MGASA-2022-0101 Updated kernel-linus packages fix security vulnerabilities

This kernel-linus update is based on upstream 5.15.28 and fixes at least the following security issues: Non-transparent sharing of branch predictor selectors between contexts in some IntelR Processors may allow an authorized user to potentially enable information disclosure via local access...

CVE-2022-0742

A memory leak flaw was found in the Linux kernel’s ICMPv6 networking protocol, in the way a user generated malicious ICMPv6 packets. This flaw allows a remote user to crash the system. Mitigation Mitigation for this issue is either not available or the currently available options dont meet the Re...

However, when processing subsequent options the packet...

CVE-2020-7469

The CVE-2020-7469 issue affects FreeBSD’s ICMPv6 handling: the routing option handler caches a pointer to a packet buffer containing an ICMPv6 message, which can be freed later, risking a use-after-free when the pointer is dereferenced. A remote attacker could trigger a read of freed kernel memor...

CVE-2021-28362

An issue was discovered in Contiki through 3.0. When sending an ICMPv6 error message because of invalid extension header options in an incoming IPv6 packet, there is an attempt to remove the RPL extension headers. Because the packet length and the extension header length are unchecked with respec...

CVE-2021-28362

CVE-2021-28362 affects Contiki (through 3.0). An ICMPv6 error triggered while processing invalid IPv6 extension headers can underflow packet length/extension header length in rpl-ext-header.c, enabling construction of an invalid extension header that may cause memory corruption and Denial-of-Serv...
