but...

The vulnerability of the smb2_write function (fs/ksmbd/smb2pdu.c) in the ksmbd module of the Linux operating system allows a hacker to disclose protected information or cause service failures.

The vulnerability of the smb2write function fs/ksmbd/smb2pdu.c in the ksmbd module of the Linux operating system relates to the ability to read data beyond the buffer boundaries in memory. Exploiting this vulnerability can allow a remote attacker to disclose sensitive information or cause service...
