Updated kernel-linus packages fix security vulnerabilities

This kernel-linus update is based on upstream 5.10.37 and fixes at least the following security issues: It was discovered that the iouring implementation of the Linux kernel did not properly enforce the MAXRWCOUNT limit in some situations. A local attacker could use this to cause a denial of...

An out-of-bounds (OOB) memory access flaw was found in fs/f2fs/node.c in the f2fs module in the Linux kernel in versions before 5.12.0-rc4. A bounds check failure allows a local attacker to gain access to out-of-bounds memory leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to system availability.
