netrc and default credential leak

A flaw was found in libcurl in the way libcurl handles previously used connections without accounting for 'issuer cert' and comparing the involved paths case-insensitively. This flaw allows libcurl to use the wrong connection. The highest threat from this vulnerability is to confidentiality.

An issue was discovered in the Linux kernel before 5.7.3, related to mm/gup.c and mm/hugememory.c. The getuserpages (aka gup) implementation, when used for a copy-on-write page, does not properly consider the semantics of read operations and therefore can grant unintended write access, aka CID-17839856fd58.

Two memory leak flaws were found in the Linux kernel's mwifiexpcieinitevtring() function. A local attacker, able to reload the kernel module or hotplug Marvell WiFi hardware using this driver, can cause a denial of service (memory consumption) by triggering mwifiexmappcimemory() failures.
