Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: iouring/memmap: The nrpages value is cast to sizet before shifting. If the allocated size exceeds UINTMAX, it is necessary to cast the mr-nrpages value to sizet to prevent an overflow. In practice, this isn’t a major issue, as th...

GHSA-MJ73-J457-8X9Q maxminddb's `Reader::open_mmap` unsoundly marks unsafe memmap operation as safe

maxminddb prior to version 0.27 declared Reader::openmmap as safe despite wrapping an inherently unsafe memmap2 operation with no extra step done to guarantee safety. This could have led to undefined behaviour if the file were to be modified on disk while the memory map was still active...
