Descriptions

In the Linux kernel, the following vulnerability has been resolved: crypto: qat - add param check for RSA Reject requests with a source buffer that is bigger than the size of the
key. This is to prevent a possible integer underflow that might happen
when copying the source scatterlist into a linear buffer.

In the Linux kernel, the following vulnerability has been resolved: crypto: qat - add param check for RSA Reject requests with a source buffer that is bigger than the size of the key. This is to prevent a possible integer underflow that might happen when copying the source scatterlist into a linear buffer.

This update for the Linux Kernel 5.3.18-150300_59_164 fixes several issues. The following security issues were fixed. Net: tun: Fix use-after-free in tun_detach. Crypto: qat - add param check for RSA. Crypto: qat - add param check for DH. Tap: add missing verification for short frame. Net: inet6: do not leave a dangling sk pointer in inet6_create.
