Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: nvmet-tcp: bounds checks were added in nvmettcpbuildpduiovec. The nvmettcpbuildpduiovec function could exceed cmd-req.sg when the PDU length or offset exceeded sgcnt, and then use bogus values of sg-length/offset. This led to...
